Ionpath Expands Biopharmaceutical Partnerships Program to Rapidly Deliver Novel Insights Utilizing the Company’s High-Definition Spatial Proteomics Platform<span class='news-meta'>Aug 26 2021</span>
New Spatial Proteomics Pilot Program provides streamlined path to high-definition spatial analysis of the tissue microenvironment
MENLO PARK, Calif., August 26, 2021 — Ionpath, Inc., the leader in high-definition spatial proteomics, today announced a new program for biopharmaceutical research organizations interested in piloting spatial phenotyping analyses of tissue samples leveraging the company’s Multiplexed Ion Beam Imaging (MIBI™) technology. Through this new program, customers can benefit from in-depth immune profiling and spatial analysis performed with the company’s 30-marker Checkpoint Panel on its MIBIscope™ System.
The MIBIscope platform provides a high-resolution view into the dynamics of proteins in their native tissue environment and architecture. The resulting actionable data allows researchers to not only explore the spatial relationships between a tumor and infiltrating immune cells but to also classify cells and perform the quantitative analysis of checkpoint expression that is critical to advancing immune system-based therapy development.
“Since launching our Spatial Proteomic Services last year, we’ve seen tremendous interest in the program with more than 400% growth and significant repeat business from biopharma R&D teams who experience the unmatched impact that MIBI data brings to their prospective trial programs,” said Dr. Sander Gubbens, CEO at Ionpath. “With this new pilot program, any biopharmaceutical company can quickly access high-definition spatial proteomic data and insights from our expert team that demonstrates the power MIBI data brings to their translational research.”
Customer tissue samples are stained with metal-tagged antibodies using a workflow similar to the gold standard IHC. The samples are then analyzed with the MIBIscope, where an ion beam liberates the metal tags that are then detected with a time-of-flight mass spectrometer – delivering fast acquisition with extraordinary resolution and sensitivity. The sample is not destroyed during imaging and can be stored for follow-on studies or utilized for additional analyses.
“MIBI truly is a game changer, unencumbered by the deficiencies of fluorescent technologies,” added Gubbens. “With our pilot program, new organizations will be able to see what they have been missing with other technologies and experience why our customers are expanding their use of MIBI – spanning from pre-clinical discovery to clinical trial sample analysis.”
The Spatial Proteomics Pilot Program uses Ionpath’s 30-marker Checkpoint Panel which provides classification of 26 cell populations and expression information for all cell types. Ionpath’s expert team of pathologists, immunologists and bioinformaticians deliver actionable insights including cell classification, quantitative analysis of checkpoint expression, spatial information, and comparative cohort analysis.

Groundbreaking Stanford Skin Cancer Study Uses Multi-Omics Approach Including Ionpath High Definition Spatial Proteomics <span class='news-meta'>Jul 23 2020</span>
MENLO PARK, Calif., July 23, 2020 — Specialized cells at the edge of growing skin cancers reduce immune response, Stanford researchers have reported in Cell. The study, available in print today, combined several techniques to analyze and precisely map the tumor microenvironment of squamous cell carcinoma (a common skin cancer) with single-cell level detail.
The team of Stanford researchers, led by Paul Khavari, MD, PhD, professor and chair of dermatology and the Carl J. Herzog Professor in Dermatology in the School of Medicine, combined single-cell resolution Multiplexed Ion Beam Imaging (MIBI™) with spatial transcriptomics and RNA sequencing to analyze a series of human cutaneous squamous cell carcinoma samples, along with matched normal skin. The aim was to understand the spatial context of tumor biology and identify cell types that drive drug resistance.
“We wanted to obtain a high-resolution view of the tumor microenvironment through a multi-pronged approach. Until our study, we had no idea how diverse of a cellular composition was present within this disease,” explains Andrew Ji, MD, Clinician, Post Doctoral Fellow at Stanford Medical School and co-lead author. “We leveraged single-cell RNA-sequencing to define the cell types present, but this required dissociating the samples, thereby losing their spatial and biological context. Without this critical piece of the puzzle, we cannot understand how these cells could potentially influence their surrounding neighbors.”
Ionpath’s high definition spatial proteomics platform, MIBI, provides quantitative protein expression on a single cell basis, with spatial content. This provides researchers with the ability to see not only what cells and biomarkers are present, but also where they are located in relation to each other.
“The high-throughput ability to define diverse cell types through single-cell RNA-sequencing has highlighted challenges with traditional imaging and staining methods,” says Sizun Jiang, PhD, co-lead author and Post Doctoral Fellow, Dept. of Microbiology and Immunology, Stanford University School of Medicine. “Ionpath’s next-generation MIBI platform enabled us to obtain a breadth of markers simultaneously and at single-cell resolution to place these diverse cells in their native context and understand what behaviors they may be engaging in. We hope that this leads to not only an improved understanding of tumor biology, but a new framework for profiling and understanding other human diseases.”
The researchers are now using this multi-omics approach to investigate cancer types beyond squamous cell carcinomas to provide novel insights and guide new cancer therapies that activate the immune system and use it in the fight against cancer.

Press Release: Journal Cell Features New Immunohistochemistry Imaging Technology from Ionpath that Images 40+ Proteins on a Single Slide<span class="news-meta">Sep 16 2018</span>
Menlo Park, California, Sept. 6th, 2018 — IonpathTM, a venture-backed commercial-stage pathology startup, today announced that a paper detailing the performance of its new Multiplexed Ion Beam Imaging (
The study leveraged Ionpath’s MIBIscopeTM instrument to define tumor and immune cell spatial compositions leading to a discovery of a cell signature that predicts therapeutic response for triple-negative breast cancer.
REVOLUTIONIZING TISSUE BIOPSY ANALYSIS
MIBI technology was invented in Prof. Garry Nolan’s lab and developed by Drs. Sean Bendall and Mike Angelo in the Department of Pathology at Stanford University. MIBI uses secondary-ion mass spectrometry (SIMS), a type of mass spectrometry traditionally used in the semiconductor industry, to image antibodies tagged with monoisotopic metal reporters, permitting 40+ proteins to be simultaneously measured.
The Ionpath MIBIscope platform, coupled with pathologist-validated reagents and downstream image analytics, will enable pathologists and scientists to better understand the complexities of the tissue microenvironment by delivering subcellular resolution, spatial and structural information than previously possible.
The MIBIscope is currently being piloted by top research institutes and
In addition, the MIBIscope has been selected as the only highly multiplexed IHC imaging platform for the National Cancer Institutes (NCI) Cancer Immune Monitoring and Analysis Center (CIMAC).
“For the first time, scientists will be able to simultaneously visualize many markers (with 40 plus channels available) on a single FFPE tissue slide with high sensitivity and resolution empowering unique discovery in immuno-oncology research,” said Harris Fienberg, Ionpath’s CEO.
Triple-negative breast cancer (TNBC) is known to be an aggressive and invasive form and represents about 15-20% of all breast cancers. It is generally diagnosed based on the lack of expression of three “receptors” known to fuel most breast cancer tumors: estrogen, progesterone, and HER2‐neu.
While it is known the immune system plays a critical role in cancer progression, getting a comprehensive view of the tumor-immune microenvironment is difficult using current technology. Challenges include autofluorescence, poor resolution resulting in incomplete spatial and contextual information for understanding protein expression within cells in FFPE Tissue.
In this study, Stanford scientists used MIBI technology to comprehensively profile the tumor microenvironment of 41 triple-negative breast cancer patients by simultaneously imaging 36 proteins at a subcellular resolution in diagnostic surgical pathology samples.
By using a multi-step analysis, including cell segmentation, single cell analysis and spatial analysis, the authors revealed how tumor expression and immune composition are interrelated within tissue context, that correlates with overall survival in TNBC. The authors showed how a multiplexed imaging approach can be used to stratify patient populations and identify a unique patient population that will respond to therapy.
“The work by Keren et al highlights the value of characterizing the intact tumor microenvironment with a comprehensive antibody panel and defining meaningful spatial relationships between tumor and infiltrating immune cells. The approach, MIBI-TOF, will be invaluable for analyzing potential mechanisms of immune evasion and responses to immunotherapy in multiple cancers”, said Dr. Margaret Shipp, Professor of Medicine and Director Lymphoma Program, Dana-Farber Cancer Institute.
The MIBI images collected are shared online and can be downloaded through a web-interface MIBItracker software available on the Ionpath company website.
MIBI is also currently being used to enable a variety of other applications including applications in neuroscience, where it is ideal for analyzing co-expression of dozens of proteins in brain biopsies (which are problematic for fluorescent-based technology) and autoimmunity where MIBI permits comprehensive analysis of the immune cells involved in the tissue-immune system interface. Additionally, further work is currently underway to identify biomarkers and stratify patients populations in clinical trials using MIBI.
