Background: TIM-3 (T-cell immunoglobulin and mucin-domain containing-3) is an immune checkpoint protein involved in negatively regulating immune responses. TIM-3 can be expressed on T cells including regulatory T cells, NK cells, monocytes and macrophages. In cancer, TIM-3 has been identified on tumor-infiltrating lymphocytes making TIM-3 an attractive target for reversing the immune suppression that is characteristic of the tumor microenvironment. Outside of cancer, TIM-3 contributes to T cell exhaustion that occurs from chronic viral infections and importantly helps mediate maternal-fetal tolerance.

Validation: Each lot of conjugated TIM-3 antibody is quality control tested by MIBIscope™ analysis of stained tissue microarrays using the appropriate positive and negative tissue field of views and are pathologist verified.

Recommended Usage: 1 uL of TIM-3 antibody per 100 uL staining volume using the MIBI™ Staining Protocol.
For optimal results, antibody should be titrated for each desired application.  Suggested starting range is 1:100.
