T-cell Immunoglobulin and Mucin-Domain-Containing Molecule-3 (TIM3) is expressed on T-helper type 1 lymphocytes, and other immune cells including dendritic cells and natural killer cells. SensiStain Anti-TIM3 Antibody is developed for the specific staining of TIM3 in tissue samples. TIM3 overexpression has been indicated in CD4+ tumor-infiltrating lymphocytes, which also includes those with non-small cell lung cancer associated with poor prognoses.
