Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µl per million cells or 5 µl per 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

The T cell immunoglobulin and mucin domain containing protein (TIM) family encodes cell surface receptors that are involved in the regulation of T helper (Th-1 and Th-2) cell-mediated immunity. Tim-4, which is preferentially expressed on macrophages and dendritic cells, is the natural ligand of Tim-1. This binding leads to T-cell expansion and cytokine production. Unlike other members of the TIM family, TIM-4 lacks a putative tyrosine phosphorylation signal sequence in its intracellular domain. The TIM-4 gene maps to a locus associated with predisposition to asthma in both mice and humans and is connected to TIM-1-triggered Th2 responsiveness.
SMUCKLER (Spleen, mucin-containg, knock-out of lymphotoxin (LT)), TIMD4 (T-cell immunoglobulin and mucin domain containing 4)
Type 1 transmembrane glycoprotein and mucin domain containing protein 4.
Splenic CD14+, macrophages, immature DC.
TIM-1 ligation to TIM-4 induces T cell proliferation, promotes cytokine production, and aids in the regulation of Th2 immunity.
Phosphatiylserine is the receptor of TIM4, and TIM4 is a ligand of TIM1.
