Recombinant Mouse TIM-1/KIM-1/HAVCR Protein Summary

Purity
>95%, by SDS-PAGE under reducing conditions and visualized by silver stain
Endotoxin Level
<0.10 EU per 1 μg of the protein by the LAL method.
Activity
Measured by its ability to induce IL-6 or TNF-alpha secretion by RAW 264.7 mouse monocyte/macrophage cells. The ED50 for this effect is 0.1-0.4 µg/mL. Measured by its ability to bind THP‑1 human acute monocytic leukemia cells. As determined by flow cytometric analysis, there is a greater than 3 fold increase in the fluorescence of apoptotic THP-1 cells treated with 0.5 μg/mL recombinant mouse TIM-1/His and Mouse Anti-polyHistidine PE-conjugated Monoclonal Antibody (Catalog # IC050P) compared to cells stained with anti‑Mouse Anti‑polyHistidine PE-conjugated Monoclonal Antibody alone.

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: TIM-1/KIM-1/HAVCR

TIM‑1 (T cell‑immunoglobulin‑mucin; also KIM‑1 and Tapr) is a 70 ‑ 80 kDa, type I transmembrane glycoprotein member of the TIM family of immunoglobulin superfamily molecules (1, 2, 3, 4). This gene family is involved in the regulation of Th1 and Th2‑cell‑mediated immunity. In mouse, there are eight known TIM genes (# 1 ‑ 8) vs. only three genes in human (# 1, 3 & 4) (1, 2). Mouse TIM‑1 and ‑2 are counterparts of human TIM‑1, while mouse TIM‑5 through TIM‑8 have no human counterparts (2). Mouse TIM‑1 (isoform 2) is synthesized as a 282 amino acid (aa) precursor that contains a 21 aa signal sequence, a 193 aa extracellular domain (ECD), a 21 aa transmembrane segment and a 47 aa cytoplasmic domain (5, 6). The ECD contains one V‑type Ig‑like domain and a mucin region characterized by multiple T‑S‑P motifs. The mucin region undergoes extensive O‑linked glycosylation. The mouse TIM‑1 gene is highly polymorphic and, based on rat, may undergo alternate splicing (4, 6). One isoform (termed isoform 1) possesses a 23 aa insertion after Pro182 (GenBank # NP_599099). Another splice variant (of isoform 1) shows a 15 aa deletion in the mucin region of the ECD (6). This difference is associated with a decreased susceptibility to asthma. In human, TIM‑1 is known to circulate as a soluble form that arises from cleavage by an undefined MMP, releasing an 85 ‑ 90 kDa soluble molecule (7). In mouse, a 60 ‑ 65 kDa soluble form has also been detected (in urine) that presumably arises from proteolytic processing (8). In‑house data from R&D Systems Inc. has demonstrated the presence of soluble TIM‑1 in mouse circulation. The ECD of mouse TIM‑1 shares 37% and 81% aa sequence identity with human and rat TIM‑1 ECD, respectively. There are at least three reported ligands for TIM‑1, and include TIM‑4, phosphatidlyserine and the hepatitis A virus (3, 9, 10). However, still others are believed to exist, and based on the ligand for TIM‑3, one might be an S‑type lectin (11). TIM‑1 ligation induces T cell proliferation and promotes cytokine production (1, 11). In particular, it induces IL‑4 production, and requires the TIM‑1 cytoplasmic tyrosine phosphorylation motif (5).
