Assay #2: N/A

Endotoxin Level: <1 EU/μg by LAL method

Activity (Specifications/test method): N/A

Biological activity: Measured by its ability to inhibit anti-CD3 induced proliferation of stimulated human T cells. Human T lymphocytes cultured for 72 hours with PHA were incubated for an additional 3 days in 96 well plates coated with 500 ng/ml anti-CD3 and rhTIM1. The ED50 for this effect is typically 0.15-1.0 μg/ml.

Results: Measured by its ability to inhibit anti-CD3 induced proliferation of stimulated human T cells.

The ED50 for this effect is typically 0.15-1.0 μg/ml.

Binding Capacity: N/A

Unit Definition: N/A

Molecular Weight: This protein contains a poly histidine tag at C-terminus and has a calculated MW of 31.3 kDa after removal of signal peptide. In DTT-reduced SDS-PAGE, rhHAVCR1 protein migrates as 80-100 kDa poly peptide due to high glycosylation.

Concentration: N/A

Appearance: Lyophilized

Physical form description: Lyophilized from 0.22 μm filtered solution in PBS, pH 7.4. Normally Mannitol or Trehalose is added as protectants before lyophilization.

Reconstitution Instructions: Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.

Background Information: Hepatitis A virus cellular receptor 1 also known as HAVCR1, HAVCR, KIM1, TIM, TIM1, TIMD1, is widely expressed with highest levels in kidney and testis. The protein encoded by HAVCR1 gene is a membrane receptor for both human hepatitis A virus (HHAV) and TIMD4. The encoded protein may be involved in the moderation of asthma and allergic diseases. The reference genome represents an allele that retains a MTTVP amino acid segment that confers protection against atopy in HHAV seropositive individuals. Three transcript variants encoding the same protein have been found for this gene. HAVCR1 may play a role in T-helper cell development, the regulation of asthma and allergic diseases and in kidney injury and repair. In case of human hepatitis A virus (HHAV) infection, functions as a cell-surface receptor for the virus.

Amino acid sequence: N/A

Handling: Centrifuge the vial prior to opening.
