TIM-1/KIM-1 Protein, Rat, Recombinant (His Tag)

• Background:

  HAV cellular receptor 1 (HAVCR1), also known as Kidney injury molecule 1 (KIM-1) and T cell immunoglobulin mucin 1 (TIM-1), is a type of integral membrane glycoprotein. KIM-1 protein is widely expressed with the highest levels in the kidney and testis. It has been shown to play a major role as a human susceptibility gene for asthma, allergy, and autoimmunity. IgA1lambda is a specific ligand of KIM-1 protein and that their association has a synergistic effect in virus-receptor interactions. KIM-1 involves in the pathogenesis of acute kidney injury. It had been confirmed that KIM-1 is a human urinary renal dysfunction biomarker. Moreover, KIM-1 protein is a novel regulatory molecule of flow-induced calcium signaling.

• Gene Name:

  Hepatitis A virus cellular receptor 1

• Expression System:

  HEK293 Cells

• Tag:

  N-His

• Endotoxin:

  < 1.0 EU per μg of the protein as determined by the LAL method.

• Purity:

  > 97 % as determined by SDS-PAGE.

• Activity:

  At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

• Form:

  Lyophilized

• Buffer:

  Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

• Function:

  Immune Checkpoint Proteins, Diagnostic proteins

• Molecular Weight:

  The recombinant rat HAVCR1 comprises 237 amino acids and predicts a molecular mass of 26.7 kDa. As a result of glycosylation, the apparent molecular mass of the rat HAVCR1 is approximately 55-65 kDa in SDS-PAGE under reducing conditions.

• Storage Conditions:

  In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
