The Quantikine® Human Serum TIM-1/KIM-1/HAVCR Immunoassay is a 4.5 hour solid phase ELISA designed to measure human TIM-1 in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant human TIM-1 and antibodies raised against the recombinant factor. Natural human TIM-1 showed dose-response curves that were parallel to the standard curves obtained using the Quantikine® kit standards. These results indicate that this kit can be used to determine relative levels of natural human TIM-1.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components.
The recovery of human TIM-1 spiked to levels throughout the range of the assay was evaluated.

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human TIM-1 were serially diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
TIM-1 (T cell immunoglobulin and mucin domain 1), also known as KIM-1 and HAVcr1, is expressed on many immune cell types and epithelial cells. It binds to phosphatidylserine (PS), LMIR5/CD300b, TIM-1 (homophilic), TIM-4, IgA, and the glycoproteins of a number of enveloped viruses. Its interaction with PS enables TIM-1 to mediate the phagocytosis and clearance of apoptotic cells. TIM-1 signaling costimulates T cell activation and enhances Th2 cytokine production. TIM-1 serves as a cellular entry receptor for hepatitis A virus, Ebolavirus and Marburgvirus. Polymorphisms are associated with susceptibility to atopy, autoimmunity, and severe hepatitis A virus infection in humans. A soluble form of TIM-1 is elevated in the urine during nephropathy.
