Product Summary for Human TIM-3 Quantikine ELISA Kit
The Quantikine Human TIM-3 Immunoassay is a 2.5 hour solid phase ELISA designed to measure TIM-3 levels in cell culture supernates, cell lysates, serum, plasma, and urine. It contains NS0-expressed recombinant human TIM-3 and antibodies raised against the recombinant protein. Results obtained for naturally occurring human TIM-3 showed linear curves that were parallel to the standard curves obtained using the Quantikine Human TIM-3 Immunoassay standards. These results indicate that this kit can be used to determine relative mass values for natural human TIM-3.

Precision
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.

Background: TIM-3
TIM-3 (T cell immunoglobulin and mucin domain-3), also known as HAVCR2 is an immunosuppressive protein that enhances tolerance and inhibits anti-tumor immunity. It is upregulated on several populations of activated myeloid cells (macrophage, monocyte, dendritic cell, microglia, mast cell) and T cells (Th1, CD8+, NK, Treg). TIM-3 ligation by Galectin-9 attenuates CD8+ and Th1 cell responses and promotes the activity of Treg and myeloid derived suppressor cells. Dendritic cell-expressed TIM-3 dampens inflammation by enabling the phagocytosis of apoptotic cells and the cross-presentation of apoptotic cell antigens. TIM-3 also binds the alarmin HMGB1, thereby preventing the activation of TLRs in response to released tumor cell DNA.
