Human Interferon-induced protein 44 (IFI44) ELISA Kit

From Assay Genie, the Human Interferon-induced protein 44 (IFI44) ELISA Kit is a colorimetric sandwich ELISA designed for the quantitative detection of IFI44 in human serum, plasma, tissue homogenates, cell culture supernates and other biological fluids. Specificity is reported for natural and recombinant human Interferon-induced protein 44, and the kit is intended for research applications in immunology.

Quoted performance specifications include a detection range of 0.78-50ng/mL and a sensitivity of 0.29ng/mL. Intra-assay CV is 4.5% and inter-assay CV is 8.2%. Linearity was assessed in serum, EDTA plasma and heparin plasma at 1:2, 1:4, 1:8 and 1:16 dilutions, with recovery in serum averaging 86% (range 80-92%) and in plasma averaging 88% (range 82-94%).

IFI44 is an interferon-induced protein that aggregates to form microtubular structures and is implicated in the cellular response to virus. Elevated IFI44 levels have been linked to autoimmune diseases, viral infections and inflammatory disorders, and the protein localises to the cytoplasm. The UniProt entry is Q8TCB0 with a reported molecular weight of 14,984 Da. For research use only.
