Sandwich ELISA analysis of human interleukin-7 using Rat anti Human IL-7 (1012201) as a capture reagent and biotinylated Rat anti Human IL-7 (1012308) as a detection reagent with recombinant human IL-7 (PHP046) as antigen. Detection is by HRP conjugated streptavidin and substrate. Microtitre plate is read at O.D. 450 nm on the Bio-Rad iMark Microplate Absorbance Reader (Bio-Rad Catalog 168-1135). A human serum sample is indicated (green)
Recombinant human IL-7 is a 17.4 kDa protein comprised of 153 amino acids corresponing to the ful-length mature sequence.
IL-7 is a potent lymphoid cell growth factor acting on Pre-B, Pro-B and early T cells. In a dose dependent cell proliferation assay using 2E8 cells this product shows a specific activity of > 2 x 106 units/mg.
Recombinant human IL-7 is recognized by Rat anti Human IL-7 antibody clones BVD10-40F6 and BVD10-11C10 in ELISA.
Purified recombinant protein expressed in E. coli - lyophilised
Reconstitute with 0.1 ml distilled water. For extended storage the addition of 0.1% BSA is recommended. Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution.
