1,25-(OH)2D3, the active metabolite of vitamin D, regulates immune responses in addition to its role in calcium, phosphorus, and bone metabolism. Recent data suggests that 1,25-(OH)2D3 blocks dendritic cell maturation influencing the development of regulatory T cells. High dose 1,25-(OH)2D3 monotherapy is effective at delaying acute rejection. The vitamin D receptor (VDR), which functions as a transcription factor, forms a complex with Smad 3, a TGFb-1 signaling protein, in rat renal lysates for treated recipients. 1,25-(OH)2D3 significantly prolonged graft survival, limited the degree of intersitial fibrosis and glomerulosclerosis, decreased urinary protein and altered Smad and MMP expression in a rat renal model of CAN. In a retrospective clinical study, that cadaveric renal transplant recipients with renal insufficiency placed on calcitriol demonstrate improved renal function and improved graft survival.
Pig 1,25-Dihydroxyvitamin D3 (1,25 DHVD3) ELISA Kit employs a two-site sandwich ELISA to quantitate 25-Dihydroxyvitamin in samples. An antibody specific for 25-Dihydroxyvitamin has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any25-Dihydroxyvitamin present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for 25-Dihydroxyvitamin is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of 25-Dihydroxyvitamin bound in the initial step. The color development is stopped and the intensity of the color is measured.
