Human Embryonic growth/differentiation factor 1 (GDF1) ELISA Kit

This Assay Genie Sandwich ELISA Kit is designed for the quantitative detection of Human Embryonic growth/differentiation factor 1 (GDF1, Uniprot P27539), a disulfide-linked homodimer of the TGF-beta superfamily that may mediate cell differentiation events during embryonic development. The kit is intended for research use only and is reactive with human samples, including serum, plasma, tissue homogenates, cell culture supernatants and other biological fluids.

According to the manufacturer's specifications, the assay provides a detection range of 31.2–2000 pg/mL with a sensitivity of 10 pg/mL. Reported precision is an intra-assay CV of 5.6% and an inter-assay CV of 9.4%. Linearity has been demonstrated in serum (86–121%), EDTA plasma (93–113%) and heparin plasma (94–127%) across serial dilutions, with average recoveries of 93% (87–99%) in serum and 95% (89–101%) in plasma. The kit shows specificity for natural and recombinant human GDF1, supporting studies in signal transduction, developmental biology and regenerative medicine.
