Human SOSTDC1/USAG1 ELISA Kit

From Assay Genie, this sandwich ELISA kit employs a double-antibody format with colorimetric detection to quantify human SOSTDC1 (Sclerostin domain-containing protein 1). The assay is reactive to human specimens and accepts serum, plasma, cell culture supernatant, cell or tissue lysate, and other liquid samples. Reagents are stored at 2–8°C for 12 months.

Linearity across dilutions (1:2, 1:4, 1:8) is reported at 90–98%, 90–100%, and 92–104% for serum (n=5); 86–97%, 84–99%, and 84–97% for EDTA plasma (n=5); and 80–95%, 82–99%, and 80–99% for heparin plasma (n=5). Spike recovery ranges are 85–103% (average 92%) in serum, 85–102% (average 93%) in EDTA plasma, and 87–101% (average 93%) in heparin plasma. The kit is positioned for metabolism research, where SOSTDC1 is implicated in bone growth and development, making it relevant to studies of osteoporosis and other bone-related conditions.

Synonyms referenced for the target include USAG-1, USAG1, Ectodin, WISE, CDA019, cystine-knot containing secreted protein, Ectodermal BMP inhibitor, sclerostin domain containing 1, uterine sensitization-associated protein-1, and Uterine sensitization-associated gene 1 protein; the associated UniProt entry is Q6X4U4.
