Mouse Quiescin Q6 Sulfhydryl Oxidase 1 (QSOX1) ELISA Kit

Quiescin Q6 sulfhydryl oxidase 1 (QSOX1) is an FAD-dependent enzyme that introduces disulfide bonds into nascent secretory proteins, and the Assay Genie Mouse QSOX1 ELISA Kit enables quantitative measurement of this enzyme in mouse-derived research specimens. This immunoassay supports studies of oxidative protein folding, extracellular matrix remodeling, and tumor microenvironment biology, where QSOX1 expression has been reported as a stromal activation marker in published murine cancer models.

Reagents are supplied in a microplate layout suitable for 96 determinations, providing adequate throughput for cancer biology, secretory pathway, and metabolic disease investigations. The absorbance-based readout allows standard curve-based quantitation, and the assay has been validated across serum-derived, plasma-derived, and tissue homogenate sample matrices obtained from mouse model systems. Researchers profiling stromal activity in breast, prostate, and pancreatic tumor models frequently pair QSOX1 measurement with downstream markers of active matrix deposition.

For handling, store the kit at 4 °C, keep the substrate solution protected from light, and bring reagents to room temperature before use to ensure reproducible standard curves across runs.
