Human Chromogranin-A (CHGA) ELISA Kit

Manufactured by Assay Genie, this Sandwich ELISA kit enables the quantitative measurement of human Chromogranin-A (CHGA) in serum, plasma, cell culture supernatants, tissue homogenates, and other biological fluids. Chromogranin A is a neuroendocrine secretory protein that serves as a marker for neuroendocrine tumors and related disorders, and the kit is intended for research use only, with applications in cancer research.

The assay delivers a sensitivity of 32pg/mL and a detection range of 78-5000pg/mL, with intra-assay precision of 6.3% CV and inter-assay precision of 10.7% CV. Recovery averages 108% in serum (range 102-114%) and 110% in plasma (range 104-116%). The kit demonstrates specificity for natural and recombinant human Chromogranin-A. The target protein is also known by the synonyms Pituitary secretory protein I, SP-I, and CgA, and corresponds to UniProt entry P10645.
