Human MPST (3-mercaptopyruvate sulfurtransferase) ELISA KIT (HUFI05065)

The 3-mercaptopyruvate sulfurtransferase (MPST) enzyme plays a central role in transsulfuration pathways and the endogenous biosynthesis of hydrogen sulfide, a gaseous signaling molecule implicated in vascular tone regulation, mitochondrial bioenergetics, and cellular redox homeostasis. Quantification of circulating MPST protein offers researchers a window into sulfur-amino-acid catabolism across cardiovascular, neurological, and metabolic disease models, making reliable measurement of this enzyme valuable for studies of cysteine metabolism and H2S biology. This quantitative immunoassay from Assay Genie is supplied as a complete kit containing reagents sufficient for 96 Assays, configured for in vitro research use only and validated for measurement of human MPST in laboratory specimens. Each kit is built around a microplate-based workflow with ready-to-use standards, detection antibodies, and wash buffer, supporting reproducible standard-curve generation on standard plate-reader instrumentation. The procedure accommodates small sample volumes, integrates readily into existing plate-reader protocols, and is well matched to projects where specimen availability is limited, including exploratory clinical research and translational studies of sulfur-transferase activity in disease.
