Human PSMA4 ELISA Kit (HUFI07011)

The PSMA4 protein (Proteasome Subunit Alpha 4, also known as PSC9 or HC9) is a constitutive alpha-ring subunit of the 20S proteasome core particle, which carries out the chymotrypsin-like, trypsin-like, and caspase-like activities responsible for most cytosolic protein turnover in eukaryotic cells. This Assay Genie immunoassay kit is supplied in a single-use microplate configuration with capture antibody pre-coated on the well plate, and the reagents should be stored refrigerated to maintain binding activity through the stated shelf life. The kit is intended for research use only and supports quantitative studies in vitro of PSMA4 expression in human clinical research specimens, complementing downstream applications such as western blot validation, immunohistochemistry on tissue sections, and gene-expression analysis by PCR. Independent studies have linked altered PSMA4 levels to multiple myeloma, diffuse large B-cell lymphoma, and to neurodegenerative disease models where proteasome dysfunction is implicated, making this reagent useful for biomarker discovery and pathway-focused investigation. Standard laboratory microplate absorbance instrumentation is required to read the assay, and the protocol is compatible with common plate washers and reagent dispensers found in most research laboratories.
