Human Protein Disulfide Isomerase A4 (PDIA4) ELISA Kit

Researchers studying endoplasmic reticulum stress and protein folding homeostasis use the Assay Genie Human Protein Disulfide Isomerase A4 (PDIA4) ELISA Kit to quantify PDIA4 (also known as ERP72), a chaperone of the PDI family that catalyzes thiol-disulfide exchange, disulfide bond formation, and isomerization during oxidative protein folding. The kit is supplied in a 96-assay microplate format with all reagents required to generate a full standard curve, and has been validated for human samples across multiple preparation types. The assay supports studies of the unfolded protein response, ER stress signaling, and protein quality control in vitro. Applications include cancer biology, neurodegeneration, and metabolic disease research, where PDIA4 levels are tracked as a marker of ER stress and chaperone activity. This product is intended for research use only and is not validated for clinical or diagnostic decision-making.
