Human Proteasome 26S Subunit, Non ATPase 4 (PSMD4) ELISA Kit

This Assay Genie kit provides quantitative measurement of human PSMD4 (also known as S5a or Rpn10), a non-ATPase regulatory subunit of the 26S proteasome that recognizes polyubiquitinated substrates destined for degradation. The product supports investigations of protein turnover, NF-κB signaling, and DNA damage response in human specimens, and accommodates diverse sample matrices commonly prepared in cell biology and oncology research. An absorbance-based signal generated on a standard microplate reader enables straightforward quantitation, while the kit format supplies all necessary reagents for research use only. Laboratories studying proteasome inhibitor pharmacology, biomarker validation, ubiquitin pathway dynamics, or altered proteasomal activity in cancer and neurodegeneration models will find the platform useful for tracking PSMD4 expression across experimental conditions, time courses, and treatment groups.
