Human USP21 ELISA Kit (HUFI05768)

Ubiquitin-specific peptidase 21 (USP21) is a nuclear and cytoplasmic deubiquitinating enzyme that cleaves ubiquitin from substrate proteins, regulating processes such as histone H2A Lys119 deubiquitination, Hippo-YAP signaling, and the DNA damage response. Assay Genie offers a quantitative immunoassay for researchers measuring USP21 protein levels in human experimental samples in vitro, supporting studies in oncology, cell signaling, and ubiquitin-proteasome biology. The kit is supplied as 96 individual assays and is intended for research use only. Components should be stored refrigerated between runs to maintain reagent stability across the shelf life of the product. The ELISA workflow accommodates standard laboratory plate readers and produces a measurable signal that correlates with USP21 concentration in each sample.
