Human STUB1 ELISA Kit

From Assay Genie, this sandwich ELISA kit is designed for the quantitative measurement of human STUB1 (STIP1 Homology and U-Box Containing Protein 1) in serum, plasma, cell culture supernatant, cell or tissue lysate, and other liquid samples. STUB1 is an E3 ubiquitin-protein ligase that functions in protein folding, turnover, and protein quality control, with dysregulation implicated in Parkinson's disease, Alzheimer's disease, and cancer. The associated UniProt entry is Q9UNE7 and the kit is categorised within the Epigenetics and Nuclear Signaling research area. Reported synonyms include CHIP, UBOX1, HSPABP2, NY-CO-7, and SDCCAG7.

The assay uses a double-antibody sandwich format with colorimetric readout. Reported sensitivity is 18.75 pg/mL, with a measurable range of 31.25-2000 pg/mL. Storage is recommended at 2-8°C for 12 months. Reported linearity in serum (n=5) spans 84-100% across 1:2 to 1:8 dilutions, with EDTA plasma at 80-103% and heparin plasma at 80-105%. Reported recovery averages 94% in serum, 96% in EDTA plasma, and 98% in heparin plasma.
