Human STEAP4 (STEAP family member 4) ELISA Kit (HUFI08419)

Assay Genie supplies this STEAP4 quantification kit with a complete reagent set, including a sealed microplate pre-coated with capture antibody, lyophilized standards, and sufficient buffers for the full protocol run with up to 40 samples measured in duplicate. The assay is calibrated for human STEAP4 with no significant cross-reactivity reported against mouse Steap4 or the related STEAP family members STEAP1, STEAP2, and STEAP3, supporting clear interpretation of human adipose tissue and inflammatory signaling studies. The kit has been validated internally for cell culture supernatant samples, expanding utility for in vitro macrophage polarization and adipocyte inflammation research where STEAP4 induction by TNF-alpha and IL-6 is well documented. Each kit includes a lot-specific certificate of analysis, and reconstituted standards remain stable for approximately 30 days when aliquoted and frozen at -20 degrees C, while the TMB substrate reaction develops within 15 to 30 minutes after stop solution addition for routine plate-reader quantification.
