Human REX1 ELISA Kit (HUFI06849)

REX1, also known as ZFP42, is a zinc finger transcription factor that serves as a defining marker of pluripotency in human embryonic stem cells and induced pluripotent stem cells (iPSCs). The Assay Genie kit incorporates a human-specific capture antibody pair, enabling quantitative measurement of endogenous REX1 protein in research specimens. Supplied as a microplate-based format with pre-coated wells, detection reagents, and lyophilized standards sufficient for 96 Assays, the protocol delivers an absorbance-based readout compatible with standard plate readers. On arrival, refrigerate the unopened kit, protect reagents from light, and minimize freeze-thaw cycles of reconstituted components to preserve antibody binding activity. Investigators in regenerative medicine, developmental biology, and cancer stem cell programs rely on quantitative REX1 measurements to monitor differentiation status, validate pluripotent cell lines, and characterize reprogramming efficiency. The product is intended for research use only and fits cell culture laboratories, disease modeling workflows, and translational studies of stem cell maintenance.
