Human SUB1 ELISA Kit (HUFI06273)

The SUB1 gene encodes a single-stranded DNA-binding protein (also known as PC4 or positive cofactor 4) that associates with RNA polymerase II, supports transcription pre-initiation complex stability, and contributes to DNA damage repair and chromatin remodeling. This Assay Genie kit uses a human-specific capture antibody paired with a matched detection reagent, enabling selective quantification of endogenous human SUB1 with no significant cross-reactivity reported for mouse or rat orthologs. The microplate layout supports in vitro research applications such as transcriptional stress studies, oxidative damage response, and oncogenic signaling pathway analysis. Reconstituted standards and frozen aliquots should be stored according to the package insert to preserve antibody binding activity.
