Human Polycomb Group Ring Finger Protein 4 (PCGF4) ELISA Kit

This quantitative immunoassay from Assay Genie enables measurement of Polycomb Group Ring Finger Protein 4 (PCGF4), also known as BMI1, a core component of Polycomb Repressive Complex 1 that catalyzes monoubiquitination of histone H2A at Lys119. PCGF4 acts as a transcriptional repressor at developmental loci, and its expression is broadly studied in hematopoietic and neural stem cell maintenance, lineage commitment, and in oncology research where altered Polycomb activity contributes to tumor initiation, therapy resistance, and disease progression.

The 96-assay format kit supports quantification of PCGF4 across multiple human sample matrices, with validated protocols for tissue homogenates and other specimen types including cultured cell lysates and primary biopsy material. Reagents are provided in vials along with pre-coated strips, and the workflow is compatible with standard microplate readers used in routine laboratory settings. Each pack contains sufficient components for 96 individual determinations, requires refrigerated storage to preserve reagent activity, and is intended for research use only for in vitro applications such as chromatin regulation studies and stem cell biology research.
