Human POU3F4 ELISA Kit (HUFI07121)

The POU3F4 protein, also known as Brain-4 (BRN4) or OCT-9, is a POU-homeodomain transcription factor encoded on the X chromosome at Xq21.1. Loss-of-function mutations in this gene are the molecular cause of DFNX2 (formerly DFN3), the most common form of X-linked hereditary hearing loss, and are associated with characteristic cochlear malformation patterns such as incomplete partition type III. Researchers working in auditory neuroscience, inner ear development, and the genetics of hereditary deafness use this Assay Genie kit to quantify circulating POU3F4 levels in human samples. The protocol recommends a sample volume of 100 uL and delivers an absorbance-based readout on a standard microplate reader. Suitable for research use only; not intended for diagnostic or clinical procedures.
