Human Mucin 4 (MUC4) ELISA Kit

Built around a two-site immunoassay design, this ELISA kit from Assay Genie enables quantitative measurement of human Mucin 4 (MUC4), a high-molecular-weight transmembrane glycoprotein expressed at the apical surface of epithelial cells lining the respiratory, gastrointestinal, and reproductive tracts. MUC4 contributes to epithelial lubrication and cell signaling through its interaction with the ErbB2 receptor, and altered expression has been documented in multiple carcinomas, including pancreatic ductal adenocarcinoma, breast carcinoma, ovarian carcinoma, and selected lung cancers, where it is implicated in tumor progression, metastasis, and chemoresistance. Researchers employ this assay to investigate MUC4 levels across benign and malignant epithelial contexts, to correlate expression with clinical staging, and to monitor changes in patient-derived samples during treatment response studies. Each kit supports ninety-six assays in a microplate configuration, is intended for in vitro research use only, and is suitable for work involving cell culture supernatants, tissue-derived preparations, and matched biofluid samples. Scientists studying mucin biology, oncology biomarker discovery, and epithelial-mesenchymal transition pathways will find this kit relevant to their workflows.
