Anti-MUC3/MUC3A/MUC3B Antibody Picoband® Fluoro488 Conjugated

MUC3 consists of two genes, MUC3A and MUC3B, each encoding membrane-bound mucins possessing 2 epidermal growth factor-like domains. The MUC3 gene is mapped to chromosome 7. It was showed that synthetic peptide-mediated upregulation of MUC3 dramatically inhibited adherence of enteropathogenic E. coli or enterohemorrhage E. coli serotype O157:H7 to HT-29 human intestinal epithelial cells. Peptide stimulation altered expression of a number of transcription factors, including upregulation of SP1, CREB1, and CDX2. These transcription factors bound to consensus sites in the MUC3 promoter upon peptide stimulation and likely mediated MUC3 upregulation.
