This antibody is specific for human MUC1. The alpha subunit of MUC1 has cell adhesive properties. Can act both as an adhesion and an anti-adhesion protein. May provide a protective layer on epithelial cells against bacterial and enzyme attack. The beta su

While creating and characterizing this antibody, an ELISA was preformed on MUC1 and a 23-mer MUC1 peptide, E23 (CPAHGVTSAPDTRPAPGSTAPPA), Furthermore, the specificity of the antibody was confirmed using flow cytometry on MCF-7, BT-20 and 413BCR cell lines using the murine version of this antibody. Further, a chromium release assay was preformed using the murine version of this antibody on ZR75-1 cells. And finally the biodistribution of the mouse version of this antibody was tested. This was done on mice injected with ZR75-1 cancer cells (Qi et al, 2001; pmid:11839249). To assess the ability of this antibody to cure cancer mice inoculated with a Panc02.MUC1 cancer cell line were treated with the mouse version of this antibody. The antibody showed the ability to slow down or even cure cancer in these mice. Further, the MUC1 concentrations in the serum of the mice inoculated with a Panc02.MUC1 were tested with ELISA using the mouse version of this antibody. Then spleen and tumor tissue were tested for the presence of MUC1 in both flow cytometry and immunocytochemistry using the mouse version of this antibody. And finally ADCC activity of the mouse version of this antibody was performed using murine splenic NK cells (Mehla et al, 2017; pmid:29204701). The ability of this antibody to halt cancer progression in humans was assessed using the mouse version of this antibody. The antibody showed no significant difference in the progression of cancer. But it did show the ability to cause an anti-MUC1 response (de Bono et al, 2004; pmid:15550589). While creating a new PET scan agent to detect MUC1 postive cancers, flow cytometry was preformed on SKOV3, a human ovarian cancer cell line, using the mouse version of this antibody. Further, a radioimmunoassay was preformed on human serum using the mouse version of this antibody bound to 89 zirconium. Finally, a pet scan was preformed on mice inoculated with the SKOV3 ovarian cancer cell line; the cell line was stained using the mouse version of this antibody bound to 89 zirconium (Fung et al, 2020; pmid:32429033).
