General description

Cytokeratin is a 52.5kD cytoplasmic structural protein that belongs to type II, neutral-to-basic subfamily. It consists of 29 different proteins which is the characteristic of epithelial and trichocytic cells. Monoclonal anti-cytokeratin peptide 8 antibody can be used as a marker for epithelial cell differentiation as well as a tool for tumor identification and classification. It can also be used in western blotting. Mouse anti-cytokeratin peptide 8 antibody reacts specifically with various human simple and complex epithelia like- liver, intestine, pancreas, urinary bladder, salivary gland, thyroid, prostate, mesothel, and placenta but not with stratified squamous epithelia. The product also does not react with non-epithelial tissues (exceptions-certain smooth muscle cells). This product has also shown cross reactivity for cytokeratin of rabbit, cow, dog, and cat.Monoclonal Anti-Cytokeratin 8 (mouse IgG1 isotype) is derived from the M20 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a cytokeratin preparation purified from the human breast carcinoma cell line MCF7.

Polycystic ovary syndrome (PCOS) affects approximately 4%-18% of all reproductive-aged women and is often accompanied by endometrial progesterone (P4) resistance. Endometrial cells from PCOS patients display increased progesterone receptor (PGR) expression; however, in vivo knockout studies and in vitro experiments
