Specificity
This MAb recognizes the 56.5kDa (CK10); 50kDa (CK14); 50kDa (CK15); 48kDa (CK16); 40kDa (CK19) keratins of the acidic (Type I or LMW) subfamily. Twenty human keratins are resolved with two-dimensional gel electrophoresis into acidic (pI 6.0) subfamilies. The acidic keratins have molecular weights (MW) of 56.5, 55, 51, 50, 50, 48, 46, 45, and 40kDa. MAb SPM116 recognizes the 65-67, 64, 59, 58, 56, and 52kDa keratins of basic subfamily. Many studies have shown the usefulness of keratins as markers in cancer research and tumor. SPM115/SPM116 is a broad spectrum anti pan-keratin antibody cocktail, which differentiates epithelial tumors from non-epithelial tumors e.g. squamous vs. adenocarcinoma of the lung, liver carcinoma, breast cancer, and esophageal cancer.

NCBI Description
Keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into epithelial keratins and hair keratins. This gene encodes an epithelial keratin that is expressed in the skin and eccrine sweat glands. The type II keratins are clustered in a region of chromosome 12q13.[provided by RefSeq, Jun 2009]

Product Notes
The KRT77 krt77 (Catalog #AAA438172) is an Antibody produced from Mouse and is intended for research purposes only. The product is available for immediate purchase. The Cytokeratin, Acidic (Type I or LMW) (Epithelial Marker) Mouse Monoclonal Antibody reacts with Human, Monkey, Cow, Dog, Rabbit, Mouse, Rat, Chicken, Turtle and may cross-react with other species as described in the data sheet. AAA Biotech's Cytokeratin, Acidic can be used in a range of immunoassay formats including, but not limited to, Flow Cytometry (FC/FACS), Immunofluorescence (IF), Western Blot (WB), Immunohistochemistry (IHC) Formalin. Flow Cytometry (0.5-1ug/million cells in 0.1ml) Immunofluorescence (1-2ug/ml) Western Blot (0.5-1ug/ml) Immunohistochemistry (Formalin-fixed) (0.5-1ug/ml for 30 min at RT) (Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes). Researchers should empirically determine the suitability of the KRT77 krt77 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Cytokeratin, Acidic, Monoclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
