Cytokeratin 20
Full Product Description Cytokeratin (CK) filaments consist of a complex family of approximately 20 different cytokeratin polypeptides that provide structural integrity to epithelial cells. Our polyclonal pan-CK antibody showed no cross-reactivity to other filament types including vimentin, desmin, glial fibrillary acidic protein and neurofilament protein. This antibody can be used to discern whether a neoplasm originated from an epithelial or non-epithelial source, and also useful for the distinction of metastatic malignant tumors of epithelial origin. Positive tissue: Adenocarcinoma⁄skin⁄squ...

Pluronic F-127 *20% solution in DMSO* is a nonionic, surfactant polyol (molecular weight approximately 12,500 daltons) that has been found to facilitate the solubilization of water-insoluble dyes and other materials in physiological media. Pluronic F-127 is commonly used to help disperse the acetoxymethyl (AM) esters of our ion indicators as well as our cell tracer dyes such as CFDA-SE.

Proteinase K from the fungus Engyodontium album is a non-specific serine protease that is useful for general digestion of proteins. Proteinase K Remains Active: • Over a wide pH range (optimal activity between 6.5 and 9.5) • Under denaturing conditions (e.g. the presence of SDS or urea) • In the presence of metal chelating agents (e.g. EDTA) • At comparatively high temperatures (optimum digestion temperature is 65°C) Applications: Removal of endogenous nucleases during the preparation of DNA and RNA; preparation of tissue sections for in situ hybridization. Performance and Quality Testing: End...

Ambion® Acetylated BSA is used as a carrier protein and as an enzyme stabilizer in which the absence of contaminants such as nucleases and proteases is essential. Six tubes of 25 mg are provided, at a concentration of 40–50 mg/mL. The acetylation process inactivates any trace nuclease activity that might be present. While the acetylation process does change BSA's binding characteristics and makes it inhibitory in PCR reactions, it is routinely added to restriction digests. The molecular weight is ~66 kD. Acetylated BSA is rigorously tested for contaminating nonspecific endonuclease, exonucleas...
