|Specificity:||The antibody A53-B/A2 reacts with Rod domain of cytokeratin 19 (40 kDa) in human tissue. Cytokeratin 19 is not expressed in hepatocytes; it is often co-expressed with cytokeratin 7.|
|Immunogen:||MCF-7 human breast adenocarcinoma cell line|
Immunohistochemistry (paraffin sections)
|Purity:||> 95% (by SDS-PAGE)|
|Purification:||Purified from hybridoma culture supernatant by protein A-affinity chromatography.|
|Storage Buffer:||Phosphate buffered saline (PBS) with 15 mM sodium azide, approx. pH 7.4|
|Storage / Stability:||Store at 2-8°C. Do not use after expiration date stamped on vial label. For long-term storage aliquot and store at -20°C. Avoid freeze/thaw cycles.|
|Expiration:||See vial label|
|Lot Number:||See vial label|
|Background:||Cytokeratins are a subfamily of intermediate filaments and characterized by remarkable biochemical diversity. Cytokeratins are represented in epithelial tissues by at least 20 different polypeptides, molecular weight between 40 kDa and 68 kDa. The individual cytokeratin polypeptides are designated 1 to 20 and divided into the type I (acidic cytokeratins 9-20) and type II (basic to neutral cytokeratins 1-8) families.|
