Epithelial specific antigen (ESA) is a 40kD cell surface glycoprotein. NCL-ESA demonstrates a very broad pattern of reactivity with the majority of human epithelial tissue and only rarely labels mesothelial cells. The major application of NCL-ESA is as a general epithelial cell marker. It can also be used in a panel of antibodies for the diagnosis of mesothelioma.
Store unopened lyophilised antibody at 4oC. Under these conditions, there is no significant loss in product performance up to the expiry date indicated on the vial label. The reconstituted antibody is stable for at least two months when stored at 4oC. For long term storage, it is recommended that aliquots of the antibody are frozen at -20oC (frost-free freezers are not recommended). Repeated freezing and thawing must be avoided. Prepare working dilutions on the day of use.
Storage: Store at -20 °C for one year. Avoid repeated freeze/thaw cycles
