HCA077A recognises human cytokeratin 18, a 45kD type I intermediate filament protein expressed by epithelial cells. The intermediate filaments are expressed as heterodimers in epithelial tissues. Cytokeratin 18 (CK18) is often co-expressed with cytokeratin 8 (CK8). The CK18/CK8 heterodimer is the major cytokeratin pair found in simple epithelia such as that found in the liver, intestine and breast ducts. CK18 plays an important role in maintaining epithelial cell integrity.
HCA077A has also been demonstrated to cross-react with cytokeratin 19.
Product Form
A bivalent human recombinant Fab selected from the HuCAL® GOLD phage display library, expressed inE. coli. This Fab fragment is dimerized via a helix-turn-helix motif. The antibody is tagged with a myc-tag (EQKLISEEDL) and a his-tag (HHHHHH) at the C-terminus of the antibody heavy chain. This antibody is supplied lyophilised.

This product requires antigen retrieval using heat treatment prior to staining of paraffin sections.Sodium citrate buffer pH 6.0 is recommended for this purpose.
Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
Western Blotting
HCA077A detects bands of approximately 42 and 45kDa in HT-29 cell lysates.
Prior to reconstitution store at +4oC.
After reconstitution store at -20oC.
Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
Shelf Life
12 months from date of reconstitution.
Licensed Use
For in vitro research purposes only, unless otherwise specified in writing by AbD Serotec.
Due to the presence of bovine serum albumin (BSA), this antibody is unsuitable for use as a capture reagent in sandwich ELISA applications. This product is also available without BSA,please enquire.
