Human anti Human cytokeratin 19/20 antibody recognizes human cytokeratin 20, and has been demonstrated to cross-react with cytokeratin 19. In immunohistology reactivity is seen both with tissues expressing only CK19 and with those expressing only CK20.
Human anti Human cytokeratin 19/20 antibody recognizes cytokeratins 19 and 20 as bands of ~40 kDa and ~45 kDa respectively by western blotting under reducing conditions.

Product Details
- Target Species
- Human
- Western Blotting
- Anti cytokeratin 19/20 antibody detects bands of approximately 40 kDa and 45 kDa in HeLa cell lysates.
- Product Form
- A bivalent human recombinant Fab selected from the HuCAL® GOLD phage display library, expressed in E. 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 product is supplied as a liquid.

Positive Control Lysate
- Lysate Composition
- 400μg HeLa lysate lyophilized in RIPA buffer.
- Lysate Reconstitution
- - If using DDT reconstitute the lyophilized lysate with 190μl DI H2O, add 200μl 2x Laemmli Sample Buffer and 10μl 2M DTT.
