ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies.Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Clone 1E20 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects Cytokeratin-20. It targets an epitope within 23 amino acids from the C-terminal region.

KLH-conjugated linear peptide corresponding to 23 amino acids from the C-terminal region of human Cytokeratin-20.

Keratin, type I cytoskeletal 20 (UniProt: P35900; also known as Cytokeratin-20, CK-20, Keratin-20, K20, Protein IT) is encoded by the KRT20 gene (Gene ID: 54474) in human. Cytokeratin-20 is a heterotetramer of two type I and two type II keratins of the intermediate filament family. It is expressed predominantly in the intestinal epithelium and in luminal cells of colonic mucosa. Its expression is also observed in the Merkel cells of keratinized oral mucosa. It is recognized as a marker of intestinal cell differentiation and is also an excellent marker for certain types of carcinomas, such as adenocarcinomas of the colon, transitional cell carcinomas of the bladder and Merkel cell tumors of the skin. Cytokeratin-20 It plays a significant role in maintaining keratin filament organization in intestinal epithelia and when phosphorylated, it also plays a role in the secretion of mucin in the small intestine. It is reported to undergo hyperphosphorylation at serine 13 during the early stages of apoptosis, which becomes less prominent during the later stages. Phosphorylation at serine 13 is shown to increase in response to stress brought on by cell injury. During apoptosis it is cleaved at Asp 228 by caspases. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

30 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
