Anti-Cytokeratin 5/6, clone D5/16 B4 ZooMAb®, Cat. No. ZMS1057, is a Mouse recombinant antibody that detects Cytokeratin 5/6 and is tested for use in Immunofluorescence, Immunohistochemistry (Paraffin), and Western Blotting.

Target description

Keratin, type II cytoskeletal 5 (UniProt: P13647; also known as 58 kDa cytokeratin, Cytokeratin-5, CK-5, Keratin-5, K5, Type-II keratin Kb5) is encoded by the KRT5 gene (Gene ID: 3852) in human. Keratins are the intermediate filament proteins of epithelia that display high degree of molecular diversity. They are heteropolymeric filaments formed by pairing of type I and type II keratins that are expressed in a highly specific patterns depending on the epithelial type and stage of cellular differentiation. Keratins contain a central rod domain of about 310 amino acids with alpha-helical conformation bordered by non-helical head and tail domains of variable length. The head domain consists of subdomains V1 and H1. The central alpha helical rod domain is composed of subdomains 1A, 1B, 2A, and 2B connected by the linkers L1, L12, and L2. The tail domain then consists of subdomains H2 and V2. They provide stability between epithelial cells and their attachment to basement membrane. Keratins also serve as tumor markers and epithelial differentiation markers. Multiple human epithelial keratins have been resolved with 2D-gels electrophoresis. These can be divided into acidic (pI 5.7) and basic (pI 6.0) subfamilies. The acidic keratins have molecular weights that range from 40 to 56 kDa. The basic keratins have molecular weights that range from 52 to 67 kDa. Members of the acidic and basic subfamilies are reported to be present in pairs. The composition of keratin pairs varies with the epithelial cell type, stage of differentiation, cellular growth environment, and the disease state. Cytokeratins 5 and 6 are in high frequency in mesothelial cells, as opposed to cells of adenocarcinoma and are shown to be a reliable marker for mesothelioma and squamous cell carcinoma of the lung. Clone D5/16 B4 recognizes cytokeratin 5 and 6. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant mouse monoclonal antibody IgG, lyophilized in PBS with 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.

Reconstitution

300 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.

Storage and Stability

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.
