Beschreibung

Allgemeine Beschreibung

Keratin, type I cytoskeletal 19 (UniProt: P08727; also known as Cytokeratin-19, CK-19, Keratin-19, K19) is encoded by the KRT19 gene (Gene ID: 3880) in human. Cytokeratins belong to a diverse group of intermediate filaments that participate in differentiation and maintain the structural integrity of epithelial cells. Cytokeratins share a common structural organization: a central -helical rod domain flanked by head and tail domains. An important unique feature of cytokeratins is their epithelial cell-type-specific expression. About 20 different cytokeratin proteins have been reported in higher animals in varying combinations during various stages of development. CK-19 belongs to the family of intermediate filament (IF) family but differs from other IF proteins in lacking the C-terminal tail domain. It is a heterotetramer of two type I and two type II keratins. CK-19 is expressed in a defined zone of basal keratinocytes in the deep outer root sheath of hair follicles. It is also observed in sweat glands, mammary gland ductal and secretory cells, bile ducts, bladder urothelium, and gastrointestinal tract. CK-19 has been shown to be an independent prognostic factor for pancreatic neuroendocrine tumors, especially the insulin-negative tumors. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. (Ref.: Jain, R., et al. (2010). Appl. Immunochem. Mol. Morphol. 18(1); 9-15).

Biochem./physiol. Wirkung

Clone 1B12 is a Rabbit recombinant monoclonal antibody that specifically detects human Cytokeratin-19. It targets an epitope within 20 amino acids from the C-terminal half.

Physikalische Form

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.

Angaben zur Herstellung

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.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
