一般描述
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.

目标描述
Keratin, type II cytoskeletal 8 (UniProt: P05787; also known as Cytokeratin-8, CK-8, Keratin-8, K8, Type-II keratin Kb8) is encoded by the KRT8 (also known as CYK8) gene (Gene ID: 3856) in human. Cytokeratins belong to a diverse group of intermediate filaments that participate in differentiation and maintain the structural integrity of epithelial cells. They 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. CK8 is expressed in abundance in the epithelia of colon, bladder, ileum, and stomach. It is a type II, neutral to basic protein that together with cytokeratin-19 (KRT19) helps to link the contractile apparatus to dystrophin at the costameres of striated muscle. CK-8 can undergo phosphorylation on three major serine residues: Serine 23, 431, and 73. Serine 23 is highly conserved in all type II keratins. Phosphorylation at serine 73 is reported to increase during cellular stress. However, under normal conditions serine 73 remains largely dephosphorylated. It can also undergo O-glycosylation in a cell cycle-dependent manner and glycosylation increases its solubility and reduces stability by inducing proteasomal degradation. CK8 expression has been correlated with malignancy in leukoplakia and carcinomas of the head and neck and its expression has been observed in all non-small-cell lung cancers. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
外形
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.
重悬
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.
储存及稳定性
Recommend storage of lyophilized product at 2-8℃; 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℃, or -20℃ for long term storage. Avoid repeated freeze-thaws.
