Descrizione del bersaglio

T-cell surface glycoprotein CD8 beta chain (UniProt: P10966; also known as CD8b) Is encoded by the CD8B (also known as CD8B1) gene (Gene ID: 926) in human. CD8β is a single-pass type I membrane glycoprotein that plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. It is synthesized with a signal peptide (aa 1-21), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 22-170), a transmembrane domain (aa 171-191), and a cytoplasmic domain (aa 192-210). Eight different isoforms of CD8β have been described that are generated by alternative splicing. Isoforms 1,3,5,6,7,8 are expressed in both thymus and peripheral CD8+ T cells. For efficient cell surface expression, it requires the CD8a as a partner and the heterodimer CD8a/CD8β localizes to lipid rafts due to CD8β cytoplasmic tail palmitoylation. In T-cells, it functions primarily as a coreceptor for MHC class I molecule:peptide complex. The antigens presented by class I peptides are derived from cytosolic proteins while class II derived from extracellular proteins. It interacts simultaneously with the T-cell receptor (TCR) and the MHC class I proteins presented by antigen presenting cells (APCs). In turn, recruits the Src kinase LCK to the vicinity of the TCR-CD3 complex. Once LCK recruited, it initiates different intracellular signaling pathways by phosphorylating various substrates ultimately leading to lymphokine production, motility, adhesion and activation of cytotoxic T-cells. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Stato fisico

Purified recombinant rabbit 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.

Ricostituzione

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.

Stoccaggio e stabilità

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.
