Description de la cible

HLA class I histocompatibility antigen, A alpha chain (UniProt: P04439; also known as Human leukocyte antigen A, HLA-A) is encoded by the HLA-A (also known as HLAA) gene (Gene ID: 3105) in human. HLA-A is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-24), which is subsequently cleaved off to produce the mature protein that contains an extracellular domain (aa 25-308), a transmembrane domain (aa 309-332), and a cytoplasmic domain (aa 333-365). It is ubiquitous in its distribution and its levels are up-regulated by interferon- , IL-1β, and TNF. It is an antigen-presenting major histocompatibility complex I molecule that in complex with β2-microglobulin displays primary viral and tumor-derived peptides on antigen-presenting cells for recognition by -β T cell receptor (TCR) on HLA-A-restricted CD8+ T cells. This helps antigen-specific T cell immune response to eliminate infected or transformed cells. It may also present self-peptides derived from the signal sequence of secreted or membrane proteins, although T cells specific for these peptides are usually inactivated to prevent autoreactivity. It typically presents intracellular peptide antigens of 8 to 13 amino acids that arise from cytosolic proteolysis via interferon- -induced immunoproteasome or via endopeptidase IDE/insulin-degrading enzyme. Only optimally assembled peptide-HLA- β2-microglobulin trimer is reported to translocate to the surface of antigen-presenting cells, where it interacts with TCR and CD8 co-receptor on the surface of T cells. Two isoforms of HLA-A have been described that are produced by alternative splicing. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.(Ref.: Parmentier, N., et al. (2010). Nat. Immunol. 11(5); 449-454; Robek, MD., et al. (2007). J. Virol. 81(2); 483-491).

Forme physique

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.

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.

Stockage et stabilité

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.
