ターゲットの説明

B-lymphocyte antigen CD19 (UniProt: P15391; also known as B-lymphocyte surface antigen B4, Differentiation antigen CD19, T-cell surface antigen Leu-12, CD19) is encoded by the CD19 gene (Gene ID: 930) in human. CD19 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-19), which are subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 20-291), a transmembrane domain (aa 292-313), and a cytoplasmic domain (aa 314-556). It also contains two Ig-like C2-type domains (aa 20-113 and 176-277). CD19 expression has been reported in B cells in blood and lymph nodes. It is part of a complex that is composed of CD19, CD21, CD81, and CD225 in the membrane of mature B-cells. It interacts directly with CD81 via its second extracellular domain early during biosynthesis in the ER/pre-Golgi compartments and is essential for trafficking and compartmentalization of CD19 receptor on the cell surface of activated B cells. It functions as a coreceptor for the B-cell antigen receptor complex (BCR) on B-lymphocytes and is reported to decrease the threshold for activation of downstream signaling pathways and for triggering B-cell responses to antigens. Following B cell activation, CD19 is phosphorylated on tyrosine residues in a sequential order by Lyn. Phosphorylation of Tyr-531 is rapid, followed by phosphorylation at Tyr-409. Phosphorylation of Tyr-500 appears to be slow and transient. CD19 is shown to be essential for normal B cell differentiation and proliferation in response to antigen challenges. It also activates signaling pathways that lead to the activation of phosphatidylinositol 3-kinase and the mobilization of intracellular Ca2+ stores. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

物理的形状

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.

再構成

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.

保管および安定性

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.
