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.

特異性

Clone 73-10 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Programmed cell death 1 ligand 1 (PD-L1/CD274). It targets an epitope within the C-terminal region.

免疫原

KLH-conjugated linear peptide from the C-terminal region of human PD-L1.

應用

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

標靶描述

Programmed cell death 1 ligand 1 (UniProt: Q9NZQ7; also known as PD-L1, PDCD1 ligand 1, Programmed death ligand 1, hPD-L1, B7 homolog 1, B7-H1, CD274) is encoded by the CD274 (also known as B7H1, PDCD1L1, PDCD1LG1, PDL1) gene (Gene ID: 29126) in human. PD-L1 is a single-pass type I membrane glycoprotein that plays a critical role in induction and maintenance of immune tolerance to self. It is expressed on activated T- and B-cells, dendritic cells, keratinocytes, and monocytes. Higher expression has also been reported in heart, skeletal muscle, placenta, and lung. . It is synthesized with a signal peptide (aa 1-18), which is subsequently cleaved off to produce the mature protein that contains a large extracellular domain (aa 19-238), a transmembrane domain (aa 239-259), and a cytoplasmic tail (aa 260-290). The extracellular region contains an Ig-like V-type domain (aa 19-127) and an Ig-like C2-type domain (aa 133-225). PD-L1 is expressed on activated T- and B-cells, dendritic cells, keratinocytes, and monocytes. Higher expression has also been reported in heart, skeletal muscle, placenta, and lung. It plays a critical role in induction and maintenance of immune tolerance to self. When engaged together with the TCR, the interaction of PD-1 with its ligands, PD-L1 and PD-L2, deliver an inhibitory signal to T cell proliferation and cytokine production. While PD-L1 is broadly expressed in hematopoietic and nonhematopoietic cells, PD-L2 expression is highly restricted to antigen presenting cells (APCs), including dendritic cells (DCs) and macrophages. The PD-1 pathway plays a key role in the progressive loss of effector T cell responses during chronic HIV infection. Cancer cells are reported to express higher levels of PD-L1 to subvert T-cell-mediated immunosurveillance. Under some conditions, blockade of this pathway can restore many T cell functions. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

外觀

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.

重構

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.

儲存和穩定性

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.
