CST, 56005SF, PD-L1 (F3Z1T) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying CD274 mouse. Validated for Western Blotting,Immunohistochemistry (Paraffin). Highly specific and rigorously validated in-house, PD-L1 (F3Z1T) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #56005) is ready to ship. Product Usage Information This product is the carrier free version of products #80517 and #73552. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol. This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us . Optimal dilutions/concentrations should be determined by the end user. BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. Formulation Supplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. For standard formulation of this product see product # 80517 and # 73552 .​ Storage Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance. Specificity / Sensitivity PD-L1 (F3Z1T) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total mouse PD-L1 protein. Species Reactivity: Mouse Source / Purification Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the extracellular domain of mouse PD-L1 protein. PD-L1 (F3Z1T) is the preferred clone for immunohistochemical analysis of mouse tissues. Background Programmed cell death 1 ligand 1 (PD-L1, B7-H1, CD274) is a member of the B7 family of cell surface ligands that regulate T cell activation and immune responses. The PD-L1 ligand binds the PD-1 transmembrane receptor and inhibits T cell activation. PD-L1 was discovered following a search for novel B7 protein homologs and was later shown to be expressed by antigen presenting cells, activated T cells, and tissues including placenta, heart, and lung (1-3). Similar in structure to related B7 family members, PD-L1 protein contains extracellular IgV and IgC domains and a short, cytoplasmic region. Research studies demonstrate that PD-L1 is expressed in several tumor types, including melanoma, ovary, colon, lung, breast, and renal cell carcinomas (4-6). Expression of PD-L1 in cancer is associated with tumor-infiltrating lymphocytes, which mediate PD-L1 expression through the release of interferon gamma (7). Additional research links PD-L1 expression to cancers associated with viral infections (8,9).
