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.

Specificity

Clone 3O12 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects Programmed cell death 1 ligand 1 (PD-L1). It targets an epitope within the extracellular domain.

Immunogen

His-tagged recombinant fragment corresponding to 218 amino acids from the extracellular region of from human PD-L1.

Application

Anti-PD-L1/CD274, clone 3O12 ZooMAb, Cat. No. ZRB1026, is a recombinant Rabbit monoclonal antibody that targets PD-L1/CD274 and is tested for use in Affinity Binding Assay, Immunocytochemistry, Immunohistochemistry (Paraffin) and Western Blotting.
Western Blotting Analysis: A 1:100 dilution from a representative lot detected PD-L1/CD274 in mouse placenta tissue lysate.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected PD-L1/CD274 in MDA-MB-231 and RAW264.7 cell lines.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected PD-L1/CD274 in human placenta and human lung cancer tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound human recombinant PD-L1/CD274 with a KD of 5.5 x 10-8 in an affinity binding assay.

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

Target description

Programmed cell death 1 ligand 1 (UniProt Q9NZQ7; also known as B7-H1, B7 homolog 1, CD274, PD-L1, PDCD1 ligand 1, Programmed death ligand 1) 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 protein 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. PD-1 and PD-1 ligands 1 and 2 (PD-L1 and PD-L2) are B7:CD28 family members that regulate T cell activation and peripheral tolerance. When engaged together with the TCR, the interaction of PD-1 with its ligands delivers 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. Under some conditions, blockade of this pathway can restore many T cell functions. PD-L1 is initially produced with signal peptide (aa 1-18) sequence, which is subsequently cleaved off to produce the mature protein with a large extracellular (aa 19-238) region that contains an Ig-like V-type domain (aa 19-127) and an Ig-like C2-type domain (aa 133-225), followed by a transmembrane domain (aa 239-259) and a cytoplasmic tail (aa 260-290). This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitution

0.3 mg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

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.
