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.


Clone 1F7 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects human Programmed cell death protein 1. It targets an epitope within the N-terminal, extracellular domain.


GST/His-Tagged recombinant fragment corresponding to 150 amino acids from the extracellular domain of human Programmed cell death protein 1 (PD-1).


Quality Control Testing

Evaluated by Flow Cytometry in Molt4 cells.

Flow Cytometry Analysis: 0.1 μg of this antibody detected PD-1 in 250,000 Molt4 cells.

Tested Applications

Affinity Binding Assay: A representative lot of this antibody bound recombinant PD-1 fragment with a KD of 1.7 x 10-7 in an affinity binding assay.

Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected PD-1 in human tonsil tissue sections.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected PD-1 in HuT 78 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-PD-1, clone 1F7 ZooMAb®, Cat. No. ZRB1025, is a recombinant Rabbit monoclonal antibody that specifically targets PD-1 and is tested for use in Affinity Binding Assay, Flow Cytometry, Immunocytochemistry, and Immunohistochemistry (Paraffin).

Target description

Programmed cell death protein 1 (UniProt: Q15116; also known as Protein PD-1, hPD-1, CD279) is encoded by the PDCD1 (also known as PD1) gene (Gene ID: 5133) in human. PD-1 is a monomeric inhibitory cell surface receptor involved in the regulation of T-cell function during immunity and tolerance. PD-1 is synthesized with a signal peptide (aa 1-23), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 24-170), a transmembrane domain (aa 171-191), and a cytoplasmic domain (aa 192-288). PD-1 also contains a single N-terminal immunoglobulin variable region (IgV) like domain. PD-1 and its ligands, PD-L1 and PD-L2 play a key role in the maintenance of peripheral tolerance, a process by which the quiescence of autoreactive mature T cells is maintained. However, tumors and pathogens that cause chronic infections can exploit this pathway to escape T-cell mediated tumor-specific and pathogen-specific immunity. The effector functions of T-cells expressing PD-1 can be downregulated by PD-L1 or PD-L2 expressed by the tumor cells. PD-1 lacks SH2- or SH3-binding motifs on its cytoplasmic tail but contains the N-terminal sequence VDYGEL that forms an immunoreceptor tyrosine-based inhibition motif (V/I/LxYxxL), which recruits SH2 domain-containing phosphatases. The cytoplasmic tail also contains the C-terminal sequence TEYATI, which forms an immunoreceptor tyrosine-based switch motif (TxYxxL). PD-1 ligation is reported to inhibit the activation of T-cell receptor proximal kinases, which results in attenuation of Lck-mediated phosphorylation of ZAP-70 and initiation of downstream events. PD-1 is also reported to impair the activation of the MEK-ERK MAP kinase pathway by inhibiting activation of PLC- 1 and Ras. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
