验证数据展示

  • WB analysis using 66220-1-Ig (same clone as 66220-1-PBS)

    WB analysis using 66220-1-Ig (same clone as 66220-1-PBS)

    Various lysates were subjected to SDS PAGE followed by western blot with 66220-1-Ig (PD-1/CD279 antibody) at dilution of 1:15000 incubated at room temperature for 1.5 hours. The membrane was stripped and reblotted with HRP-conjugated Lamin B1 Monoclonal antibody (HRP-66095) as loading control. This data was developed using the same antibody clone with 66220-1-PBS in a different storage buffer formulation.

  • IHC staining of human tonsillitis using 66220-1-Ig (same clone as 66220-1-PBS)

    IHC staining of human tonsillitis using 66220-1-Ig (same clone as 66220-1-PBS)

    Immunohistochemical analysis of paraffin-embedded human tonsillitis tissue slide using 66220-1-Ig (PD-1/CD279 antibody) at dilution of 1:4000 (under 20x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 66220-1-PBS in a different storage buffer formulation.

    Ready-to-use IHC kits available with PD-1 antibody included
  • IF Staining of human tonsillitis using 66220-1-Ig (same clone as 66220-1-PBS)

    IF Staining of human tonsillitis using 66220-1-Ig (same clone as 66220-1-PBS)

    Immunofluorescent analysis of (4% PFA) fixed human tonsillitis tissue using PD-1/CD279 mouse mAb (66220-1-Ig) at dilution of 1:50 and CD20 rabbit pAb (24828-1-AP) at dilution of 1:50, further stained with Alexa Fluor 488-conjugated AffiniPure Goat Anti-Mouse IgG(H+L) for 66220-1-Ig, and Alexa Fluor 594-conjugated AffiniPure Goat Anti-Rabbit IgG (H+L) for 24828-1-AP. This data was developed using the same antibody clone with 66220-1-PBS in a different storage buffer formulation.

  • IF Staining of human tonsillitis using 66220-1-Ig (same clone as 66220-1-PBS)

    IF Staining of human tonsillitis using 66220-1-Ig (same clone as 66220-1-PBS)

    Immunofluorescent analysis of (4% PFA) fixed human tonsillitis tissue using PD-1/CD279 antibody (66220-1-Ig, Clone: 4H4D1 ) at dilution of 1:400 and CoraLite®488-Conjugated AffiniPure Goat Anti-Mouse IgG(H+L). This data was developed using the same antibody clone with 66220-1-PBS in a different storage buffer formulation.

背景介绍

Programmed cell death 1 (PD-1, also known as CD279) is an immunoinhibitory receptor that belongs to the CD28/CTLA-4 subfamily of the Ig superfamily. It is a 288 amino acid (aa) type I transmembrane protein composed of one Ig superfamily domain, a stalk, a transmembrane domain, and an intracellular domain containing an immunoreceptor tyrosine-based inhibitory motif (ITIM) as well as an immunoreceptor tyrosine-based switch motif (ITSM) (PMID: 18173375). PD-1 is expressed during thymic development and is induced in a variety of hematopoietic cells in the periphery by antigen receptor signaling and cytokines (PMID: 20636820). Engagement of PD-1 by its ligands PD-L1 or PD-L2 transduces a signal that inhibits T-cell proliferation, cytokine production, and cytolytic function (PMID: 19426218). It is critical for the regulation of T cell function during immunity and tolerance. Blockade of PD-1 can overcome immune resistance and also has been shown to have antitumor activity (PMID: 22658127; 23169436). The calculated molecular weight of PD-1 is 32 kDa. It has been reported that PD-1 is heavily glycosylated and migrates with an apparent molecular mass of 47-55 kDa on SDS-PAGE (PMID: 8671665; 17640856; 17003438).
