  • 免疫原

    Synthetic peptide derived from a region of human ZAP70 that contains tyrosine 292 (unfortunately, the amino acid sequence is considered to be commercially sensitive)

  • 阳性对照
    • Jurkat cells treated with hydrogen peroxide.
  • 常规说明Centrifuge before opening to settle contents.


  • 形式Liquid
  • 存放说明Shipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C or -80°C. Avoid freeze / thaw cycle.
  • 存储溶液Preservative: 0.05% Sodium Azide
    Constituents: Dulbecco's PBS without magnesium and calcium, 50% Glycerol, PBS, 1mg/ml BSA, pH 7.3
  • Concentration information loading...
  • 纯度Immunogen affinity purified
  • 纯化说明The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated ZAP70. The final product is generated by affinity chromatography using a ZAP70-derived peptide that is phosphorylated at threonine 292.

应用 Ab评论 说明
WB 1/1000. Predicted molecular weight: 74.3 kDa.


  • 功能Plays a role in T-cell development and lymphocyte activation. Essential for TCR-mediated IL-2 production. Isoform 1 induces TCR-mediated signal transduction, isoform 2 does not.
  • 组织特异性Expressed in T- and natural killer cells.
  • 疾病相关Defects in ZAP70 are the cause of selective T-cell defect (STD) [MIM:176947]. STD is an autosomal recessive form of severe combined immunodeficiency characterized by a selective absence of CD8-type T-cells.
  • 序列相似性Belongs to the protein kinase superfamily. Tyr protein kinase family. SYK/ZAP-70 subfamily.
    Contains 1 protein kinase domain.
    Contains 2 SH2 domains.
  • 结构域The SH2 domains bind to the phosphorylated tyrosine-based activation motif (TAM) of CD3Z and the non-canonical phosphorylated tyrosine-based activation motif (TAM) of RHOH.
  • 翻译后修饰Phosphorylated on tyrosine residues upon T-cell antigen receptor (TCR) stimulation. Tyr-319 phosphorylation is essential for full activity.
  • 细胞定位Cytoplasm. Cell membrane. After antigen stimulation, isoform 1 concentrates at the immunological synapse and isoform 2 remains cytoplasmic. Co-localizes together with RHOH in the immunological synapse. RHOH is required for its proper localization to the cell membrane and cytoskeleton fractions in the thymocytes.

  • Predicted band size : 74.3 kDa

    Peptide Competition and Phosphatase Treatment: Lysates prepared from Jurkat cells left untreated (1) or treated with hydrogen peroxide (2-6) were either left untreated (1-5) or treated with lambda phosphatase (6). Lysates were then incubated with ab12868 following prior incubation with: no peptide (1, 6), the non-phosphopeptide corresponding to the immunogen (2), a generic phosphotyrosine-containing peptide (4) or, the phosphopeptide immunogen (5). The data show that only the peptide corresponding to ZAP70 [phospho Y292] blocks the antibody signal. The data also show that phosphatase stripping eliminates the signal, verifying that the antibody is phospho-specific.
