  • 描述
    兔多克隆抗体to Phosphoserine (HRP)
  • 宿主
  • 偶联物
  • 特异性
    Specifically recognizes both free-phosphoserine, serine-phosphorylated peptide and proteins. Does not cross-react with ATP, phosphotyrosine, peptidyl phosphothreonine and serine. Has slight cross-reactivity with free phosphothreonine. Readily reacts to known phosphoproteins such as phosvitin and alpha casein.

    BSA and KLH-phosphoserine conjugates.

  • 阳性对照
    • Use Mouse brain extract for Western Blotting or synthetic phosphopeptide or phosvitin for ELISA.



Our Abpromise guarantee covers the use of ab9334 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
WB Use a concentration of 2 µg/ml. To block use 3%BSA with 0.1% gelatin (do not use milk). We recommend that the antibody solution should contain 0.5% BSA to prevent non-specific binding.
ELISA Use a concentration of 1 µg/ml.


  • 相关性
    Changes in the serine/threonine phosphorylation state of a protein in response to various external stimuli can have profound effects on cellular signal transduction, apoptosis and carcinogenesis. The reagents, including phosphorylated protein/peptides, antibodies against the phosphospecific amino acid, are important tools to explore the activation of serine, threonine or tyrosine containing proteins. An aberrant protein phosphorylation is a hallmark of human disease, and the enzymes, particularly protein kinases, which control protein phosphorylation are recognized as a major new drug target family.
