  • Application notes
    Is unsuitable for ICC or IP.
  • Target

    • Function
      Serum albumin, the main protein of plasma, has a good binding capacity for water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs. Its main function is the regulation of the colloidal osmotic pressure of blood. Major zinc transporter in plasma, typically binds about 80% of all plasma zinc.
    • Tissue specificity
    • Involvement in disease
      Defects in ALB are a cause of familial dysalbuminemic hyperthyroxinemia (FDH) [MIM:103600]. FDH is a form of euthyroid hyperthyroxinemia that is due to increased affinity of ALB for T(4). It is the most common cause of inherited euthyroid hyperthyroxinemia in Caucasian population.
    • Sequence similarities
      Belongs to the ALB/AFP/VDB family.
      Contains 3 albumin domains.
    • Post-translational
      Kenitra variant is partially O-glycosylated at Thr-620. It has two new disulfide bonds Cys-600 to Cys-602 and Cys-601 to Cys-606.
      Glycated in diabetic patients.
      Phosphorylation sites are present in the extracelllular medium.
      Acetylated on Lys-223 by acetylsalicylic acid.
    • Cellular localization
    • Information by UniProt
    • Database links
    • Form
      There are 2 isoforms produced by alternative splicing.

    Thank you for contacting us.

    We are happy to help customers find the most suitable products for their research purposes; however we are not specialized in this particular field and do not want to recommend a product that may be unsuitable. I have done a precursory search and found two products guaranteed in ICC/IF which may suit your needs. These products are:ab41898 Anti-HNF4 antibody [K9218] (https://www.abcam.com/HNF4-antibody-K9218-ChIP-Grade-ab41898.html) and ab59118Anti-TCF2 antibody (https://www.abcam.com/TCF2-antibody-ab59118.html). While these may be good alternatives we encourage customers to consult the latest literature available through PubMed and other resources in order to find the most up-to-date information about their specific research interests.

    I am sorry that I could not be more helpful, but I hope that the available literature in this area can provide some clarification. Please do not hesitate to contact us again with other needs or with any questions about our products.
