  • 機能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.
  • 組織特異性Plasma.
  • 関連疾患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.
  • 配列類似性Belongs to the ALB/AFP/VDB family.
    Contains 3 albumin domains.
  • 翻訳後修飾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.
  • 細胞内局在Secreted.

Thank you for contacting Abcam.

The ratio for this particular lot is 2.5 moles of biotin per mole of human albumin.
Please tell us if we can provide more help with this issue.

Thank you for contacting Abcam regarding ab8033.

I have confirmed with the laboratory that our target biotin to protein ratio is between 10-20 molecules of biotin to protein. I can provide more specific information for a particular lot....

Thank you for your enquiry. The exact biotin group added was Biotinamidocaproate N-Hydroxysuccinimide Ester. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Yes, you are correct. I am sorry if there was some confusion from my earlier response. ab8033 is not an antibody but rather biotin-labeled albumin. Yes, the molecule has been randomly labeled with biotin at Lys residues. Thank you for your enquir...

I have a response from our supplier and I want to thank you for your patience. The biotin is attached to the antibody via free primary amines, i.e. at Lys residues. If you have any further questions please do not hesitate to contact me.
