Rat Serum Albumin Protein, His Tag (MALS & SPR verified)

  • Synonym
    Serum albumin,ALB,Alb
  • Source
    Rat Serum Albumin, His Tag(RSA-R52H1) is expressed from human 293 cells (HEK293). It contains AA Glu 25 - Ala 608 (Accession # P02770 ).
    Predicted N-terminus: Glu 25
  • Molecular Characterization
    Serum Albumin Structure

    This protein carries a polyhistidine tag at the C-terminus

    The protein has a calculated MW of 67.8 kDa. The protein migrates as 64-68 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

    >95% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

  • Background
    serum albumin (SA) is also known as ALB, which is the main protein of plasma and has a good binding capacity for water,Ca2+,Na+,K+,fatty acids,hormones, bilirubin and drugs.The main function of SA is the regulation of the colloidal osmotic pressure of blood. As Major zinc transporter in plasma, SA typically binds about 80% of all plasma zinc. A variant structure of albumin could lead to increased binding of zinc resulting in an asymptomatic augmentation of zinc concentration in the blood. Defects in serum albumin can cause familial dysalbuminemic hyperthyroxinemia which is a form of euthyroid hyperthyroxinemia that is due to increased affinity of serum albumin for T4. It is the most common cause of inherited euthyroid hyperthyroxinemia in Caucasian population.
