Description			Found in human plasma in concentrations of 55-140mg/100ml. Classical standard glycoprotein for studies on the structure of the oligosaccharide units. Carbohydrate content is 40%. Its biological significance is unknown although it can bind progesterone 15 times as strongly as albumin. Sialic-acid-deficient alpha-1-AG has an affinity for vitamin B-12. Clinically, alpha 1 acid glycoprotein is an acute-phase reactant that together with haptoglobin is an indicator of acute inflammation. The alpha 1 acid glycoprotein: haptoglobin ratio is useful in studies of bone marrow disorders, hemolytic processes and metastases. Source: Alpha 1 Acid Glycoprotein, from Human Plasma Molecular Weight: ~49kD Biological Activity: ≥120units/mg protein. Unit Definition: One unit is defined as the amount of enzyme which will hydrolyze one umole of N-tosyl-L-arginine methyl ester in 30 minutes at 37°C at pH 8.0. Storage and Stability: Lyophilized powder may be stored at -20°C. Reconstitute with sterile buffer or ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
