Description
Albumins are monomeric proteins found in body fluids and tissues. Human serum albumin (HSA) is the most abundant protein in human blood plasma with a molecular weight of about 66.5 kDa. The major biological function of albumin is to regulate the colloidal osmotic blood pressure. In addition, albumin acts as carrier protein for hormones, fatty acids and other compounds, and buffers pH. The reference range for albumin concentration in serum is approximately 35-50 g/L.
Application & Characteristics
Due to free hydrophobic regions albumins are used to solubilize lipids and stabilize other proteins such as e.g. growth factors in tissue culture applications. They are also used as blocking agents in Western blots or ELISA applications and as a protein standard. Albumin has a low molecular weight, is easily soluble in water and contains an excess of acidic amino acids.
