Beta-lactoglobulin

White goods white freeze-dried powder is a protein-based substance with a relative molecular mass ranging from 35,000 to 42,000. It contains β-lactoglobulin A and B, which can be effectively separated using chromatographic techniques. Both β1 and β2 components can be distinguished through agar electrophoresis. This powder is soluble in water and neutral sodium chloride solutions. Its isoelectric point (pI) lies between 5.1 and 5.2. The specific optical rotation [α]₂₅ᴰ is -30.4° in acetate buffer at pH 4.8 and ionic strength μ = 0.1. At a concentration of 1%, the absorbance at 280 nm (1 cm path length) is 9.3. This product is widely used in biochemical research, including the study of protein structure and function, organic molecular interactions, and as a non-glycoprotein molecular weight marker for SDS-PAGE. It also plays a key role in genetic and pathological studies, serving as a raw material for the preparation of genetic markers. For optimal storage, keep it at a temperature between 2°C and 8°C. Proper handling and storage are essential to maintain its stability and performance in various experimental applications. Whether you're conducting protein analysis or working on molecular biology projects, this powder offers a reliable and consistent reference for your research needs.
