Product Information
Description: Casein is a phosphorus-containing complex protein with α-casein and β-casein as its main components. Casein is an orally active phosphoprotein that can be separated into various electrophoretic components, such as α2-Casein, κ-Casein, β-casein, and γ-casein. Casein can be used in biochemical research, to formulate biological culture media, and as a thickener, emulsifier and stabiliser.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
