Description

Application

CaseiNSBlock alkaline treated casein is developed for use in immunoassay to remove non-specific binding and to reduce background. It is suitable for manufacturing of immunoassay buffers due to improved solubility in biological matrices compared to other forms of casein. Provides excellent blocking on all membranes and plates.

Biochem/physiol Actions

Partial gastrointestinal digestion of casein is a rich source of bioactive peptides, such as β-casomorphin. However, bovine casein is not homogeneous; variants A1 and B do lead to production of β-casomorphin 7 production, while A2 does not.

Preparation Note

Alkaline treated casein formulated to remove nonspecific binding in immunoassays
