"casein, as practised by Hammarsten, consists in treating milk with acetic acid, and dissolving the precipitate in dilute ammonia or sodium carbonate, an alkaline reaction being guarded against.


Insoluble casein micelles also create an obstacle for purification instruments to operate efficiently. The conventional method, to precipitate caseins by lowering pH to 4.6 and then recover the whey fraction for further purification using chromatography techniques, is not applicable to proteins having an isoelectric point similar to caseins.

Blocking solution: 0.5% Hammersten casein, 0.05% Tween-20 in PBS. Heat on stir plate until casein is dissolved. This should occur at about 90 °Celsius.

Hammarsten method casein

Depending on the method of manufacture. casein is classified as rennet casein or acid casein. hemoglobin and casein is 2.0 and 2.5, re- spectively.

The solution temperature is gradually increased with gentle stirring to 80-85 °C for about 10 minutes until a homogenous dispersion is achieved. Do not to boil the solution.

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.
