A1 β-casein and A2 β-casein: effects on the gastrointestinal motility, digestion, and absorption

Journal of Functional Foods
This study compared A1 and A2 β-casein using a constipated mouse model and ex vivo intestinal sac assays. A2 β-casein significantly improved constipation-related outcomes—enhancing body weight recovery, shortening the first black stool time, increasing ...

Genotypic profiling of A1 and A2 β-casein alleles in Punganur cattle using PCR-RFLP

Indian Journal of Animal Sciences
Milk is regarded as nature’s perfect food due to the presence of essential nutrients required for the growth and development of mammals. The consumption of milk with a specific β casein variant either A1 or A2 had a relationship with the risk of ...

Determination of A1 and A2 β-casein in cow milk by high-performance liquid chromatography tandem mass spectrometry [PDF]

Journal of Dairy Science
: A2 β-CN milk has gained widespread acceptance due to its nutritional benefits. To verify the authenticity and detect adulteration and contamination in A2 milk, we developed an HPLC-MS/MS method for determining the characteristic peptides of A1 and A2 β-
