Development of a new sandwich ELISA for the detection of bovine A1 beta-casein. [PDF]

PLoS ONE
The bovine genetic variant A2 beta-casein is associated with fewer digestive and absorption issues compared to A1 beta-casein, leading to increased global demand for A2 milk.

Differential Release of β-Casomorphins from A1 and A2 Milk During Standardized Gastrointestinal Digestion Quantified by CE–MS [PDF]

Foods
β-Casein A1 and A2 (β-CN-A1 and β-CN-A2) are the two predominant β-CN proteoforms in bovine milk. β-CN-A1 has been associated with a greater propensity to release opioid peptides, such as β-casomorphin-7 (β-CM-7) and β-casomorphin-5 (β-CM-5), during ...

An ARMS-integrated high-resolution melting assay for reliable discrimination of the A1/A2 polymorphism in the bovine CSN2 gene [PDF]

Food Chemistry: Molecular Sciences
Practical, rapid, and cost-efficient screening tools are needed to verify A2 milk purity and support selective breeding programs. Although several genotyping methods are available, their routine implementation is often limited by equipment costs and ...

A Narrative Review: A1 and A2 Milk Beta Caseins Effect on Gut Microbiota [PDF]

Nutrients
Background/Objectives: The composition and function of gut microbiome is significantly influenced by dietary factors. Growing evidence suggests that A1-type and A2-type beta casein (β-CN) may exert distinct effects on the gut environment, with implications for digestive discomfort and broader health outcomes.

Effects of β-casein A1/A2 milk and β- and κ-casein genotypes on the performance, body composition, and fecal score of dairy calves [PDF]

Scientific Reports
The perceived health benefits of β-casein (β-CN) A2 milk for humans have driven increased selection for homozygous β-CN A2 dairy cattle. However, little is known about the effects of feeding milk with different β-CN variants to calves, or about the ...

Frequency of A1 and A2 alleles of the β-casein gene in cattle in the Cajamarca region of Peru [PDF]

Open Veterinary Journal
Background: Cow's milk β-casein has multiple genetic variants, the two most common of which are A1 and A2, which are encoded by the CSN2 gene. Evidence suggests that the A1 variant may negatively affect human health.

A2 Bovine Milk and Caprine Milk as a Means of Remedy for Milk Protein Allergy

Dairy, 2021
A new type of cow’s milk, called A2 milk, has appeared in the dairy aisles of supermarkets in recent years. Cows’ milk generally contains two major types of beta-casein as A1 and A2 types, although there are 13 genetic variants of β-casein: A1, A2, A3 ...

Difference between A1 and A2 milk: Risk of A1 milk

, 2022
Milk is a primary source of nutrition for infants after the birth and also for human beings. Generally, milk is either from humans (women) or from cattle origin they contain various types of proteins, vitamins, minerals and so on. Components in milk show various beneficial actions in beings and some of the studies found that metabolites of it show ...
