Background
Six proteins in milk are responsible for about 90% of the proteins present in milk (alphaS1 casein, alphaS2 casein, beta casein, kappa casein, alpha lactalbumin and beta lactoglobulin). Four of these are caseins, two of them are whey-proteins. This test for beta casein protein detects the beta casein A2 protein concentration in milk with regard to beta casein A1 and B.
Test specific information
We offer three versions of beta casein tests. Two are DNA-based (a simple one, test code R534, and an advanced version, test code R535), the third one quantitates the beta casein A2-protein in milk. The milk-based protein test is dedicated to confirm whether the A2 beta casein content is actually greater than 99% of the total beta casein protein in commercial milk.
Age
This test provides information on one or more milk components. The genetic constitution of an animal remains the same during life.
Throughput
Normally the result can be expected within 25 working days. This turn-around-time starts when both the sample and the fully filled-out and signed submission form have been received.
Location of disease or trait
Milk is present in the udder.
Breed dependence
For this test samples from all breeds are accepted.
Sample type
For this DNA test we accept the following materials: Milk. Please contact PharmaDNA if you wish to submit other material as listed.
Result
Milk quality is based on many genetic factors. For each factor, a separate test result will be returned.
Inheritance
Various genetic factors influencing milk quality are inherited in a dominant or recessive mode. Milk quality is influenced by a large number of genetic factors.
