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

This test is performed by Analutos Ltd.

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.

Turnaround time

The Turnaround Time (TAT) depends on various factors, such as the shipment time of your sample to the test location, the test method(s) and whether the tests are performed completely or partially by a Partner Lab or Patent owner.

The TAT of tests performed at our facilities is normally 10 working days after receipt of the sample at the testing laboratory (VHL, VHP or Certagen). For tests performed by a Partner Laboratory (so-called "partner lab test") or patent owner, the TAT is at least 20 working days after receipt of your sample. Because the shipment time to our Partner Labs or patent owner may vary due to factors we cannot influence, the mentioned 20 working days are therefore an estimate.

PLEASE NOTE
Sometimes it is necessary to re-run your sample. We call this a retest. In that case, the TAT will of course be extended.

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 Dr. Van Haeringen Laboratorium 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.
