General description

Lactalbumin hydrolysate is an enzymatic digest of Lactalbumin and contains high levels of essential amino acids. It is recommended for applications requiring a highly soluble source of amino acids and peptides. It is especially useful in fermentation, laboratory media, and in tissue culture. Lactalbumin, also called whey protein, is the milk albumin, and obtained from whey. There are alpha and beta lactalbumins which are both contained in milk. Owing to its high nutritional quality it can support the growth of numerous cell types like mammalian, insect, and bacterial.

Application

Lactalbumin hydrolysate can be used: -
In the production of recombinant proteins
As a supplement in mammalian cell culture media
As a substrate for growth of many microbes
