Relevance β-Lactoglobulin is the major whey protein of cow and sheep's milk (~3 g/l), and is also present in many other mammalian species; a notable exception being humans. Bovine β-lactoglobulin is a relatively small protein of 162 residues, with an 18.4 kDa molecular weight. In physiological conditions it is predominantly dimeric, but dissociates to a monomer below about pH 3. Nevertheless, its native state remains fairly intact at lower pH values, as determined using NMR.

Q&A and Customer Reviews


I am inquiring about the following product:
Can you let me know:
The stated purity is >95%, does it contain alpha- lactoglobin? if so, do you know the ratio of alpha/beta?
Is the protein supplied in liquid or lyophilized?

Very nice to receive your inquiry. The product details are as below.
Code: CSB-NP002801B
Name: Bovine milk β-Lactoglobulin
Size: 100mg
The product will be provided in liquid form, and the storage buffer is PBS.
This is a native protein. We could separate the alpha and beta types, and extract beta-lactoglobulin.
However beta-lactoglobulin contains A type and B type. The protein we extract is the mixture of A type and B type of beta-lactoglobulin.
