Peptone, Whey Protein Hydrolysate | 250g


Derived from whey protein concentrate, it has an exceptional amino nitrogen base and a well-balanced AA distribution. 

The premium nitrogen source for most microorganisms, ideal for general culture purposes, is best suited for high/fast yield protein expression media (such as TB, YPD, etc.).


This is a new product, we are just starting trial production, and have less stock, please enquire via support@gmexpression.com before ordering. Thank you.


Whey protein is very rare, only ~7g per 1kg of milk,  and its components include α-lactalbumin, β-lactoglobulin, serum albumin, immunoglobulin, and a small amount of lactoferrin. Whey protein concentrate is a by-product of the cheese-making process. It contains a fair amount of protein (80~85%) and a small amount of fat, as well as trace amounts of lactose, vitamins and minerals.


This GMES-exclusive product is made from whey protein concentrate purified by GMES's unique technology through protease enzymatic digestion, acid hydrolysis, desalting and vacuum powdering.

- No endogenous microbial growth inhibitors (e.g. lactotransferrin or antibacterial peptides).

- No exogenous antibiotics, functional small molecule impurities.

- Amino nitrogen content(~12%) is 3 to 4 times that of conventional peptones.

- Uniform distribution of amino acids

- Excellent solubility in water/non-polar solvents

- Nitrogen source in the form of amino acids and a trace of short peptides, without long chain peptides; ideal for absorption and utilisation by micro-organisms, which can significantly reduce the lag time in bacterial cultivation.
