Yes, for the E. coli expression system, we are able to produce large quantities of proteins (up to the gram level) in one batch. For these large-scale projects, we usually start with small-scale protein expression and purification, and if the small-scale results meet the customer's needs, we can continue to scale up the experiment. Depending on the customer's needs and protein expression, Beta Lifescience's labs can produce proteins in the milligram to gram scale for both research and industrial customers.
