Can this product be used to culture cells other than bovine species?
Yes! We have seen our products used successfully in a variety of cell cultures across land-dwelling and aquatic species.
What is the concentration of recombinant Albumin in this product?
All Ento- products are a very complex mixture of biomolecules which are enriched in the protein(s) of interest (recombinant bovine FGF-2, in this case). Due to this complexity, the protein(s) of interest's actual concentration is exceedingly difficult to quantify. To suggest initial working quantities, we reference Ento- products with a metric we refer to as "functional equivalence" which is based on our in-house assays. Functional equivalence is the equivalent amount of isolated protein of interest that is needed to replicate the performance of this product.
This product is rigorously tested to ensure that both the background molecular profile of the supplement and the protein of interest contribute beneficial effects to cell growth and pass all safety testing requirements.
Has any safety testing been performed for this product?
Please see above for an example CoA which describes our safety testing results.
Are volume discounts available for this product?
Yes. Please reach out to firstname.lastname@example.org to discuss your needs.
