Provitro provides one of the widest ranges of recombinant proteins produced in E. coli, insect cells and various mammalian cell types. To give you the most active proteins, we subcontracted qualified suppliers with many years of experience in producing bacterial and mammalian-derived recombinant proteins, and established an in-house quality control. Most of our proteins are delivered without carrier proteins or other additives, because we respect the wishes of our customers who prefer preparations without such compounds. Some products require additives, such as buffer, salts or protein, for their long-term stability. Therefore, we advise you to read our instructions providing reconstitution information for easier handling and use carefully. In general, our cytokines, chemokines and growth factors exceed purity of 95%. They are characterized by SDS-PAGE analysis and exhibit very high activity levels approved by WHO-standardised cell test systems, if applicable. We are sure to meet your needs and expectations when ordering our cytokines, chemokines or growth factor products.
