Proteins purification
The PPP Unit counts with a laboratory perfectly equipped for the purification of recombinant proteins. The protein purification procedure is carried out according the protein characteristics and customers‘ needs.
Design: identification of the most appropriate strategy for protein purification, given the physical and chemical properties, opting either for purification modules or, in the case of fusion proteins, elements which enable purification by affinity.
Protein purification: downstream processing using FPLC chromatography and/or tangential filtration either from the cellular pellet or the supernatant when the protein is secreted. When necessary, the purification is performed through solubilization of inclusion bodies or by purification under denaturing conditions with later refolding.
Final product: the purified protein is delivered in the buffer, temperature and the concentration requested by the costumer. When demanded, the protein can be delivered in lyophilised form.
Quality control: the purified recombinant protein is analysed in terms of molecular weight, purity by SDS-PAGE, aggregation by DLS and identification by Peptide-Mass Fingerprinting. Additional analysis can be performed under customer’s agreement such as buffer optimization (Microdyalisis) or freeze-thaw stability.
Customer benefits
The service is completely personalised to ensure that the final product matches the intended use in terms of format, purity and activity. We have various purification methodologies to address specific needs, offering a wide range of possibilities for obtaining the final product. All services adhere to standardised procedures, guaranteeing the quality of the end product. Thus, instead of offering a generic solution, we deliver a customised product with the exact specifications requested by the customer.
Target customer
The PPP Unit extends its services across the scientific community, serving both private and public research organizations. This includes support for research centres, universities, hospitals, and companies in the sector. Leveraging our connection with the university, the PPP unit also provides specialised courses as part of the official master’s degrees and PhD programs at UAB.
