THE PROTEIN EXPRESSION EXPERTS
Using bacterial, yeast, insect and mammalian expression systems, SB has produced over 200 recombinant proteins covering a wide range of targets including enzymes, membrane proteins, and antibodies.
Our knowledgeable team will work with you to determine the right expression system and purification protocol to suit your needs. Our standard, 3-step purification protocol routinely provides purity > 85%, with further purification steps yielding purity > 95%.
As standard, we run a small scale pilot to confirm expression and determine yield, allowing us to accurately scale up to achieve the desired quantity of protein.
Whether you require our full expression service from cloning to large scale purification or you simply need to purify your target from paste, you can trust SB to deliver. With turnaround times as little as 2 weeks and single batch capacity up to 200L, we have the expertise to accommodate your requirements.
All proteins are supplied with a report including coomassie stained SDS-PAGE gel images and yield estimation. N-terminal sequencing, NMR and mass spec can also be provided if required). To ensure complete satisfaction, our QC steps can be designed to include a range of assays to confirm enzyme activity or ligand-binding capability.
From cloning to large scale expression and purification, trust SB to deliver every time.
