Removing N-linked oligosaccharides to aid protein crystallisation
Removing N-linked oligosaccharides to aid protein crystallisation A client was looking to solve the crystal structure of a secreted protein which contained a number of disulphide bonds and potential N-linked glycosylation sites, which leads to the attachment of complex sugar molecules. There was already literature available describing the [...]
Time critical purification of multiple Fab constructs for assay
Time critical purification of multiple Fab constructs for assay As a leading protein purification company, BiVictriX required us to develop a method to purify 10mg each of 24 different antibody-binding fragments (Fabs) to be tested in assays. Once analysed by BiVictriX, a smaller number of chosen constructs were to [...]
Adapting use of size exclusion chromatography to improve yields of an unstable, purified protein
Adapting use of size exclusion chromatography to improve yields of an unstable, purified protein A client asked us to express and purify at least 2 mg each of two similar enzymes for selectivity assays. There was literature precedent for both proteins, and a similar approach would be taken with [...]
