Samples of NGL COVID-19 Spike Protein Affinity resin are immediately available as loose resin or pre-packed in Repligen OPUS^® Columns.

Target applications include purification of SARs CoV-2 spike protein variants containing the RBD such as S protein (S1/S2), S1 Protein, RBD, and S Protein Trimer. Development data suggest that purification of whole inactivated virus, virus like particles (VLPs), or adenovirus may not yield satisfactory results.

OPUS^® Columns allow you to progress from development to manufacturing scale in weeks, using pre-packed and pre-qualified chromatography columns.
