Variant Spike Proteins – Alpha, Beta, Delta, Gamma, B1.617

Isolated Spike Proteins from COVID-19 are available from Biorbyt, manufactured on a proprietary mammalian protein expression platform. The technology focusses on codon optimization and the stable expression of large molecular weight proteins.

Uniquely expressed large MW proteins with extensive post-translational modifications via codon optimised sequences in proprietary expression plasmids.

Super stable trimeric Spikes as abundant capture antigens ensuring the most faithful detection of circulating specific anti-SARS-CoV-2 antibodies in recovered or vaccinated people.
