Stabilized Delta Trimeric Spike Protein

Produced in CHO cells. Available in mg to grams.

The Delta variant of SARS-CoV-2 was first detected in India and has, by November 2021, spread to over 179 countries. It contains again the 614G mutations and others, notably a proline to arginine substitution that may facilitate the cleavage of the S precursor into the S1/S2 conversion, which results in the fusion of the spike protein with the cell membrane receptor ACE2.
