Products from BPS Bioscience require a minimum order value above 400€

Encompassing Amino Acids: 16-1213

Description: Recombinant SARS-CoV-2 Spike protein in its homotrimeric form, containing S1+S2 subunits and encompassing amino acids 16-1213. This protein corresponds to SARS-CoV-2 Variant B.1.351, also known as variant Beta originally discovered in South Africa, and contains the nine known mutations listed below, in addition to deletion 242-244. It also contains mutations 682RRAR685>A, K986P and V987P. The construct has a C-terminal His-tag (6xHis). Note that the expected MW of the S1+S2 monomer is 137kDa but migrates at a higher MW in SDS-PAGE due to glycosylation. The recombinant protein was affinity purified.

*Deletion 242-244 is known as 241-243 in some databases and on the CDC website. This is the same deletion. As stated by Tegally et al., Nature 2021: "We also observe a deletion of three amino acids at positions 242 to 244, which was seen in samples extracted and generated in different laboratories across the NGS-SA. This region is difficult to align; the deletion could potentially also be located at positions 241 to 243, but the resulting sequence would be exactly the same. "
