Our SARS-CoV-2 Delta Variant Antigens
To support the research, development and validation of diagnostics and vaccines, we now offer trimeric whole Spike and RBD antigens for the SARS-CoV-2 B.1.617.2 (Delta) variant.
Our Delta Reagents
The Native Antigen Company now offers two Spike antigens for the SARS-CoV-2 Delta variant:
- Our trimeric whole spike antigen (B.1.671.2; AY.1, AY.2, AY.3) is stabilised as a pre-fusion trimer via six amino acid (HexaPro) changes in the S2 subunit, alongside a GSAS mutation in the furin cleavage site and a His-2xStrep-tag at the C-terminus for ease of purification.
- Our Spike (B.1.671.2) receptor-binding domain (RBD) antigen includes residues 319-542 of the full Spike sequence and a C-terminal His-tag for ease of purification.
These antigens are available in 100μg and 500μg sizes, as well as bulk supply of multiple grams.
Produced from our VirtuE™ expression system, our Spike antigens exhibit full glycosylation and proper folding, ideal for developing high quality immunoassays and raising highly specific antibodies.
