Lambda Spike Products
The Native Antigen Company now offers two Spike antigens for the SARS-CoV-2 Delta variant:
- Our trimeric whole Spike antigen is stabilised as a pre-fusion trimer via six amino acid (HexaPro) changes in the S2 subunit, in addition to a GSAS mutation in the furin cleavage site and a His-2xStrep-tag at the C-terminus for ease of purification.
- Our Spike 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 with our VirtuE™ expression system, our Spike antigens exhibit full glycosylation and proper folding, ideal for developing high quality immunoassays and raising highly specific antibodies.
