GeneTex continues to expand and validate its comprehensive catalog of outstanding antibodies and reagents for SARS-CoV-2 (COVID-19) research. This includes ongoing assessment of our antibodies’ ability to detect important viral variants, particularly the WHO-designated Variants of Concern (VOCs). For more information, please see Tables 1-2 below.
In GeneTex’s SARS-CoV-2 spike antibody portfolio, the anti-spike RBD [HL1014] and anti-spike S1 [HL13402] recombinant rabbit clones exhibit high affinity for all SARS-CoV-2 spike proteins, including those of the B.1.1.7 (Alpha), B.1.351 (Beta), P.1 (Gamma), and B.1.617.2 (Delta) variants (Table 1). Clone [HL13402] also performs exceptionally well when paired with the widely published mouse clone [1A9] (against the S2 subunit) for sandwich ELISA.
GeneTex’s recombinant rabbit nucleocapsid antibodies display high affinity for the WIV04/2019 (reference sequence) human cell-expressed full-length SARS-CoV-2 nucleocapsid protein, with EC50 values ranging from 0.006-0.074 nM. Importantly, one matched nucleocapsid antibody pair (i.e., GTX635689 and GTX635686) demonstrates superior sensitivity in sandwich ELISA and lateral flow assays. This pair also recognizes the nucleocapsid protein of the B.1.617.2 (Delta) variant, as do several other individual recombinant clones (Table 2).
Taken together, GeneTex’s large selection of SARS-CoV-2 antibodies virtually guarantees that you will find a reagent appropriate for your desired application.
Table 1. SARS-CoV-2 Variant Detection by GeneTex Spike Antibody Clones
