RE: Does Innova detect Delta?30 Jun 2021 19:26
Yeah I thought I corrected myself about the spike.
This article mentions the N changes, which the Innova document says might make the test less effective
"Other mutations in Delta could help it thwart immunity. Some alter the spike's N-terminal domain (NTD), which protrudes from the protein's surface. A recent Cell paper identified one spot in the NTD as a “supersite,” unfailingly targeted by “ultra-potent” neutralizing antibodies from recovered patients. Delta's unique mutations delete the amino acids at positions 156 and 157 in the supersite and changes the 158th amino acid from arginine to glycine; the latter eliminates a direct contact point for antibody binding, says David Ostrov, a structural biologist at the University of Florida. “We think the 157/158 mutation is one of the hallmark mutations in Delta that has given it this more immune-evasion phenotype,” concurs Trevor Bedford, a computational biologist at the Fred Hutchinson Cancer Research Center."
