B.1.1.529 Lineage / Omicron Lineage

Background B.1.1.529: The South African Institute of Infectious Diseases NICD said Thursday, Nov. 25, 2021, that 22 cases of the new variant B.1.1.529 (Omicron) have been detected in South Africa. The World Health Organization (WHO) is already investigating whether B.1.1.529 should be classified as a concern. Researchers spotted B.1.1.529 in genome-sequencing data from Botswana. The variant stood out because it contains more than 30 changes to the spike protein — the SARS-CoV-2 protein that recognizes host cells and is the main target of the body’s immune responses. Many of the changes have been found in variants such as Delta and Alpha and are linked to heightened infectivity and the ability to evade infection-blocking antibodies.

SARS-CoV-2 omicron lineage is made up of several sublineages, including BA.1 and BA.2, all of which are being monitored by WHO. As of 22.02 the BA.2 virus variant is considered a variant of concern. BA.2 is among the most common, with reported sequences increasing in recent weeks, relative to BA.1, though global circulation of all variants is currently declining. BA.2 differs from BA.1 in its genetic sequence, including some amino acid differences in the spike protein and other proteins. Studies have shown that BA.2 has a growth advantage over BA.1.

B.1.526 Lineage / Iota Lineage

Background B.1.526: The variant that Ho’s team identified in New York, also known as B.1.526, carries a notorious mutation called E484K that has been found in variants identified in South Africa and Brazil. Studies by multiple labs have shown that the E484K change — which is in a portion of the coronavirus spike protein that recognizes host cells — weakens the potency of antibodies that can ordinarily disable the virus.7

Mutations: T95I, D253G, L5F, D253G, E484K, D614G, A701V with a smaller fraction having S477N instead of E484K.1

B.1.640.2 Variant

Background B.1.640.2: The B.1.640.2 variant was first identified in October and uploaded to Gisaid, a database for disease variants, on Nov. 4. Abdi Mahmud, a Covid incident manager with the W.H.O., told reporters in Geneva on Tuesday that the variant had been on the agency’s radar since November, but added that it did not appear to have spread widely over the past two months.1

Mutations: 46 mutations and 37 deletions resulting in 30 amino acid substitutions and 12 deletions. Fourteen amino acid substitutions, including N501Y and E484K, and 9 deletions are located in the spike protein.

CR3022 not affected by B.1.1.529 / omicron Variant Mutations

One of the looming questions regarding newly emerging variants of SARS-CoV-2 is, whether existing antibody based assays and pharmaceuticals remain useable. In collaboration with Nanotemper we measured the affinity of our S protein RBD antibody CR3022 (ABIN6952546) to the canonical trimeric SARS-CoV-2 S protein and those of the variants of concern B.1.1.7 / alpha, B.1.351 / beta, B.1.617.2 / delta, B.1.617.1 / kappa and P.1 / gamma by microscale thermophoresis (MST). In a second iteration we acknowledged the dominant B.1.1.529 / omicron variant and extended the antibody selection with neutralizing antibodies MM43 (ABIN7036075) and MM117 (ABIN7042145). Discover the results down below.
