Anti-SARS-CoV-2 (B.1.1.529) Neutralizing Antibody Titer Serologic Assay Kit (Spike RBD) | RAS-N056| Gentaur Distribution US, UK & Europe
As of Nov 29th, confirmed cases of a new variant of concern (VOC) B.1.1.529 have been reported in South Africa, Botswana and more than 12 other countries. Thanks to the rapid sequencing efforts of South African scientists, the whole world is now alerted about this potentially devastating lineage, which was assigned the name Omicron by WHO.Omicron is a highly divergent variant with a high number of mutations (26-35) in the spike. Identification of some familiar mutations that also appeared on other VOCs gives rises to concerns of its immune escape potential and higher transmissibility. To facilitate the mutant-related research, drug trials and vaccine development, a high-throughput assay to measure neutralizing antibodies against the mutants is in urgent need.

Molecule: Spike RBD.
Format: Solid.
Species: SARSN/ACoVN/A2.
Application: This Kit is developed for qualitative detection or titer measurement of Anti-SARS-CoV-2 (B.1.1.529) neutralizing antibody (Spike RBD) in human serum.
Kit Component: This assay kit is used to measure the levels of Anti-SARS-CoV-2 neutralizing antibody through a competitive ELISA. The microplate in the kit has been pre-coated with Human ACE2 protein. First serum samples, Positive control, Negative Control are added to the wells followed by addition of HRP-SARS-CoV-2 Spike RBD. After incubation, the wells are washed and substrate is added to the wells. The reaction is terminated by the addition of stop solution and the intensity of color is measured at 450 nm. The presence of neutralizing antibodies in samples will compete with ACE2 for HRP-SARS-CoV-2 Spike RBD binding. The intensity of assay signal decrease proportionally to the presence of Anti-SARS-CoV-2 neutralizing antibody.
Stability: 1. Unopened kit should be stored at 2℃-8℃ upon receiving. 2. Find the expiration date on the outside packaging and do not use reagents past their expiration date. 3. The opened kit should be stored per components table. The shelf life is 30 days from the date of opening.
Storage Conditions: 2-8℃.
Shipping Conditions: RT
