Since the end of 2020, different SARS-CoV-2 variants have appeared worldwide − alpha (B.1.1.7), beta (B.1.351), gamma (P.1/B.1.1.128), delta (B1.617.2), and omicron (B.1.1.529) – which show differences in transmissibility as well as disease severity compared with the original virus. These variants are mainly defined by mutations in the spike protein, which are critical viral entry into human host cells. Genomax supplies a selection of SARS-CoV-2 ELISA kits and reagents that serve to help researchers quantify IgG antibodies against the SARS-CoV-2 Omicron or Delta spike variant proteins in human serum.

    – A semi-quantitative array displaying 22 important coronavirus spike (S) and nucleocapsid (N) proteins derived from SARS-CoV-2 (Covid-19) alpha to lambda variants, SARS-CoV, MERS-CoV, and HcoV-HKU1. It is suitable for antibody detection in serum, plasma, and other liquid sample types.

Featured Recombinant Proteins

Browse recombinant proteins from RayBiotech:

  • Recombinant SARS-CoV-2 Proteins – COVID-19 Proteins
  • SARS, MERS, and HKU1 Coronavirus Proteins
  • Thrombosis Proteins – Thrombosis, or blood clotting, obstructs blood flow through the circulatory system and can be caused by numerous factors. Inflammation associated with SARS-CoV-2 or COVID-19 infection can lead to a type of thrombosis called “disseminated intravascular coagulopathy” (DIC) that affects the lung, heart, or kidneys. DIC in COVID-19 patients initially presents with abnormalities in prothrombin time, partial thromboplastin time, and platelet counts. RayBiotech’s functional thrombosis proteins are ideal for developing coagulation assays to assist with DIC monitoring.

At each and every step of your workflow, we want to be able to disrupt and dismantle the SARS-CoV-2 virus. This means understanding the functions of the proteins encoded by the virus genome, and the host entry points and pathways it utilizes. It means discerning effective immune responses in COVID-19 patients and disease models. And it means discovering new biomarkers and pathways for therapeutic treatments, vaccine candidates, and viral detection kits. BioLegend supplies a diverse portfolio of products (antibodies, recombinant proteins, cytokine detection kits, and proteogenomics profiling options) by workflow stages, making it easier to pick your reagents and start your experiments.
