A-Z> Solutions for COVID-19 vaccine safety and immunogenicity evaluation
Researchers around the world are working hard on a vaccine for COVID-19. Up until now, several vaccine candidates have entered into phase III clinical trials. Experts estimate that a fast-tracked vaccine development process could potentially bring a successful candidate to market within one year or even less. In the development of a COVID-19 vaccine, safety and immunogenicity evaluation are indispensable and well-established assays are required for fast and convenient assessment of the vaccine candidates.
Based on advanced technology platform in recombinant protein production, ACROBiosystems has developed a series of critical reagents for COVID-19 vaccine development and evaluation, including recombinant proteins, antibodies and ELISA kits. These featured products are suitable for IgG/M antibody titer detection, neutralizing antibody titer detection and antigen titer detection to accelerate the vaccine development.
> Cat.No. SPN-C52H9 Product: SARS-CoV-2 S protein, His Tag, Super stable trimer (MALS & NS-EM verified)
Fig 1. The purity of SARS-CoV-2 S protein, His Tag, Super stable trimer (Cat. No. SPN-C52H9) was more than 90% verified by SDS-PAGE under reducing (R) condition. The molecular weight was around 550-660 kDa confirmed by SEC-MALS. The particles are similar in size and appearance to SARS-CoV-2 trimers reported in published literature verified by negative stain electron micrography.
