ACROBiosystems社 Pfizer & BioNTech published positive Phase 1/2 interim report of mRNA vaccine
Phase 1/2 interim report of Pfizer’s mRNA vaccine encoding trimerized SARS-CoV-2 spike glycoprotein RBD was published on medRxiv preprint recently. ACROBiosystems proudly supplies all functional COVID-19 antigens for IgG assay.
In the RBD-binding IgG assay, the biotinylated S protein RBD from ACROBiosystems Cat.No. SPD-C82E9）was bound to streptavidin-coated Luminex microspheres.
By employing the unique Avitag™ technology, ACROBiosystems developed a series of SARS-CoV-2 related biotinylated recombinant proteins which are in high purity and activity and perform good affinity. These biotinylated proteins are suitable in different applications of SARS-CoV-2 related drugs, vaccines and diagnostic test development.
Biotinylated Spike protein trimer and HEK 293 cells expressed Nucleocapsid protein are coming soon!
※ SDS-PAGE & SEC-MALS-High purity & homogeneity
Fig 1 The purity of Biotinylated SARS-CoV-2 S protein RBD, His,Avitag (Cat. No. SPD-C82E9) is greater than 90% verified by SDS-PAGE and SEC-MALS.
Fig 3 Loaded Biotinylated SARS-CoV-2 S protein RBD, His,Avitag (Cat. No. SPD-C82E9) on SA Biosensor, can bind Human ACE2, His Tag (Cat. No. AC2-H52H8) with an affinity constant of 5.86 nM as determined in BLI assay (ForteBio Octet Red96e).
Additionally, ACROBiosystems has also developed a series of antibody titer assay kits to accelerate the drug and vaccine research and development.
