Figure Lengend Snippet: mice vaccination and antibody induction. (A) mice groups. Mice were divided into 4 groups with 15 mice in each group. Mice vaccinated with DPBS were used as negative control. (B) mice vaccination and samples collection. LNP-mRNA was administered intramuscularly at day 0 and 14. Blood was collected at day 7, 13, and 35. One group of mice was sacrificed at day 30 to collect the spleens. Mice were intranasally challenged with a lethal dose (1×10 6 pfu) of WR vaccinia virus. (C and D) A35R and M1R specific total IgGs, respectively. Serum with different dilutions at different timepoints was used for ELISA against A35R or M1R. (E) Neutralizing antibodies were measured. The sera were diluted and incubated with the virus for PRNT. Serum from DPBS group were regarded as 0% neutralization.
Article Snippet: A35R protein (OkayBio, C1620) and M1R protein (OkayBio, C1624) were diluted to 5 μg/ ml by ELISA coating buffer (Elabscience, E-ELIR-003) and added into 96-well plates for overnight coating at 4 degree.
