This protocol will result in the accurate qualitative measurement of anti-Chikungunya virus antibody (Ab) from infected mouse tissue or serum. This assay was developed by Dr. Caitlin Briggs, Arbovax, Inc. Chikungunya is a BL3 agent and should be handled in a biosafety level 3 laboratory under BL3 conditions. This protocol was used in the publication “Chikungunya virus host range E2 transmembrane deletion mutants induce protective immunity against challenge in C57BL/6J mice” (Piper et al., 2013).
