Development of a high-throughput opsonophagocytic assay for the determination of functional antibody activity against Streptococcus pyogenes using bioluminescence

J Microbiol Methods. 2017 Mar;134:58-61. doi: 10.1016/j.mimet.2017.01.010. Epub 2017 Jan 21.


The lack of standardised protocols for the assessment of functional antibodies has hindered Streptococcus pyogenes research and the development of vaccines. A robust, high throughput opsonophagocytic bactericidal assay to determine protective antibodies in human and rabbit serum has been developed that utilises bioluminescence as a rapid read out.

Keywords: Bactericidal assay; Bioluminescence; Correlates of protection; Group A Streptococcus (GAS); Lancefield assay; Protective antibodies.
