From left to right: Stained protein ladder, GAS ATCC 19165, GAS 31009, GAS 50362, GGS ATCC 12394, GGS 5109.09, GGS 5804.
Although the sensitivity of immune cells to GAS or GGS supernatants is shown in the first section of the results, were any controls used in the neutralization assays with liposomes?
