Fig. 5: B cell ELISPOT was used to measure the gp120-specific memory B cell responses in DP6-001 volunteers.

A mixture of five autologous gp120 proteins same as used in DP6-01 vaccine was coated on the plates. a ELISPOT readouts in duplicate from one volunteer sample collected at different time points of vaccination course are shown. b The dynamics of gp120-specific memory B cell responses is shown as the group average in spot/1 million cells with standard error.
