The effect of α-conotoxins MII; PnIA; RgIA; [V11L,V16D]ArIB ([L,D]ArIB) and α-cobratoxin (CTX) at concentration of 1 nM on the viability (a) and on the proliferative activity (b) of C6 glioma cells after 24 h (n = 20), 48 h (n = 20), and 72 h (n = 10–12) of incubation. The cell viability and concentration were determined by flow cytometry. * p < 0.05 according to Student’s t-test when compared to control.
