There existed a proper ratio of SA to complemented neutral lipids which facilitated the maximum binding of ribosomes. Increasing the subphase pH value will enhance the adsorption of ribosome, but when raising the subphase concentrations of K<sup>+</sup>, Mg<sup>2+</sup> and glycerol, the adsorption of ribosomes can be weakened, suggesting that the driving forces of the adsorption mainly come from the electrostatic interactions between the ribosome and the lipids.
