[Effect of nonelectrolytes on the polymerization of G-actin]

The non-electrolytes--urea, thiourea, sucrose, glycerin, polyethylendioxid, glutaraldehyde--inhibit polymerization of G-actin in vitro. The results are discussed in association with the capability of some non-electrolytes preventing colloid reactions of alterated protoplasm and increasing the stability of cells to injuring agents.
