Amoeba proteus given adequate food grows exponentially and clones of amoebae are normally immortal. After periods of food supply restriction to that necessary for maintenance, or food intake restriction by agitation, cells subsequently given a normal

Clones of amoebae which are normally “immortal” can be given a defined life span. By exchanging nuclei between normal and spanned clones, we have shown that factors conveying the “spanning” characteristic are associated with both nucleus and

A specific method of staining certain groups in proteins for examination in the light microscope has been developed for electron microscopy. The compound DNFB (1-fluoro-2:4-dinitrobenzene) reacts with NH2, SH and phenolic groups, and may be made in t

Studies have been made of the effect of acylation on various biological properties of the compounds NH 2 N(CH 2 CH 2 Cl) 2 and HO N(CH 2 CH 2 Cl) 2 . Acylation decreases the toxicity of the compounds to rats. The selective toxicity of the acylated de

A systematic approach to electrostatic membrane models is developed on the basis of biological evidence and surface chemical data. Applying the principles of electrostatics to chemical and physical models of bimolecular lipid membranes allows the eva

Suspensions of amoebae were treated with [3H]glucosamine either before or after exposure to solutions of KCl or Alcian blue. Several hours later, the cell surface was isolated. Comparison of specific activities of control and experimental material sh
