Abstract
BY suitable manipulation, it has been found possible to spread true monolayers of proteins on various substrates. These monolayers can be examined both in the Langmuir trough and by the method of surface potentials. In the course of an investigation on the properties of monolayers of myosin, it has been found that when this protein is spread on potassium lactate at pH. 7, it assumes a much more expanded form than it does on potassium chloride and other neutral salts, at the same normality and pH. It is interesting to note that it is a hydroxyacid which causes this expansion, as neither acetates nor propionates are effective ; the extension is noted, although to a less degree, with tartrates.
