Abstract
We show that the electrostatic surface properties of substrates affect the conditions of growth for biological lysozyme crystals. It follows from our results that negatively charged substrates, including the untreated washed glasses, adsorb selectively the ionic lysozyme residues and so they are applicable for growing the biocrystals in flat cells. The largest lysozyme crystals we have obtained have the dimensions about 0.7 mm. The results of studies for the temperature dependences of optical birefringence in single lysozyme crystals inside the 3–40°C region are presented. It is revealed that the lysozyme crystals undergo a first-order structural phase transition at T c = 11°C.
