Notizen:
Conditions affecting the solubilization of variant surface glycoprotein (VSG) from Trypanosoma brucei have been investigated. The results obtained form the basis for a convenient and efficient method for VSG purification. VSG release from the cell surface was temperature-dependent, following osmotic lysis at 0 °C, and was inhibited by low concentrations of Zn2+ but not by tosyl-lysine chloromethyl-ketone (TLCK), phenylmethylsulfonylfluoride (PMSF), or iodoacetamide. These and other results eliminated the possibility that release was due to proteolytic cleavage of the C-terminal hydrophobic tail present on newly synthesized VSG. Bolton and Hunter reagent reacted with several components on living cells.
