rilevamento di<em> Trypanosoma brucei</em> Switching Variante superficie glicoproteina da magnetico cellulare Attivato Ordinamento e citometria a flusso
African trypanosomes grown in vitro undergo antigenic variation at a low rate, such that populations are made up of parasites expressing a dominant variant surface glycoprotein (VSG) type and a small population of "switched" variants. This protocol describes a fast method for detecting and quantifying these populations.
