Clonal expression of P. falciparum variant surface antigens. a Transcription of surface expressed gene families: vars (78/78), rifins (155/185), and stevors (35/36) is displayed as the mean (log₂ expression value) and ±s.e.m. throughout the 48 h IDC. The hpi where peak transcription of each gene family is displayed as a dropline in each graph. b At the peak time of transcription, the expression value for each var (sub-groups and pseudogenes are labeled), rifin, and stevor genes
