Phenotypic and <i>va</i>r transcriptional profile of parasite panel.

aThe ability of infected erythrocytes to float in 0.7% gelatin was used as a surrogate for knob positivity. bIndicates whether the knob-associated histidine rich protein gene could be amplified from cDNA. cProfiling of var transcription was performed after initial parasite expansion following limited dilution cloning. Transcripts representing greater than 5% of the total var messages are listed. dProfiling of var transcription was repeated at the time of infected erythrocyte binding assays as above. nd - not done.
