TABLE 4 .

ΔC_T values for inositol transporter genes versus the thymidylate synthase gene^a

Species	Gene product	ΔCT
P. murina	ITR1	−0.30
P. carinii	ITR1	−2.76
P. murina	ITR2	−4.56
P. carinii	ITR2	−1.13

^aReactions were performed in triplicate, and the average threshold cycle (C_T) value of the three replicates was determined. ΔC_T values were calculated by subtracting the average C_T value of the thymidylate synthase gene from the average C_T value of the gene from the inositol phosphate metabolism pathway.
