Transformation efficiency of N. gonorrhoeae pilT_L201C

Strain	Transformation frequencya
	− DNA	+ DNA
Wild type	<4.97 × 10−6b	2.65 × 10−4 ± 1.35 × 10−4
ΔpilT	<9.40 × 10−6b	<6.44 × 10−6b
pilTL201C	<4.97 × 10−6b	1.69 × 10−4 ± 0.65 × 10−4

^aTransformation frequency = Rif^r CFU/total CFU/µg Rif^r genomic DNA. Values are the average results from 4 independent experiments ± standard errors of the means. Student’s two-tailed t test.

^bLimit of detection.
