FIG. 2.

Comparison of fading times for the various fluorochromes used with EM. The numbers in parentheses are the coefficients of variation for the fading times obtained with six samples that originated from the different bodies of water sampled. The table shows the results obtained by a one-way analysis of variance in which Fisher's least-significant-difference test was used. An asterisk indicates significance at a level of P < 0.05. NS, not significant. O-YOPRO, original YOPRO; M-YOPRO, modified YOPRO; SYBR I, SYBR Green I.
