Figure 2From: Evaluating RNAlater® as a preservative for using near-infrared spectroscopy to predict Anopheles gambiae age and speciesAge residuals for fresh and RNA later® preserved samples of three strains of An. arabiensis and one strain of An. gambiae s.s . as determined by Mann-Whitney rank test. No significant differences were observed between medians of residual age for fresh and RNAlater® preserved specimens for all four strains.Back to article page
