Values are mean ratios of absorbance at 260 nm to 280 nm ± SD n=8 for all retina measurements, n=10 for whole eyes except the pellet pestle (n=9). ANOVA multiple comparison analysis compared the mean of each technique within a tissue type (retina or whole eye) with the mean of every other technique for the same tissue. A full list of comparisons with p values is given in Appendix 3 and Appendix 4.
