Many of our users have found that when using water for injections instead of Hi-Di formamide, they end up with issues that prevent base calling, even when following the machine standards. Proper technique should produce signal strengths well above the minimum threshold when samples are resuspended in formamide.
However, if you are still having issues with signal strength, you can try resuspending your samples in water, since this can increase signal strength by over 10x. If you do try employing water for injections, make sure you’re cautious of these three things:
