Question:
Do the samples degrade during transit to the laboratory?

The ethanol in the 50 ml tubes helps to preserve the DNA. Refrigeration also slows the degradation process. DNA degradation will be faster at ambient temperature but should not have a large effect on sample outcome. It may be advisable to refrigerate the sample for a few days in excessively hot weather.
