Product description: Free DNA preservation solution is a liquid specifically used to preserve free DNA, which is an important genetic material in organisms and plays a crucial role in studying and analyzing biological processes. In order to maintain the integrity and stability of DNA samples, many laboratories have developed free DNA preservation solutions that can preserve DNA samples for a long time at room temperature without losing their integrity and usability. Advantages and usage considerations 1. Free DNA preservation solution can store DNA samples at room temperature for several months or even longer without degradation or loss of their integrity. It is easy to use and only requires adding DNA samples to the preservation solution and gently mixing them. It is suitable for various DNA samples, such as blood, tissue, cells, etc. 2. Free DNA preservation solution is usually stable at room temperature, but should be stored in a dark and cool place, avoiding high temperatures and direct sunlight. It is not suitable for frozen storage, as freezing can cause precipitation and denaturation of the components of the preservation solution. In addition, once a DNA sample is added to the free DNA preservation solution, even if it is not fully used, it cannot be reused to prevent cross contamination.
