23 Jul Method for long-term household preservation of individual biological tissue cells and active DNA of individual biological tissue cells
Abstract
The invention discloses a preparation method of a souvenir carried with individual biological tissue cells and DNA, and belongs to the field of biotechnology. The organism materials separated from an organism are easy to decay and difficult to store; although a mature method in the biomedical field is provided, a storage mode of the method is unsuitable for household and personal applications. The invention aims to provide a storage method and a preparation process of individual biological cells and a complete genome thereof for household collection. The method disclosed by the invention comprises the following steps of sample collection, fixation, dyeing, dehydration, hyalinizing/sealing, molding and the like. The method has the beneficial effects that the individual biological DNA is completely preserved in a cell nucleus in situ according to a genome unit, i.e., non-renewable human genetic information resources are persistently preserved, so that the biological engineering operation taking a single cell, a single cell nucleus and a single genome as units can be easily carried out in future, and thus an immeasurable value and contribution for future people to research genetics and human evolution is provided.
