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.

Description

Technical field

[0001] The invention relates to a method for making souvenirs or handicrafts carrying individual biological cells and their DNA, which can be used for households or individuals to permanently store biologically active DNA molecules, belonging to the field of biotechnology. Background technique

[0002] Deoxyribonucleic acid contains the genetic information of almost all biological individuals and is one of the greatest discoveries of the 20th century. In the middle of the last century, James Watson and Francis Crick revealed the double helix structure of DNA molecules, put forward the famous central law, laid the foundation of the entire molecular genetics, and created a new era of human understanding of life. Because of this fundamental contribution, the biological sciences have made rapid progress in the past half a century. People can amplify a small amount of DNA of a biological individual millions of times in a short time, and can quickly and low-cost biologi...
