Embodiment Construction

[0015] The present invention will be specifically introduced below in conjunction with specific embodiments.

[0016] 1. Preparation of relevant reagents

[0017] The composition and dosage of each group in table 1

[0018]

[0019]

[0020] In the preservation solution of the present invention:

[0021] (1) using hydroxyethyl starch as an osmotic pressure regulator;

[0022] (2) Use potassium dihydrogen phosphate / dipotassium hydrogen phosphate as a pH buffer pair, which belongs to non-CO 2 Dependent buffer pair, which can reduce the exposure of isolated tissues to CO during transportation and exposure to air 2 Dependence, reducing pH fluctuations;

[0023] (3) Create a hyperosmotic and high potassium environment, which can reduce the swelling of cells and tissues, and enhance the vitality of isolated tissues;

[0024] (4) The antibiotic used is gentamicin sulfate, which can interfere with the function of the riboprotein body by firmly binding to the specific protei...

Abstract

The invention discloses a novel in-vitro tissue preserving reagent. The novel in-vitro tissue preserving reagent comprises 15-500 g of osmotic pressure conditioning agent, 1-100 g of pH value buffer pair, 1-150 g of potassium chloride, 1-50 g of sodium chloride, 1-300 mg of antibiotics, 100-500 g of recombinant serum albumin and 1000 ml of DMEM complement. The novel in-vitro tissue preserving reagent has the advantages of not containing animal components, being safe and reliable to use, having completely definite components, making quality easily controlled, achieving a ready-to-use effect, and being more convenient to operate, capable of being stored at room temperature and quite convenient to store.

Description

technical field [0001] The invention relates to a preservation solution, in particular to a novel isolated tissue preservation solution, and belongs to the field of biotechnology. Background technique [0002] The existing organ preservation solutions are mainly imported, which are not only expensive, but also have high requirements on the transportation environment and are extremely inconvenient to store. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a novel isolated tissue preservation solution, which not only reduces the cost, but also has low requirements on the transportation environment, and can be stored at room temperature, and the storage is extremely convenient. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A novel isolated tissue preservation solution is characterized in that the components and do...
