Abstract
The invention relates to a method for treating a biological sample, comprising the following method steps: i) preparation of a biological sample and ii) bringing the biological sample into contact with a composition, comprising: (1) 1 to 100 wt. % of at least one polyol and (2) 0 to 99 wt. % of at least one additive, wherein the total amount of components (1) and (2) is 100 wt. %. The invention further relates to biological samples obtained by said method, a method for analysis of a treated biological sample, devices for treating a biological sample, use of said devices, various kits and use of a composition.
Claims29
A method of stabilizing a biological sample, comprising:
- i) providing a biological sample, and
- ii) contacting the biological sample with a composition comprising:
- (α1) from 1 to 100% by weight of at least one polyol selected from the group consisting of a diol, triol, tetraol, pentaol, hexaol, heptoal, octoal, and nonaol, and
- (α2) from 0 to 99% by weight of an additive selected from the group consisting of monohydric alcohols (monools), ketones, dimethyl sulfoxide, aromatic hydrocarbons, halogenated hydrocarbons, ethers, carboxylic acids, carboxamides, nitriles, nitroalkanes and esters,
- wherein the total weight % of components (α1) and (α2) in said composition amounts to 100% by weight.
