| 摘要 |
The present invention concerns the methods and compositions for preparing a tissue section or biological sample, particularly to preserve RNA in the section or sample, by not exposing or contacting the sample or section to a solution that is composed of mostly water. Tissue sections can be fixed, stained, and dehydrated for subsequent manipulation, including laser capture microdissection (LCM) for further analysis using methods and/or compositions of the invention.
