| 摘要 |
The present invention provides compositions and methods for permanently mounting biological specimens. The mounting compositions of the present invention can be used for mounting stained tissue sections or cell smears for long-term storage. Such mounting compositions provide excellent optical clarity and resolution and, thus, the stained specimens mounted with the compositions of the present invention have greater transparency and visibility for microscopic examination. Preferably, the mounting compositions are aqueous based and, thus, slides do not require pre-mounting treatments such as dehydration in alcohol or clearing in xylene. The slides can be mounted directly from water. Moreover, the mounting compositions of the present invention are compatible with all aqueous and organic-soluble chromogens and dyes (e.g., AEC, Fast Red and Fast Garnet stains). In addition, because of their aqueous, non-toxic and non-hazardous nature, the mounting compositions of the present invention can be used in laboratory settings without a hood or other precautions.
