5. a nitrocellular compound used for embedding (i. Parloidion) storage blocks held in 80% alcohol. hardened with chloroform. mixed with ether and absolute alcohol to prepare.
6. Fixative type useful for preserving organelles
9. celloidin must be
10. which is not a clearing agent chloroform/ethanol/dioxane/xylene
13. Compound fixative containing picric acid
14. Is impacted by fluid type, tissue size and tissue density
16. destruction or digestion of tissues and cells by the enzymes normally presents in cells
17. PEL=100 / used as clearing agent in most labs
18. Fixing agent provides good morphological preservation
21. most common epoxy transitional fluid
22. polymerized formaldehyde is known as
23. 10% formalin is the same as

1. process by which constituents of cells and tissues are fixed in a chemical so that they will withstand treatment with various reagent with minimum loss or decomposition
2. Action of acetic acid on tissue
3. Evidence that fixation was delayed
5. Fixative type that denatures protein
7. Most tolerant decalcifying solution
8. this is an excellent nuclear fixative
11. This is most frequently used for the fixation of speciman's for electron microscopy as it preserves ultra-struture better than any of the aldehydes. It tends to overharden tissue, so fixation should not be prolonged for more than 2 hours.
