[Histonet] BUGZ

From:Lori Charette



Hi Amos,
You can decalcify with hydrochloric acid with a chelating agent like EDTA.
0.5M EDTA pH 8.0 (GIBCO) 30ml
ddH2O 70ml
6N HCL 1.2ml
pH 6.4-6.8
1. Wash fixed tissue with PBS  20min X3.
2. Wash tissue with ddH2O 20min X3.
3. Change tissue to EDTA solution with agitation at RT for 2-3 days 
depend on tissue size.
4. Change to fresh EDTA solution if need further decalcification.
5. Rinse with ddH2O 20min X3.
6. Wash with ddH2O 20min X3.
7. Dehydration and embedding
I did not see much in the insect world but there is some info in the 
invertebrate world.
Lots of exoskeleton and chitin there.
Hope this helps.
Lori

> Hello, this message is mainly for the boneheads and plastics users (specifically Technovit 7200, GMA and others using the Exakt system).  I will be attending the NSH conference for the first time.  I don't know many people involved in plastics, so I was wondering who else would be attending that is familiar w/the plastics I mentioned above.  I'd certainly like to meet a few of you!  Also any friendly words of advice about getting the most out of the conference would be appreciated!
