[Histonet] Optimizing HE Stains for undecalcified bone

2012-03-08 Thread M.O.
Hello Histonetters!  I am new to staining and can't seem to get good HE
stains from deplacticized undecalcified bone with an implant.  It seems as
though the hematoxylin is staining too dark. Any feedback would be much
appreciated!

The protocol I am using is for after the deplasticization step and says:

100% EtOH for 3 mins, 70% EtOH for 3 mins

Hematoxylin for 6mins, Rinse, .25% Acid Ethanol dip 8-10 times, Rinse

95% EtOH 1min

Eosin for 2mins

Quick Dip 95%, 95%, 100% 100% EtOH

Soak in ProPar for 15+mins


Sincerely,
Merissa

Merissa,

You should very easily be able to get a nice looking HE from deplasticized 
undemineralized bone sections. In fact, try the protocol that I routinely use 
for my MMA embedded specimens:

Deplastification x 3 changes each for 15-30 minutes @ 55-60C w/ gentle dip and 
dunk at half way mark for each change

100% EtOH @ RT for 5 min

95% EtOH @ RT for 5 min

70% EtOH @ RT for 5 min

dH2O @ RT for 5 min

Hematoxylin 2 (from Richard Allen @ Fisher Sci) @ RT for 3 min

Running Tap Water Rinse for 1 min

Clarifier 2 (from Richard Allen @ Fisher Sci) @ RT for 20-30 seconds with a 
gentle dip and dunk at half way mark

Running Tap Water Rinse for 1 min

Bluing Solution (from Richard Allen @ Fisher Sci) @ RT for 20-30 seconds with a 
gentle dip and dunk at half way mark

Running Tap Water Rinse for 1 min

Eosin Y (from Richard Allen @ Fisher Sci) @ RT for 40 seconds

70% EtOH @ RT with 10 gentle dip and dunks

95% EtOH @ RT with 10 gentle dip and dunks

100% EtOH @ RT with 10 gentle dip and dunks

100% EtOH @ RT for 30 seconds

Xylenes @ RT for 3 min

Xylenes @ RT for 3 min

Your problem could be the type of hematoxylin you are using (progressive vs. 
regressive) and the length of time in solution. I would also recommend you try 
a Von Kossa with a MacNeal's tetrachrome counterstain, Goldner's trichrome, and 
maybe a toluidine blue stain with these type of sections.

Best Regards,

Jack
