Re: methyl green as counterstain
|From:||Robert Schoonhoven <firstname.lastname@example.org>|
The following has worked very well for me over the years.
Methyl Green Counterstaining Procedure
0.1 N Acetic Acid
0.1 N Sodium Acetate
Add 755 ml of 0.1 N acetic acid to 264 ml of sodium acetate and adjust
the pH to 4.2 with NAOH
To the above add 20 gm Methyl Green.
Can be stored at room temp.
If staining turns bluish than the solution has started to deteriorate.
1- Rinse in distilled water briefly
2- Place slides in methyl green for 3-5 minutes (or longer )
3- Do NOT rinse with water. Go directly into 95 % EtoH for about 10
dips, then continue through 1 more 95% and 3 100% EtoH changes leaving
the slides in the last absolute for 3 - 5 minutes.
4- Clear with 2-3 changes of xylene and coverslip
