i've tried by staining with picric acid. its supposed to be in powder form. But the one I have is in solution. What I did was I dip cotton bud into the picric acid, and stain the mice according to my number coding (right front hand = 1, left front hand = 2, right flank = 3, left flank = 4, head =5). I tried this last 2 weeks, and the dye still there and all the mice are ok (no sign of abnormality). just make sure they don't lick the dye before the dye dried. you can apply it by holding the mice by tail.
hope it helps! =)
Isn't this painful for the rodents as you "etch" the skin?
and powdery picric acid (i.e. dry) is an explosive, so you should be extremely carefully...
the one I use is solution based. and may I know what do you mean by 'etch' the skin? I simply stain the hair with solution. the same concept when u dye your hair. i used it on ICR mice. the solution did not cause the hair to fall off or give any scar. but i don't guarantee
the same thing if it is on nude mice.
sorry If i cause misunderstanding
