Hello Histonet, The supplier for our decalcifier, TBD-2 from Shandon, is having issues with getting the product out and we will not be receiving it for at least another month. Our samples are piling up and I don't know what I should do, but maybe I can make the decalcifier in-house. I am wondering if I can make my own based on the reagents they listed and their percentages and if certain reagents are not actually necessary.
The samples we typically decalcify are mouse knees (decal time = 2 days), mouse spines (3 days), human bone slabs about 7mm in thickness (7-12 days). Fixation is in zinc buffered formalin, then decalcification, then 70% EtOH. Our choice to use TBD-2 is due to the gentle decalcification for IHC and we get GREAT results. Composition of Shandon TBD-2 Decalcifier: Component Weight % Water 77-80 Formic acid 21-23 Fluorad >1 Sodium citrate >1 Polyvinyl pyrrolidone >1 If you have any input on what reagents I should use and the percentages for making a decalcifier myself, it would be much appreciated! Thank you for you help, Merissa _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
