As a follow up to my original questions - I now understand the ceolloidinise is the procedure using celloidin. I am still having trouble finding a vendor for celloidin. Can I substitute LVN in place of the celloidin? Or maybe there is another method to use in this step. Any feedback will be greatly appreciated!

Hi, We are wanting to do the DMAB-nitrite method for tryptophan (Bancroft is the reference). I have some questions about the method. If anyone has experience, please contact me. Below are my questions: 1. Take sections to alcohol. (What percentage? Not sure if this matters). 2. Celloidinise in 0.5 per cent celloidin. (Where can I find celloidinise - is this still sold commercially?) 3. In step 6 of the procedure there is an acid alcohol rinse (anyone know what the acid alcohol concentration should be?) Thanks in advance if you can help!
