I have been undertaking sirius red staining using picric acid, I was under the impression (from papers) that picric acid is an important component of the procedure and read that it prevents non-specific binding of the dye to things other than collagen. However, I have recently found a paper which suggests I can simply use water instead of picric acid, seems quite a long shot but I wondered if anyone has experience with the water technique- given that picric acid is pretty dangerous I would be keen to move away from using it but only if scientifically sound to do so. I don't want to jeopardize my results but if this method works then it's a far safer and cheaper safer approach. Any advice?
