Using Direct Red 80 with Picric acid P6744 for Picro Sirius Red staining, and the staining resultss are coming out very yellow. Any advice on this issue?
1 answer-
Direct Red 80 is not performance tested for use in a Picro Sirius Red staining method. Tissues fixed or stained with Picric Acid may require long rinse or wash steps to remove excess picric acid, and using slightly acidified water has been seen in protocols to remove the excess picric acid from tissue sections.
