It may however if you're doing immunofluorescence, as MB has been used to quench autofluorescence (Seeing the Wood through the Trees: A Review of Techniques for Distinguishing Green Fluorescent Protein from Endogenous Autofluorescence; Nicholas Billinton and Andrew W. Knight, Analytical Biochemistry 291, 175–197 (2001). It isn't likely to alter antigen-antibody binding if that's what you meant.

Should not be a problem if you are using hrp/dab brown or ap/red detection.

Hello Histies,

I received rodent dermis that has been stained with methylene blue.

I would like to perform immunolabeling experiments on this tissue.

Should I expect any interference from the methylene blue stain?

Tim Quinn
