You did not say how the articular cartilage is prepared? Frozen sections,
paraffin, decalcified, plastic sections.  Toluidine Blue or saffranin
O/Fast Green work well with paraffin. Toluidine blue is excellent with
plastic sections. IF you have decalcified with EDTA, proteoglycans are
extracted (NOT destroyed) by EDTA and tinctorial quality of these stains
changes.  You will need to control staining using an undecalcified piece of
articular cartilage so you know what might be missing.
