Partially deglycosylated chondroitin sulfate proteoglycan (CSPG) or peptide fragments obtained from CSPG are not readily detectable in gels by staining with Alcian blue 8GX or ammoniacal silver using the technique of Oakley et al. (B. Oakley, D. Kirsh, and N. Morris (1980) Anal. Biochem. 105, 361). Sequencial staining with both reagents allows visualization of intact CSPG or peptides derived from proteoglycans in polyacrylamide gels at protein concentrations as low as 2 ng/mm2, or glucuronic acid and galactosamine concentrations of 1 ng/mm2 or less. This method is significantly more sensitive and has broader applicability than that described by H. Min and M. Cowman (1986) Anal. Biochem. 155, 275) for staining glycosaminoglycan fragments in polyacrylamide gels.
