Staining of the Ca2+-binding proteins, calsequestrin, calmodulin, troponin C, and S-100, with the cationic carbocyanine dye "Stains-all".
The Ca2+-binding proteins, calsequestrin, calmodulin, troponin C, and S-100, have all been shown to stain dark blue or purple with the cationic carbocyanine dye "Stains-all", while most proteinsExpand

Biogenesis of transverse tubules and triads: immunolocalization of the 1,4-dihydropyridine receptor, TS28, and the ryanodine receptor in rabbit skeletal muscle developing in situ
Our previous immunofluorescence studies support the conclusion that the temporal appearance and subcellular distribution of TS28 (a marker of transverse (T) tubules and caveolae in adult skeletalExpand
