Abstract

We compared the staining performance, dye content, solubility, and visual absorption maximum of two batches of alcian blue pyridine variant and of five batches of alcian blue 8GX (C.I. 74240). Whenever possible, we also compared results to those obtained with the same dye batches produced at an earlier date to provide information concerning dye stability. Both alcian blue pyridine variant batches were of high dye content, stable, of satisfactory solubility, and performed well in both the routine Mowry mucin stain and in the critical electrolyte concentration (CEC) stain. Of the five alcian blue 8GX samples, some were also of appropriate dye content, were sufficiently stable, and gave good staining in the two procedures. Two batches, however, were unstable, and three batches were unsatisfactory in staining performance and solubility in the CEC stain. Consequently alcian blue pyridine variant is a superior substitute for alcian blue 8GX.
