SR3300 is liquid countertype to Calcofluor for researchers needing this widely referenced stain. Note it is less soluble that SR2200.  SR2200 is recommended if superior solubility is needed.  SR3300 can be combined with Evans Blue to prevent autofluorescence of sections. As Evans Blue is classified as May Cause Cancer, Direct Blue 199 Liquid may be considered as an alternative.
