<html><div>is there a reason not to make a solution of napthol AS-D
chloroacetate in formamide for use in the Leders stain and store
the aliquots of the solution rather than weighing out the relatively
small gram amounts each time. considerations would be shelf life of
the substrate in solution. </div>
