Clarifier™ 1 is a reagent designed to eliminate background staining sometimes caused by excessive adhesives in the water bath such as gelatin. Clarifier™ 1 selectively removes hematoxylin staining from excess adhesive without affecting nuclear staining. This product is only effective with progressive staining and should not be used with regressive stains. Clarifier™ 1 is designed for use after staining with progressive hematoxylins. After tissues have been sufficiently stained with a progressive hematoxylin, slides are removed from the stain and excess hematoxylin is removed by rinsing the sections in water. The sections are then placed into Clarifier™ 1 for 30 seconds to 1 minute. A 1-minute water rinse should follow as this stops the reaction and rinses excess acid from the tissue section. If Clarifier™ 1 is not successful in removing the background staining, use Clarifier™ 2 in its place with a possible time reduction.
