Intended Use For Mohs In Vitro Diagnostic Use
Summary and Explanation

The Mohs ImmunoDigestor is used for the enzymatic digestion of frozen tissues prior to immunohistochemical (IHC) [procedures.

The enzymatic digestion of frozen tissues fixed with acetone or NBF 10%, improves accessibility of antibodies to epitopes within tissue sections.  In the case of IHC, proteolytic digestion exposes certain epitopes which have been masked during fixation, especially with NBF10%.

Presentation The Mohs ImmunoDigestor is provided in liquid form ready-to-use.  It contains optimized Proteinase K, a buffer solution, detergents, and sodium azide anti-microbial.

Recommended Protocol

  1. For Frozen Mohs sections fixed for 2 min. with Acetone or 10% NBF 10%, incubate slides with ImmunoDNA Digestor for 1 minute at 37°C or at room temperature.
  2. Rinse slides briefly in distilled or deionized water (10-20 seconds).
  3. Proceed with Mohs IHC protocol.
