Western Blotting: detects a 23-25kDa protein and DM20 a 20kDa protein; PLP can aggregate causing HMW bands to sometimes appear in certain preparations.
Immunocytochemistry: 4% PFA fixed cells, 5-10 minutes room temperature. Use 0.1% triton in block only to allow antibody access to C-terminal epitope.
Immunohistology on fresh frozen sections or 4% PFA fixed, frozen tissues. Epitope is internal, use 0.1-0.2% triton X-100 in the blocking step for permeabilization.
Immunohistochemistry in paraffin: works best with lightly fixed tissues, or Bouin's fixed material, although there are reports of traditional formalin fixation also working with antigen recovery. {Mathis, et al 2003}.
Optimal working dilutions must be determined by end user.
