Unmasking Fluid P ( 0.1% Pronase)

Catalogue number: DE110

Units5 ml
Application IHC(P)

One of the most popular methods for antigen unmasking following formaldehyde fixation is 0.1% Pronase. It is easy to use and often preferred since it does not require high temperature. Good results have been obtained for instance with Collagen type IV, Cytokeratins, EpCAM (HEA 125), IgG, IgM, Kappa- and Lambda-chains, LCA, MAC 387, Melanoma (HMB45), Neurofilaments, p170 Glycoprotein, S-100, T-cells (CD3), Vim 3B4, Von-Willebrand-Factor. Aldehyde fixation (Formaldehyde fixation) of tissues generally causes cross-linkage of protein chains and results in masking of antigens present in the treated tissue. This makes the antigen epitopes undetectable for many antibodies applied for immunohistochemistry. Mainly monoclonal antibodies, but also mono-specific polyclonal antibodies will react with reduced binding or no binding at all. Since Formaldehyde fixation is the most important fixation method in routine histology, high temperature unmasking methods for immunohistochemistry, as developed during recent years, are very important tools for cell and tissue research and pathology.
