Tissue processed at a constant temperature of 45 C including the use of paraffin wax with a melting point of 45 C displays staining characteristics that are sometimes reversed from those associated with the more usual processing schedules and wax with a melting point of 58-60 C. Staining with acid dyes, particularly in trichrome methods, are most(More)
Mild gasification of coal is a technology being developed in the United States in order to upgrade lower rank coals and facilitate their use in coal-burning electric generation plants. Thirteen coal-derived mild gasification products from different coal sources and processing conditions have been examined for their potential biohazards. The mutagenicity of(More)
The site-specific immobilization of histidine-tagged proteins to patterns formed by far-field and near-field exposure of films of aminosilanes with protein-resistant photolabile protecting groups is demonstrated. After deprotection of the aminosilane, either through a mask or using a scanning near-field optical microscope, the amine terminal groups are(More)
