| Popis: | Microwave oven antigen retrieval has been developed to extend the range of antibodies that can be used upon sections of fixed and processed tissue. It has the additional advantages of improving immunostain intensity and reducing background positivity. It can also be employed as an alternative to proteolytic digestion. In this study the effects of microwave oven heating upon immunochemical staining of cytopathological specimens with a range of selected antibodies have been investigated. Microwaving did not result in loss of cells, and there was no need to use adhesive-coated slides. The method improved the staining intensity and reduced background with antibodies against a variety of antigens that are difficult or impossible to detect in formaldehyde-fixed cytological material. Microwave heating was also used successfully as an alternative to trypsin digestion, and had the advantage of reduced morphological distortion. The technique was useful in demonstrating the soluble formalin-sensitive antigen p19 on cytospins fixed in formaldehyde vapour. Microwave oven heating thus shows promise of extending the scope of immunostaining in clinical cytopathology. |
