title: Glass slide models for immunocytochemistry and in situ hybridization.
abstract: We have developed a model system based on the immobilization of microdroplets (0.1 microliters volumes) of antigens or of target (sense) oligonucleotides onto aminoalkylsilane-coated glass slides. Oligopeptide antigens need to be vapour-fixed in order to achieve efficient immobilization, while oligonucleotides do not require fixation. Protein antigens, exemplified by rabbit immunoglobulin, may be subjected to liquid fixation. The glass slide models are optically translucent and useful both for in situ hybridization and immunocytochemistry. The slides are compatible with detection systems of both light and fluorescence microscopy and permit measurement of staining intensities by microfluorimetry or computerized microdensitometry. The model systems can be used for comparisons of method sensitivities, for characterizing antibody and probe sensitivities and cross-reactivities, and as internal standards or quality controls for immunocytochemistry and in situ hybridization.
