Protocol for combined DNA in situ hybridization and immunocytochemistry for the simultaneous detection of nucleic acid sequences, proteins, and incorporated BrdU in cell preparations. Includes: Cell preparations and BrdU labeling; Detection of antigen by immunocytochemistry (ICC); Visualization of ICC antigen; -Gal-BCIG reaction (for producing a blue precipitate visible under brightfield microscopy); Cell processing for in situ hybridization; In situ hybridization (ISH); etc... - [Read Combined DNA In Situ Hybridization and Immunocytochemistry Protocol]
Protocol describes a method for evaluation of mitochondrial function using the fluorochrome CMXRos. CMXRos is sequestered by actively respiring mitochondria, but washed out when the mitochondrial membrane potential is lost. This analysis can be combined with the TUNEL technique or immunocytochemistry. - [Read Flow Cytometric Analysis of Mitochondrial Transmembrane Potential ({Delta}{Psi}m)]
There are several strategies to visualize the antibody. For transmitted light microscopy, color development substrates for enzymes are often used. The antibody can be directly
labeled with the enzyme. However, such a covalent link between an antibody and an enzyme might result in a loss of both enzyme and antibody activity. For these reasons
several multistep staining procedures have been developed, where intermediate link antibodies are used. In this protocol use the Vectastain ABC-kit. - [Read Immunocytochemistry in Free-Floating Sections Protocol]
