Immunofluorescence Labeling of Cells

Cell staining can be divided into four steps: cell preparation, fixation, application of antibody, and evaluation.

RNAi In Situ

In Situ Hybridization of Whole-Mount Mouse Embryos with RNA Probes: Hybridization, Washes, and Histochemistry. This is a protocol describing how to perform in situ hybridization on whole mouse embryos. Here we describe the hybridization procedure, and the localization of the DIG-labeled RNA using a conjugate of anti-DIG Fab antibody and calf intestinal alkaline phosphatase. Enzyme activity of the reporter is detected by a color reaction, resulting in the formation of a water-insoluble purple/blue precipitate. Manipulating the Mouse Embryo - Third Edition
