The most convenient and commonly used method to visualize DNA in agarose gels is staining with the fluorescent dye ethidium bromide. Ethidium bromide can be used to detect both singleand double-stranded nucleic acids (both DNA and RNA). However, the affinity of the dye for single-stranded nucleic acid is relatively low and the fluorescent yield is comparatively poor. - [Read Detection of DNA in Agarose Gels Protocol]
Protocol for detection of even-skipped transcripts in drosophila embryos with PCR/DIG-labeled DNA probes. This protocol has been used to detect the transcript distribution of a number of genes by in situ hybridization, including evenskipped and seven-up, in whole mount Drosophila
embryos, and engrailed Antennapedia in whole mount grasshopper embryos. Includes: Probe labeling; Evaluation of labeling reaction; Preparation of embryos, hybridization and detection.

Certain fluorescent dyes such as Blankophor have a high affinity for the b -glycosidically linked polysaccharides such as glucan and chitin, which are main the constituents of the fungal cell wall. Therefore, these fluorescent dyes can be used for screening clinical samples for the presence of fungal elements. This procedure can be performed using the following specimens: Nail, Skin, Bronchial alveolar lavage fluid, Sputum and Biopsies. - [Read Detection of Fungi by Fluorescence Microscopy Using Fluorescent Brighteners]
Protocol for detection of mRNAs on cryosections of the cardiovascular system using DIG-labeled RNA probes. Protocol was optimized from a protocol using 35S-labeled RNA probes. It allows to detect the expression of low abundant mRNAs in the cardiovascular system, e.g. of the proinflammatory cytokine GM-CSF in normal human coronary arteries, and of IL6 and gp130 in human failing hearts. The protocol can be combined with immunohistochemistry. - [Read Detection of mRNAs on Cryosections of the Cardiovascular System Using DIG-Labeled RNA Probes]
Detection of Phosphatidylserine Externalization During Apoptosis. Shailaja Kasibhatla et al. An early event in apoptosis is the externalization of phosphatidylserine (PS), a phospholipid normally restricted to the inner leaflet of the plasma membrane. This apoptotic event can be monitored using Annexin V, a PS-specific binding protein. This protocol uses Annexin V-FITC as a probe, but Annexin V-biotin is also available, and binding can be revealed using streptavidin-FITC or oth - [Read Detection Of Phosphatidylserine Externalization During Apoptosis (Subscription Required)]
Most powerful and convincing method to determine if a specific protein is phosphorylated in a physiologically relevant manner is to assay phosphorylation in situ. The procedure described involves incubating cultured cells (e.g., primary neuronal cultures or transfected cells) or tissue preparations (e.g., hippocampal slices) with [32P]orthophosphate, which is then taken up by the cells or tissues and incorporated into the γ-phosphate position of ATP. - [Read Detection of Protein Phosphorylation in Tissues and Cells Protocol]
The protocol gives general considerations for the design of targeting vectors for transgenic mice. The protocol shares tips in the design of knock-out and knock-in vectors and some of their strategies for producing homologously recombined embryonic stem cells.
