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)]
Method relies on the examination of the ear’s mechanics, which is actively modulated by the motility of auditory neurons and reflects the function of mechanosensory proteins these cells comprise [5-7]. Mechanical signatures arising from the motility of the neurons are assayed by measuring the vibrations of the antennal sound receiver in the presence and absence of sound. - [Read Mechanical Tracing of Protein Function in the Drosophila Ear Protocol]

In this protocol nuclei isolated from cells expressing the gene of interest are incubated with radiolabeled UTP which is incorporated into nascent RNA transcripts by RNA polymerase molecules that were actively transcribing at the time the cells were harvested. Because very little denovo initiation of RNA synthesis occurs in isolated nuclei, transcription of the target gene can be measured by hybridizing the radiolabeled RNA to an excess of the target gene immobilized on a nitrocellulose or nylon - [Read Protocol for Transcriptional Run- On Assays]
