Abstract:
This protocol describes the quantification of DNA using PicoGreen and a fluorometer to determine the concentration of DNA sample for downstream processing. Because dye-based methods will not detect degraded or short DNA fragments, PicoGreen requires DNAs ≥50 bp, but can less reliably detect fragments as small as 20 bp.

Reporter Genes
13.7K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

Fluorescence and Phosphorescence: Instrumentation
1.8K
Fluorometers and spectrofluorometers are two types of instruments used for measuring molecular fluorescence. These instruments differ in how they select excitation and emission wavelengths and the type of light sources they utilize. Fluorometers use absorption interference filters to choose excitation and emission wavelengths. The excitation source in a fluorometer is typically a low-pressure mercury vapor lamp that emits intense lines distributed throughout the ultraviolet and visible regions.
