It is possible to use an instrument known as a microdensitometer or microspectrophotometer to actually measure the intensity of the pink Feulgen reaction for a given organelle.

Considering the influential scientific legacy that the Feulgen reaction brought with it, here we discuss the impact of this cytohistochemical method, highlighting the ongoing significance and …

This inexpensive, nontoxic, and easily performed stain enhances nuclear chromatin pattern (surrogate Feulgen stain), removes unwanted background debris, and optimizes cellular …

Mar 15, 2020 · The pink color intensity correlates with DNA content in cell. However, Feulgen technique is a semi-quantitative.

It is, probably, the most simple cytochemical method allowing indication and evaluation of DNA levels into cells. Schiff's reagent is the stain used in this technique.

The German chemist Robert Feulgen developed a histochemical staining technique in 1924 that detects DNA in cells and tissues. It was groundbreaking because it provided one of the first …

Rather than extracting the DNA from cells, this method involves staining the nuclei and then measuring the amount of light absorbed by the stain. The most commonly employed method …

Among different staining methods to demonstrate the nuclear abnormalities, Feulgen is one of the most reliable method. The Feulgen staining is a specific and sensitive method for evaluating …

The intensity of staining by the Feulgen reaction is proportional to the concentration of DNA. Thus it is possible to make microphotometric and morphometric observations and determine the …

Download scientific diagram | Feulgen staining of nuclei in onion tip cells. The tissue consists of more than one layer of cells. This resulted in numerous dark pink nuclei on the field of...
