Protein Bands Detection by Nanoparticles after Paper Chromatography

Paper chromatography is an analytical technique for separating and identifying mixtures of materials. It is a useful technique since it is relatively quick, and requires small quantities of the material. By emergence of nanotechnology, paper chromatography has found many applications in biology and biotechnology. In this study, we employed gold and silver nanoparticles to detect protein bands a...

Improved diagnosis of classical vs atypical phenylketonuria by liquid chromatography.

Atypical phenylketonuria among infants with hyperphenylalaninemia must be promptly diagnosed and differentiated from classical phenylketonuria, because these patients require different treatment to prevent irreversible neurological damage. Measurement of pteridines in urine by liquid chromatography has been widely used for this purpose. Here we report a rapid, simplified liquid-chromatographic ...

The identification of barbiturates by paper chromatography.

B ECAUSE barbiturates are relatively easily available and much used drugs, specimens from suspected cases of poisoning are frequently submitted to the laboratory for routine chemical examination. Since their urinary excretion begins early (because they are quickly absorbed), they can often be identified 1-2 hours after administration. The specimen of choice for examination is therefore the urin...

Separation of Amino Acids by Paper Chromatography

Chromatography is a common technique for separating chemical substances. The prefix “chroma,” which suggests “color,” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment, chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate...
