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...

Study of phenylketonuria by paper chromatography

Detection by paper chromatography of imidazoles, including hydantoin-5-propionic acid, in urine after histidine dosage.

Simple paper chromatography of urine obtained in the Figlu test has been found satisfactory for determining excess excretion of the imidazole metabolites of histidine. It has been confirmed that examination for these in addition to formiminoglutamic acid is necessary for a full assessment of this test. When excretion of the latter is not abnormal in folic-acid and/or vitamin B(12) deficiency, t...

Paper Chromatography

In this laboratory exercise we will separate and identify the cations in an aqueous mixture that possibly contains Fe 3+ , Ni 2+ or Cu 2+ salts. The separation will be achieved using Paper Chromatography. Identification of the cations will be affected by simultaneously running separate solutions, each containing a single salt of these ions, through the chromatographic system and comparing the r...

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...
