Quantitative glass paper chromatography: a microdetermination of plasma cholesterol*
Journal of Lipid Research, 1960 A rapid, sensitive method for the determination of sterols is described. Microgram samples are spotted on impregnated glass fiber paper, chromatographed for 7 minutes, dried, sprayed with sulfuric acid, and charred by heating.

Detection of steroids in paper chromatography [PDF]
Archives of Biochemistry and Biophysics, 1952 Summary o 1. Methods for the detection of steroids in paper chromatography have been described and evaluated for 31 compounds. 2. A new method of detection of steroids involving phosphomolybdic acid has been reported. 3. A method using silicotungstic acid has been extended to cover many new compounds.

Chromatography of lipids on commercial silica gel loaded filter paper
Journal of Lipid Research, 1965 Commercial silica gel loaded filter paper has been found to give good separations of neutral lipids and phospholipids. Unidimensional or two-dimensional chromatography can be used. Rat liver lipids and C14-algae lipids were studied.

SOME PROPERTIES OF VARIOUS FRACTIONS OF THE SEEDS OF ARISTOLOCHIA BRACTEATA [PDF]
Assiut Veterinary Medical Journal, 2006 Paper chromatography of different fractions of the seeds of A. bracteata was carried out. The Rf values were recorded and the spots were exposed to U.V. light. The alcohol extract gave five spots. Four yellow spots were seen in U.V.

Paper Chromatography as Exemplified by Separation of Urocanic Acid and Deaminohistidine
Bio-Protocol, 2013 Paper chromatography is an ancient technique to separate low molecular mass compounds based on their distribution between mobile phase (solvent) and stationary phase (cellulose and cellulose-bound water). Paper chromatography has been largely replaced by

Two-dimensional chromatography on silica gel-loaded paper for the microanalysis of polar lipids
Journal of Lipid Research, 1966 Two-dimensional chromatography on commercially available silica gel-loaded paper for the microanalysis of polar lipids from various tissues is described. All common phospholipids and their lyso derivatives can be reproducibly separated.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface
FEBS Open Bio, EarlyView.HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral
