Chromatography of Lipids on Commercial Silica Gel Loaded Filter Paper.

The separation of esters of choline by filter-paper chromatography.

7. It is concluded that tran8-tran8-muconic acid is probably a true metabolite of benzene and is not produced in vivo from the ci8-ci8-acid. It is suggested that the 68-c68-acid need not be an intermediate in the formation of the tran8-tranm-acid in the animal body. The expense of this work was in part defrayed by a grant from the Medical Research Council. We are grateful to Prof. R. Cruickshan...

Study of phenylketonuria by paper chromatography

Collection of blood on filter paper for measurement of glycated hemoglobin by affinity chromatography.

We present data on a filter-paper collection and assay method for measurement of glycated hemoglobin (gHb). Onto filter paper dipped into a solution of glucose oxidase (EC 1.1.3.4) and allowed to dry, approximately 20 microL of capillary blood was spotted. For analysis, we eluted the dried blood spot from the paper by soaking in water for 1 h, then measured the gHb in the eluate by affinity chr...

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...
