The chromatography of antibiotics on SP-Sephadex
Journal of Chromatography A, 1973Abstract A rapid procedure is described that permits the quantitative separation and determination of ampicillin, dicloxacillin, methacycline, doxycycline and oxytetracycline by means of column chromatography on SP-Sephadex. The compounds are eluted from a column with sodium acetate solutions of concentration 0.005 and 0.01 M (pH 4.5) and assayed ...

Fractionation of starch dextrins on sephadex
Archives of Biochemistry and Biophysics, 1962Abstract Partial resolution of a number of starch dextrins on Sephadex columns was achieved. The dextrins examined were Naegeli amylodextrin, an α-amylase digest of amylose and soluble starch. Resolution according to molecular size was demonstrated in these systems by iodine-staining power and by paper chromatography. Amylodextrin could be completely

Sephadex® induced granulomatous reaction in rats
Experimental and Toxicologic Pathology, 1995Granuloma formation in the rat lung after single or repeated i.v. injections, intratracheal instillation and intradermal implantation of Sephadex beads was studied over a time period from 3 h to 3 mo. Macrophages were identified with the mAB ED1, vascular smooth muscle cells with an mAB against alpha SMC-actin, endothelial cells with a polyclonal AB ...

CHROMATOGRAPHIC BEHAVIOR OF HISTONES ON SEPHADEX AND CARBOXYMETHYLCELLULOSE
Canadian Journal of Biochemistry, 1964The chromatographic behavior of calf thymus histone on different grades of Sephadex with varying degrees of cross-linkages has been studied. Fractions of histone obtained by preliminary separation on carboxymethylcellulose were characterized by chromatography on Sephadex and by electrophoresis on gels of starch and polyacrylamide. Analytical separation

A sephadex extraction of urinary steroid conjugates
Steroids, 1966Abstract A simple method for the isolation of the C 19 and C 21 steroid conjugates from urine with Sephadex G-50 (coarse) is described. Following contraction of the urine volume by Sephadex, the Sephadex cake was washed with ethanol: methanoi (1:1 v/v) mixture and this was added to the contracted urine sample and evaporated to dryness.

RINm5F cell culture on sephadex derivatives
Journal of Biomedical Materials Research, 1993AbstractInteractions between polystyrene sodium sulfonate and insulin‐secreting RINm5F cells have been previously described. When cultured on these microcarriers, cells exhibited normal growth, altered morphology, and inhibition of the insulin secretion was observed.

Partition Chromatography of Oxytocin on ‘Sephadex’
Nature, 1964GEL-FILTRATION on ‘Sephadex’ as a means of purifying natural products has been widely used since its first introduction by Porath and Flodin1. One of its many applications has been to the purification of natural oxytocin2. Experiments conducted during the past 2 years have shown that the purification of oxytocin can be conveniently and effectively ...
