Extraction of haemoglobin from human blood by affinity precipitation using a haptoglobin-based stimuli-responsive affinity macroligand

Gisela Stocker Majd

Affinity precipitation was compared to affinity chromatography and batch adsorption as the final purification step in a protocol for the isolation of haemoglobin from human blood. Haptoglobin was the affinity ligand. The first steps on the process were rea ...

The possible role of hydroxylation in the detoxification of atrazine in mature vetiver (Chrysopogon zizanioides nash) grown in hydroponics

Jean-Paul Schwitzguebel, Sylvie Vullioud-Marcacci

The resistance mechanism of vetiver (Chrysopogon zizanioides) to atrazine was investigated to evaluate its potential for phytoremediation of environment contaminated with the herbicide. Plants known to metabolise atrazinerely on hydroxylation mediated by b ...

Numerical Simulation of Two-Phase Partition Chromatography in Microchannels for Moderated Log P Measurements

Hubert Girault, Pierre-Alain Carrupt

A finite element simulation has been used in order to study the partition chromatography process of one species between an aqueous mobile phase and an organic stationary phase located at the bottom of a rectangular microchannel. The transient model incorpo ...

Identification and overexpression in Escherichia coli of a Mycobacterium leprae gene, pon1, encoding a high-molecular-mass class A penicillin-binding protein, PBP1.

Stewart Cole

Cosmid B577, a member of the collection of ordered clones corresponding to the genome of Mycobacterium leprae, contains a gene, provisionally called pon1, that encodes an 821-amino-acid-residue high-molecular-mass class A penicillin-binding protein, provis ...

Purification of telomerase from Euplotes aediculatus: requirement of a primer 3' overhang

Joachim Lingner

Telomerase is a ribonucleoprotein enzyme that uses its internal RNA moiety as a template for synthesis of telomeric repeats at chromosome ends. Here we report the purification of telomerase from Euplotes aediculatus by affinity chromatography with antisens ...
