Immuno-affinity solid-phase extraction

Journal of Chromatography B: Biomedical Sciences and Applications, 2000
The measurement of trace organics such as drugs and pesticides at low concentration in biological and environmental samples is a challenging analytical task. Despite recent advances in instrumentation most analysts regard sample preparation as the rate-limiting step in the overall analytical method.

Solid-Phase Extraction in Malondialdehyde Analysis

Analytical Biochemistry, 1997
Malondialdehyde (MDA) has been widely used as an index of lipoperoxidation in biological and medical sciences as well as in the food industry. A solid-phase extraction (SPE) of the condensation product of the MDA with 2-thiobarbituric acid (TBA) was developed using LiChrolut C18ec, 200 mg (Merck, Darmstadt, Germany), as a SPE cartridge and methanol as ...

A magnetizable solid phase for enzyme extraction

Applied Biochemistry and Biotechnology, 1991
A method for the convenient and reliable preparation of magnetizable agarose beads containing iron particles is described. The beads were treated with the triazine dye, Reactive Red 120, and the matrix was examined for the ability to extract proteins from crude preparations using lactate dehydrogenase from porcine muscle as a model.

Graphitized carbons for solid-phase extraction

Journal of Chromatography A, 2000
The objective of this review is to provide updated information about the most important features of graphitized carbonaceous sorbents used for solid-phase extraction (SPE) of organic compounds from liquid natural matrices or extracts. The surface characteristics of graphitized carbon blacks and porous graphitic carbons are described which are ...

Ion-pair solid-phase extraction

Journal of Chromatography A, 2000
Solid-phase extraction (SPE) is a technique widely employed by analytical chemists. SPE cartridges are available in a wide variety of formats containing media with diverse chemistries. This paper will review ion-pair SPE, one of the less frequently applied, and presumably less well-known techniques.

Solid-phase extraction for combinatorial libraries

Journal of Chromatography A, 2000
Solid-phase extraction (SPE) has during the last three years emerged as a convenient method for the purification of compound libraries prepared by solution synthesis. The widespread use of SPE in combinatorial chemistry can be explained by straightforward SPE method development facilitated by the availability of numerous commercial SPE resins.

DNA Extraction: Organic and Solid-Phase

2016
DNA extraction remains a critical step in DNA profiling of biological material recovered from scenes of crime. In the forensic community several methods have gained popularity, including Chelex(®), organic extraction, and solid-phase extraction. While some laboratories streamlined their processes and only use one method we have retained several methods
