A pteridine adsorbent for affinity chromatography

Preparation of Plasminogen by Affinity Chromatography

Background: Plasminogen is one of the compounds derived from human plasma. Activation of plasminogen produces plasmin. Plasmin is able to lyse fibrinogen, fibrin, and some other human plasma proteins. The aim of the present work was to study the separation of human plasminogen by affinity chromatography using gel lysine Sepharose. Materials and Methods: Normal human plasma was used as the...

Affinity Chromatography : A Review

Affinity chromatography is a type of liquid chromatography that makes use of biological-like interactions for the separation and specific analysis of sample components. This review describes the basic principles of affinity chromatography and examines its use in the testing of clinical samples, with an emphasis on HPLC-based methods. Some traditional applications of this approach include the us...

A Generalized Design for Affinity Chromatography Columns

Chelating peptide-immobilized metal ion affinity chromatography. A new concept in affinity chromatography for recombinant proteins.

We report our experimental results supporting the hypothesis that a specific metal-chelating peptide (CP) on the NH2 terminus of a protein can be used to purify that protein using immobilized metal ion affinity chromatography (IMAC). The potential utility of this approach resides with recombinant proteins since the nucleotide sequence that codes for the protein can be extended to include codons...

Preparation and Characterisation of Immunoadsorbents for High Performance Liquid Affinity Chromatography (HPLAC)

The efficacy of activation methods and coupling were studied in the context of performance in batch and fixed bed binding experiments utilizing cell culture fluids or blood plasma as feedstock. Conclusions were drawn regarding selection of solid phase according to pore size, rigidity, pH stability, Chemistry of derivation and activation, and gross concentration of immobilized ligand require...
