产品简介

Affinity Chromatography
Affinity chromatography is a well-known method for separating and purifying biological materials, based on their biochemical affinity. The Shodex AFpak series columns use rigid

产品详细信息

The columns have the following features:

1) Rigid polymeric media enable high-performance analysis.

2) Chemically stable bonding groups (spacers) between ligands and substrates minimize detachment of ligands, ensuring highly reproducible analysis. Up to hundreds of runs are reproducible.

Chiral Separation (ORpak CD)

Besides the positive and negative properties of optical rotation, optical isomers have the same physical and chemical characteristics. Optical separation columns are indispensable for direct analysis without derivatization. Shodex ORpak series incorporate packing material bonded by ligands that can identify many optical isomers.

ORpak series has the following ligands: cyclodextrin derivative (CD).

Because CD is used as the ligand, these columns are suitable for the analysis of optical isomers that make up an inclusion complex with CD. alpha-CD is used as the ligand in CDA, beta-CD is used as the ligand in CDB and CDBS and gamma-CD is used as the ligand in CDC. As a result, different columns can be used based on the size of the hydrophobic area of the optical isomer that is included. Packing materials in CDB and CDBS columns are different. Since CDBS is packed with silica gel, the peaks are sharp and many optical isomers can be analysed. Since CDB is packed with polymer-based gel, a wide range of separation conditions is possible, including alkaline separation. Since beta-CD identifies the most optical isomers within the CD's, CDB and CDBS are suitable for preliminary studies of optical isomer analysis. The CD series are suitable for the analysis of, not only optical isomers, but also structural isomers that have similar structure.

Chiral Separation (ORpak CRX-853)

These are columns for separating optical isomers by ligand exchange using L-amino acid derivatives as the ligand. Eluent containing copper ions are used such as copper sulfate solutions. These columns can be used to analyze optical isomers of compounds which comprise a complex with copper, such as amino acids and acid hydroxyl groups, as well as their derivatives.
