NHS活化琼脂糖层析填料

产品简介：

NHS (N-hydroxysuccinimide)-activated agarose has a well-proven track record for the preparation and use of custom affinity chromatography media. Coupling biospecific ligands to NHS-activated agarose is a successful and well-documented technique. The coupling reaction is spontaneous, rapid and easy to carry out. No toxic chemicals or special equipment is required.

NHS-activated SepFast media forms chemically stable amide bonds with ligands containing primary amine groups. The activated NHS group has a long spacer arm (11 atoms) that is particularly helpful in the immobilization of structurally restricted ligands such as proteins and peptides. This pre-activated agarose base matrix can be readily employed to make various custom affinity chromatography adsorbents for both small scale and large scale purification applications.

产品属性：

NHS activated SepFast 4HF is made of highly cross-linked 4% beaded agarose. It shows high mechanical rigidity allowing high flow throughput with reduced back pressure in a packed column.

Agarose has long been used for chromatographic separations due to its excellent hydrophilic and low non-specific-binding nature. The particles have an open pore structure with excellent mass transfer properties to various molecules.

The base matrix is activated through a long hydrophilic spacer arm (11 atoms) with N-hydroxysuccinimide at the end. It reacts directly with the primary amine groups in molecules to be immobilized to form stable amide bonds. NHS-activated SepFast media is supplied as a suspension in 100% isopropanol.
