Carboxyl activated SepFast
|>>Introduction||>>Product Charactistics||>>Ordering Info||>>How to Order|
The base matrix is activated by attaching a long 10 atom hydrophilic chain with a carboxyl group at the end. This reacts with amine containing ligands in the presence of carbodiimide agent to form a chemically stable amide linkage. The coupling chemistry is a successful and well-documented technique.
Carboxyl-activated SepFast 4 High Flow (4HF) is made of highly cross-linked 4% beaded agarose. It shows high mechanical rigidity allowing high flow throughput with reduced back pressure.
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 large protein molecules.
The pre-activated base matrix can be readily employed to make various custom affinity chromatography adsorbents for both small scale and large scale purification applications.
Coupling manual is supplied with each product.
