一般說明
Immobilized heparin has two main modes of interaction with proteins. It can operate as an affinity ligand with affinity for a wide range of biomolecules, including coagulation factors and other plasma proteins, lipoproteins, protein synthesis factors, enzymes that act on nucleic acids, and steroid receptors. Heparin also functions as a high capacity cation exchanger, due to its anionic sulfate groups. Gradient elution with salt is most commonly used in both cases.
Heparin is coupled to the Sepharose™ High Performance base matrix via the N-hydroxysuccinamide coupling method, to give high capacity, performance, and low leakage levels. HiTrap® Heparin HP is delivered in 0.2 M NaCl with 20% ethanol as bacteriostatic agent. Store HiTrap® Heparin HP columns equilibrated with 25 mL of 20% ethanol or a buffer containing a bacteriostatic agent. Equilibration is easily performed with a syringe and the supplied Luer adapter. Seal the column with the supplied stopper and domed nut. The recommended storage temperature is 4° C to 30° C.
特點和優勢
- Heparin binds to a wide range of biomolecules via both affinity and ion exchange mechanisms.
- Immobilized heparin is used for purification of antithrombin III, coagulation factors, and other plasma proteins.
- Simple operation with a syringe, a pump or a chromatography system such as AKTA design
- Stable over pH 5 to 10 and tolerates all commonly used aqueous buffers.

DNA binding proteins form an extremely diverse class of proteins sharing a single characteristic, their ability to bind to DNA. Functionally the group can be divided into those responsible for the replication and orientation of the DNA such as histones, nucleosomes and replicases and those involved in transcription such as RNA/DNA polymerases, transcriptional activators and repressors and restriction enzymes.
