生物活性

Imidazole is a planar 5-membered ring. Imidazole is a highly polar compound. Imidazole has been used extensively as a corrosion inhibitor. Imidazole is incorporated into many important biological molecules. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Imidazole is useful as a buffer in the pH range of 6.2-7.8 One of the applications of imidazole is in the purification of His-tagged proteins in immobilised metal affinity chromatography(IMAC). Imidazole is used to elute tagged proteins bound to Ni ions attached to the surface of beads in the chromatography column. An excess of imidazole is passed through the column, which displaces the His-tag from nickel co-ordination, freeing the His-tagged proteins. Imidazole has become an important part of many pharmaceuticals. Synthetic imidazoles are present in many fungicides and antifungal, antiprotozoal, and antihypertensive medications. Imidazole is part of the theophylline molecule, found in tea leaves and coffee beans, which stimulates the central nervous system. It is present in the anticancer medication mercaptopurine, which combats leukemia by interfering with DNA activities.

Details

SiliaMetS Imidazole weight: 8 g

Size: 5 cm wide x 1 cm long

Metals removed

  • Best scavenger: Cd, Co, Cu, Fe, Ir, Li, Mg, Ni, Os, W & Zn
  • Good scavenger: Cr, Pd & Rh

To facilitate the evaluations of small samples, we can provide loose media and lab scale cartridges on a custom basis.
Testing with loose media can be done with samples as small as a few milliliters and are normally done in advance of cartridge testing to identify the formula with the highest capacity to remove contaminants with the least loss of product.

E-PAK lab cartridges are generally used for processing samples of 50 ml or more. Testing has shown good correlation between the performance of lab, pilot and commercial size cartridges.

Lab cartridges can be operated with pump (as shown) or small pressure vessel.
