Alkali Scientific Imidazole [Glyoxaline] [1,3 Diaza 2 ,4 cyclopentadiene], 10 Grams
Imidazole is commonly used in protein purification processes as a buffer compound. This 10g reagent plays an essential role in stabilizing pH during affinity chromatography and other separation techniques. Imidazole’s effectiveness comes from its ability to regulate pH and bind to metal ions, which is particularly useful when purifying histidine-tagged proteins. The compound is frequently employed in laboratories conducting recombinant protein expression studies. By facilitating protein binding and elution in chromatography columns, imidazole enables efficient isolation of target proteins. This reagent is widely used in research focused on structural biology, biochemistry, and biotechnology.
