General description
Furthermore, imidazole is indispensable for enhancing protein purity. It is widely used in preparing buffer solutions optimized for downstream purification columns. Imidazole solutions are also effective elution and washing agents throughout protein purification processes. Additionally, imidazole can be used for assays of horseradish peroxidase (HRP) and reverse staining of SDS-PAGE gels for protein detection. Imidazole is a versatile and valuable reagent for a wide range of biological applications. It is an essential component of many buffers and is also used in protein purification and detection protocols.
Application
- in the lysis, wash and elution buffer for the purification of histidine tagged Sonic Hedgehog(shh-N) protein
- in elution buffer in stepwise gradient for the purification of histidine tagged aldo keto reductases using nickel affinity chromatography
- as a component of homogenization buffer for the purification of phagosomal compartments from dendritic cells
- as a binding buffer, wash buffer, and elution buffer in a study involving protein expression and purification of bioactive growth factors for use in cell culture and cellular agriculture
