|Product Overview :
||Recombinant proteins tagged with 6-10 poly Histidines can be purified in one step by ion metal affinity chromatography (IMAC). Several metal ions exhibiting affinity to poly-Histidines are commonly used, Nickel and Cobalt being the most popular. Tagging the proteins may be done at the N-ter or the C-ter by cloning a gene in dedicated expression vectors encoding to the poly Histidines stretch, enabling the purification of the recombinant protein resulted.
