Upon received, save at freezer immediately if not used. After initial reconstitution with DI water (50-100uL), aliquot if necessary, and save the product at -80°C for future use.
Polio virus RdRp protein is key player in virus invading into human cells, and virus RNA replication inside human cells[1,2,3]. the protein has a right hand palm structure, similar to covid-19 RdRp, zika virus RdRp and dengue virus RdRp proteins[4,5].
The purified protein is part of full length RdRp protein with a c-terminal his tag.
