Description
A DNA sequence encoding the mouse IL15 (P48346-1)(Met1-Ser162) was expressed with a polyhistidine tag at the C-terminus, constructed the plasmid 1; A DNA sequence encoding the mouse IL15RA (Q60819-1) (Met1-Lys205) was expressed with a polyhistidine tag at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the IL15 & IL15RA heterodimer was purified
