%X Interleukin-21 is a type I cytokine mainly produced by activated CD4+ T cells that acts as a regulator of immune system.In this work,hIL-21cDNA was amplified from human peripheral blood lymphocytes by RT-PCR,and then inserted into pPIC9K.The recombinant vector pPIC9K-hIL21cDNA was linearized by Sac I,and transformed into Pichia pastoris strain GS115 by electroporation.Transformants were selected by G418 and confirmed by PCR.The recombinant protein was expressed and secreted into the supernatant after induci...
