Construction of a new polycistronic vector for over-expression and rapid purification of human hemoglobin.

abstract：:Nonviral gene delivery has gained a lot of interest as a promising approach for gene therapy. Despite intensive studies and much progress the outcome of nonviral vectors has remained significantly weaker than that of viral vectors. A weak transfection efficiency of nonviral gene transfection is still limiting their in...
