The Expression of Recombinant Human Serum Albumin in the Mammary Gland of Transgenic Mice
Human serum albumin (HSA) is widely used in the clinic for the treatment of several diseases in large amount each year. With the increasing demands of HSA in clinic and limited blood resource, recombinant HSA (rHSA) is becoming an attractive and alternative source for HSA production. In this study,...
