The structure and function of human erythropoietin is under increasing
ly intense study, owing both to the therapeutic importance of the horm
one and to its biologic relevance. A combination of approaches using b
iomechanical, immunochemical and molecular biologic techniques has pro
vided new insights into erythropoietin's critical structural features.
Both the protein's amino acid components and its attached complex car
bohydrates contribute to its physiologic and pharmacologic properties.
