Protein Transport Across the In Vitro Perfused Human Placenta

PROBLEM: Placental transport of various proteins present in human serum, such as immunoglobulins (IgG, IgA), specific anti‐tetanus IgG (anti‐TT‐IgG), and tetanus toxoid‐antigen (TT‐AG), was investigated. In addition, the transport of IgG modified with biotin (IgG‐BT) and 14C‐bovine serum albumin (14C‐BSA, a permeability marker for macromolecules), was assessed.
