Many applications require a highly controlled method for production of antibodies. In these instances, in vitro methods are favored over production of antibodies in ascites. Generally, in vitro methods result in much higher levels of antibody purity as well as increased performance in most immunoassays. In vitro methods are routinely used at Rockland under cGMP conditions to produce antibodies for our own antibody needs. Rockland Immunochemicals now offers these technologies as custom services to satisfy the growing demand for this level of antibody performance. A ''High Productivity'' serum-free medium, especially formulated at Rockland, as well as serum containing medium are available for all production methods. Please consult with our highly trained technical staff for additional information regarding these services.
