title: Immunoglobulin purification by caprylic acid.
abstract: At laboratory scale, several methods for the purification of immunoglobulins from plasma or serum are available. However, not all of them are equally applicable when the scale-up to the level of the pharmaceutical industry is intended. In this case, among other factors, it must be taken into account the performance and the cost and quality of the end product. Here we present a method of purification based on the differential precipitation of plasma proteins with caprylic acid in a single step that is simple and cheap and can be easily scaled up. This methodology has been successfully applied to the development and production of pharmaceutical product, such as therapeutic antisera where immunoglobulin fraction is the unique active pharmaceutical ingredient.
