Polyclonal antisera from immunized hosts are lipid extracted to improve clarity, salt fractionated, dialyzed against phosphate buffered saline containing sodium azide, and freeze-dried. Antisera against whole serums are obtained by immunizing host animals with whole serum. Antisera against whole IgG molecules [i.e. Anti-IgG (H+L)] are recommended for bridging PAP to primary antibodies.
Our range of antisera to immunoglobulins, whole serums and enzymes has been rationalized according to customer demand. Existing inventory is still available for some discontinued products, however we cannot produce more on request.
