title: Isolation of porcine, canine and feline IgG by affinity chromatography using protein A.
abstract: Isolation of porcine, canine and feline IgG has hitherto been achieved usually by DEAE-ion exchange chromatography and gel filtration. These procedures, however, are rather time-consuming, as they involve purification of IgG. Isolation of IgG by affinity chromatography on a column of protein A-Sepharose was attempted. IgG of all three animal species was very easily isolated with a high yield. In the absence of any other method that allows isolation of IgG of three animal species from a single column, the procedure proposed would be very useful.
