Abstract
A protein isolated from Pseudomonas maltophilia is found to possess an exposed, immunologically accessible protein which binds to the FC region of several species of immunoglobulins. The protein is found to bind both IgG and IgA immunoglobulins and is found to have an effective molecular weight of approximately 30,000 daltons. The protein is found to be useful in isolation of IgA immunoglobulins from biological mixtures. The protein makes IgA immunoglobulins available for further analytical techniques, including identifying bacteria which contain IgA binding proteins. Because of the increased availability of IgA immunoglobulins, it is possible to diagnosis and treat IgA-related diseases and their sources.
