8926055-10	1996	Using a novel assay for IgA1 protease activity upon sodium dodecyl sulfate-polyacrylamide gel electrophoresis, we demonstrated that the secreted IgA1 protease was present in several different molecular forms ranging in size from approximately 135 to 220 kDa.	Sodium Dodecyl Sulfate	52-74	immunoglobulin heavy constant alpha 1	Homo sapiens	24-28

3093370-1	1986	Eight human IgA1 myeloma proteins were analysed by SDS-PAGE.	Sodium Dodecyl Sulfate	51-54	immunoglobulin heavy constant alpha 1	Homo sapiens	12-16	
1880427-4	1991	The IgA1 preparation was apparently homogeneous by SDS-PAGE but contained a trace of C1-inhibitor and a second protein detected by immunoelectrophoresis.	Sodium Dodecyl Sulfate	51-54	immunoglobulin heavy constant alpha 1	Homo sapiens	4-8	
1713195-4	1991	Analysis of silver-stained sodium dodecyl sulfate-polyacrylamide gels of outer membranes indicated that there were two outer membrane proteins of 78 and 68 kDa which were cleaved by IgA1 protease in vitro in GCM 740 (a wild-type strain) and in two isogenic IgA1 protease-negative variants.
