Serum Levels of Joining Chain-Containing IgA1 Are Not Elevated in Patients with IgA Nephropathy

Table 2

Comparison of the percentage of mIgA1, dIgA1, and pIgA1 in purified IgA1 between patients with IgA nephropathy and healthy subjects.

	pIgA1 (%)	dIgA1 (%)	mIgA1(%)	Small fragments (%)
NC	1.36	10.67	75.77	12.20
IgAN	0.20	4.96	84.33	10.52

IgAN: IgA nephropathy; NC: normal control; pIgA1: polymeric IgA1; dIgA1: dimeric IgA1; mIgA1: monomeric IgA1.
