6441159-10	1984	J chain in IgA immunocytes was most intensely stained in sections of ethanol-fixed tissue denatured in acid urea (median score, 3) but was also well revealed after fixation with formalin, acetic acid-formol saline, Bouin"s fluid or Susa fixative (median scores, 1.8-2.0).	acid urea	103-112	joining chain of multimeric IgA and IgM	Homo sapiens	0-7	
6417474-1	1983	J-chain staining of IgA- and IgM-producing immunocytes was significantly enhanced when tissue sections were pretreated with acid urea, apparently because molecular unfolding exposed concealed J-chains.	acid urea	124-133	joining chain of multimeric IgA and IgM	Homo sapiens	0-7
