Deposition of IgG and complement factor C3c in knee joints of mice at various times after induction of immune-complex- mediated arthritis

	IgG		C3c
Mouse strain	6 h	24 h	24 h
FcRγ-/-	128 ± 6	139 ± 4	152 ± 9
C57Bl/6 (control)	126 ± 4	140 ± 9	155 ± 7

IgG and C3c were studied immunohistochemically. Deposition was assessed using an image analyser to measure the mean amount of blue light, as a measure of staining intensity, passing through a defined area in the tissue. Data are means ± SD for six mice. Significance was evaluated using Student's t test.
