Protein levels in urine from interferon-γ (IFN-γ) gene knockout (gko) graft recipients and B6D2F₁ hybrid control mice

Group	Day post-induction	Protein concentration (g/l)
IFN-γ gko	1	< 0·3
graft recipients*	3	< 0·3
	20	< 0·3
	50	< 0·3
	80	< 0·3
B6D2F1 controls	–	< 0·3

^*Three mice were tested on each day and all produced the same result. B6D2F₁ = (C57BL/6 × DBA/2)F₁ hybrid.
