Induction of BK release by S. aureus (10¹⁰ CFU/ml) in protein-deficient plasma

Plasma	BK concn (pM)a	% of control concn
Normal (control)	2,272 ± 739	100
FXII depleted	114 ± 52	5
PK depleted	68 ± 40	3
HK depleted	136 ± 48	6
FXI depleted	4,589 ± 737	202
Fibrinogen depleted	2,022 ± 638	89

^aBK content of the supernatants was measured with an ELISA. Values are means ± standard deviations (n = 3).
