Binding of human SAP to bacteria in vitro

Bacterial species	SAP binding (molecules of SAP bound per bacterial cell)
E. coli O111:B4 (smooth)	<5 × 102
E. coli J5 (Rc)	2.1–6.0 × 104
E. coli F515 (Re)	2.8 × 104
S. pyogenes H305	2.8–6.0 × 103
N. meningitidis clinical isolates, types A, B, and C	4.3 × 103 to 1.7 × 104
N. meningitidis H44/76 (LPS-sufficient wild type)	4.9 × 104
N. meningitidis H44/76[pHBK30] (LPS-deficient mutant)	2.8–4.0 × 104

These representative values may vary by up to 2-fold between different cultures of the same organism.
