Article Snippet: The following antibody dilutions were used: rabbit anit-SRS29B (formerly SAG1, 30 kDa) 1:5,000, rabbit anti-C4BP (alpha chain, 70 kDa) (AssayPro) 1:1,000, goat anti-C3 (C3, C3b, iC3b) and goat anti-Factor H (full length protein, 155 kDa) antibodies (CompTech) were both used at 1:20,0000, anti-rabbit HRP 1:10,000 (Sigma), and anti-goat HRP 1:5,000 (Santa Cruz Biotechnology, Inc.).
