C1q and MBL bind modified forms of LDL. LDL, OxLDL, AcLDL, or BSA control protein were immobilized on a plate and incubated with 0.5–150 μg/ml C1q (A) or 0.5–80 μg/ml MBL (B). Binding was assessed by ELISA using the OPD substrate with signal absorbance measured at 405 nm. Data are from a single experiment, performed in duplicate wells, representative of three individual experiments.
