Confirmation of putative receptor-binding sites on the ligands using synthetic analogues by semi-quantitative ELISA. Framed reagents were coated into microtiter wells. Data present means of triplicates with ± S.D. CB – coating buffer; hBMECs – protein extract of human brain microvascular endothelial cells; DIII-1 – GTTYGVCSK-biotin; DIII-2 – VLIELEPPFGDSYIVVGRK-biotin; NadA-1 – AATVAIVAAYNNGQEINGFKAGETIYDIGEDGTITQK-biotin; NadA-2 – LADTDAALADTDAALDETTNALNKLGENITTFAEETK-biotin. Coating of DIII-2 synthetic peptide was very low on the Nunc™ ELISA plate, that is why detection of coated DIII-2 on the plate (input control) with streptavidin-HRP conjugate was weak. Please note that all wells were blocked with blocking buffer after overnight coating. Interaction was detected with streptavidin-HRP conjugate.
