Fig. 1From: Conferring extracellular matrix affinity enhances local therapeutic efficacy of anti-TNF-α antibody in a murine model of rheumatoid arthritisPlGF-2123-144 peptide conjugation with α-TNF. a PlGF-2123–144-α-TNF and unmodified α-TNF were analyzed by SDS-PAGE under reducing conditions with Coomassie blue staining. b Unmodified α-TNF and PlGF-2123–144-α-TNF were analyzed by MALDI-TOF MS. Abscissa is mass-to-charge ratio (m/z) and the ordinate is intensity of doubly charged ionsBack to article page
