Inhibition of anti-heparan sulphate antibody binding by pre-incubation with growth factors

PatientPre-incubation with IGF-1Pre-incubation with HGF
  • IGF: insulin-like growth factor; HGF: hepatocyte growth factor; COPD: chronic obstructive pulmonary disease. Cryosections were pre-incubated with growth factors IGF-1 or HGF, followed by incubation with HS4C3 or AO4B08. Bound antibodies were visualised. An overall inhibition was seen for HS4C3 after pre-incubation with HGF. After pre-incubation with IGF-1, HS4C3 was slightly inhibited but AO4B08 was not. +: comparable intensity to non-pre-incubated cryosections; +/−: reduced intensity compared with non-pre-incubated cryosections; −: completely absent staining.
