SPR sensogram from faeces analysis. The flow cells were immobilised by recombinant Met proto-oncogene receptor (20 μg/ml), monoclonal anti-HGF (50 μg/ml) and HGF recombinant (3 μg/ml), respectively. The last channel (lowest line) was used as a reference to monitor the response due to buffer and unspecific interactions. Every other signal is the regeneration signal (1:1 combination of 1M Nacl and Glycine pH 2.0). The signals at time limits 12000, 12500, 14100 and 14600 seconds belong to patients with infectious gastroenteritis. The signals at time limits 13000 and 13500 seconds belong to faeces from healthy control. Please note the decline in the base line of the flow cells at the time limit 13000 when a faeces sample was injected that did not contain protease inhibitor.
