Fig. 1From: In vivo optical imaging of early osteoarthritis using an antibody specific to damaged arthritic cartilageImmunohistochemistry of destabilised medial meniscus (DMM) sections at 4 and 8 weeks after surgery. Paraffin sections of knee joints 4 and 8 weeks after DMM surgery were probed with Cy5.5-1-11E or control Cy5.5-C7 scFvs and visualised under the confocal microscope. The Cy5.5 label is false coloured in red, and the anti-heparan sulphate proteoglycan antibody detected with Alexa-488 labelled secondary antibody coloured in green. The consecutive section was counterstained with Safranin O. Scale bar = 20 μmBack to article page
