RT112 shows growth factor binding activity. (a) Native-PAGE of RT112 in a ligand-free (−) and FGF1-incubated (+) state. Samples are shown under GFP-fluorescence. The ladder (M) was composited from a visible image of the same gel. (b) Mass photometry histograms of ligand-free (blue) and FGF1-incubated (cyan) RT112. Major peaks from both histograms are labelled in the respective colours, and counts are on the left and right respectively. Statistical significance was determined using a twinned t-test between the mean counts for each dataset.
