The clot thickens: An α2-antiplasmin peptide fragment labeled with a near-infrared fluorochrome or a paramagnetic reporter (see figure) can be used for imaging blood clot formation. A thrombosis-specific probe was developed based on blood coagulation factor XIII transglutaminase but the approach could be extended to other transglutaminases involved in diseases such as cancer, neurodegenerative diseases and celiac disease. The use of near-infrared fluorescence avoids the difficulty of background absorbance encountered when light imaging is used for blood imaging.
