Fig. 2From: A TAT-conjugated peptide inhibitor of polo-like kinase 1 for in vivo tumor imagingHPLC profiles. HPLC showed retention time of 1 (a) and 2 (b). HPLC (Vydac C18 column) performed on a linear gradient over 30 min of acetonitrile/0.1% TFA from 5% to 90% at a flow rate of 1.5 mL/min. UV detection was carried out under a wavelength of 230 nmBack to article page
