Biological Activity: GPC3 targeting peptide 2 is a glypican-3 (GPC3) targeting peptide that binds specifically to GPC3 with a Kd of 39.5 nM. GPC3 targeting peptide 2 can be conjugated to IRDye800 via a GGGSC linker for near-infrared fluorescence and photoacoustic imaging, with a tumor-to-adjacent liver fluorescence intensity ratio of approximately 2-fold. GPC3 targeting peptide 2 shows high specificity for immunofluorescence staining of HCC specimens. GPC3 targeting peptide 2 can be used in studies related to GPC3-targeted molecular imaging and early detection of hepatocellular carcinoma[1][2].
