  • HY-P11590
    WGYRGFYC
    		Ligand
    WGYRGFYC (WC8) is a selective HER2-targeting peptide that binds specifically to HER2 by mimicking the antigen-binding site of trastuzumab. The DOTA precursor of WGYRGFYC has a KD of 61.20 nM for HER2. WGYRGFYC enables specific and highly sensitive detection of HER2 expression in HER2-positive breast cancer cells and tumor tissues, and monitors the dynamic downregulation of HER2 expression. WGYRGFYC rapidly distributes to target tissues and is efficiently cleared from non-target tissues via the kidneys, generating an ideal tumor-to-background ratio in imaging; it is a component of the PET radiotracer Ga-DOTA-WC8. WGYRGFYC exhibits no significant cytotoxicity in breast cancer cells, and can be used for non-invasive imaging diagnosis and therapeutic efficacy evaluation of HER2-positive breast cancer.
  • HY-P11613
    DOTA-WC8
    		Ligand
    DOTA-WC8 is a HER2-targeting peptide probe with a KD of 61.20 nM. 68Ga-labeled DOTA-WC8 serves as a PET imaging agent for the specific identification of HER2-positive breast cancer. DOTA-WC8 is applicable to breast cancer-related research.
  • HY-P10792A
    HYNIC-H6F
    		Ligand
    HYNIC-H6F is a SPECT imaging probe with binding specificity for human epidermal growth factor receptor 2 (HER2) domain II (IC50 = 11 nM). HYNIC-H6F accumulates in HER2-positive breast cancer xenografts via receptor-mediated uptake, while shows low uptake in HER2-negative breast cancer xenografts. HYNIC-H6F enables non-invasive detection of HER2-positive breast cancer in mouse models and allows evaluation of HER2 expression levels without blocking interference. HYNIC-H6F can be used in breast cancer-related research.
