DOTA-LM3（Cat No.:I041118）is a peptide-based compound conjugated with the DOTA (1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid) chelator, which is used in radiolabeling for molecular imaging. It is typically utilized in positron emission tomography (PET) and single-photon emission computed tomography (SPECT) to visualize and track specific biological targets, such as cancer cells. The DOTA chelator allows the attachment of radiometals, enabling targeted imaging of tumors or other pathological tissues. DOTA-LM3 is particularly useful in oncology, where it helps assess tumor burden and monitor the effectiveness of targeted therapies in cancer treatment.
