NODAGA-LM3 TFA
NODAGA-LM3 TFA is a ligand that can cross the blood-brain barrier and targets somatostatin receptor SSTR2 with high affinity (IC50 = 1.3 nM). NODAGA-LM3 TFA does not trigger the internalization of SSTR2 and can inhibit agonist-induced internalization processes. NODAGA-LM3 TFA shows low uptake in normal tissues such as the liver and spleen, but high uptake in the lungs and blood pool. 68Ga-labeled NODAGA-LM3 TFA can serve as a PET imaging agent for well-differentiated neuroendocrine tumors, and is applied in studies related to small cell lung cancer and well-differentiated neuroendocrine tumors.

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.
