DOTA-NHS-ester can be used to modify human serum albumin (HSA) to produce DOTA-HSA. And DOTA-HSA is furtherly modified by Sulfo-SMCC (HY-D0975) to obtain DOTA-HSA-SMCC. DOTA-HSA-SMCC is conjugated to ZHER2:342 and the final product is DOTA-HSA-ZHER2:342. In a cell uptake assay, DOTA-HSA-ZHER2:342 is labeled by 64Cu, 64Cu-DOTA-HSA-ZHER2:342 (0.5-2 hours) slowly accumulates in the SKOV3 cells and reaches 0.71% of the applied activity at 0.5 h and the uptake increased to 1.58% at 2 h.

DOTA-NHS-ester, a versatile bifunctional chelating agent, finds widespread use in the biosciences, particularly in imaging and therapeutic realms. Explore its key applications:

Radioisotope Labeling: Delving into diagnostic imaging, DOTA-NHS-ester plays a pivotal role in creating radio-labeled biomolecules. By linking it to proteins, peptides, or antibodies, researchers can effectively bind metal radioisotopes for PET and SPECT imaging. This method enables precise localization and imaging of tumors, inflammation, or other pathological conditions in clinical diagnostics.

Theranostics: In the dynamic field of theranostics, DOTA-NHS-ester serves as a crucial component in generating conjugates that can both diagnose and treat diseases. Through its attachment to therapeutic molecules and labeling with therapeutic radioisotopes, targeted radionuclide therapy becomes a reality. This dual-action capability allows for real-time monitoring and treatment of diseases, significantly enhancing patient outcomes and treatment effectiveness.

Magnetic Resonance Imaging (MRI): Transcending conventional imaging techniques, DOTA-NHS-ester can be linked to gadolinium, a well-known MRI contrast agent, to elevate the quality of imaging results. By binding DOTA-NHS-ester to targeting molecules like cancer-specific peptides, more detailed and precise MRI scans can be achieved. This advanced imaging strategy is essential for accurate disease diagnosis and monitoring, pushing the boundaries of medical diagnostics.

Protein and Peptide Conjugation: Expanding its utility beyond imaging, DOTA-NHS-ester is instrumental in the conjugation of proteins and peptides for diverse research endeavors. This application facilitates the exploration of protein-protein interactions and aids in the delivery of therapeutic agents within cells, fostering advancements in drug development and various biomedical research initiatives.

The molarity calculator equation

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2
