Bioconjugation, the process of covalently linking biomolecules to other molecules, is fundamental to advancements in diagnostics, therapeutics, and biochemical research. A key component in achieving efficient and stable bioconjugations is the use of high-quality reagents like DOTA-NHS Ester (CAS: 170908-81-3). As a specialized manufacturer and supplier of fine chemicals, we are committed to providing the essential building blocks that empower scientific innovation. Our high-purity DOTA-NHS Ester, produced in China, is designed to meet the exacting demands of the biotechnology and pharmaceutical industries.

DOTA-NHS Ester is a bifunctional molecule, featuring a DOTA chelator at one end and an N-hydroxysuccinimide (NHS) ester at the other. The NHS ester moiety is highly reactive towards primary amines, commonly found in lysine residues of proteins and peptides, or at the N-terminus. This reaction forms a stable amide bond, effectively attaching the DOTA chelator to the biomolecule. The DOTA group is renowned for its exceptional ability to chelate various metal ions, including those used in medical imaging and therapy, such as Gadolinium for MRI, or radiometals like Gallium-68 or Lutetium-177 for PET and targeted radiotherapy. When researchers seek to buy DOTA-NHS Ester, they are looking for a reagent that ensures successful and stable conjugation.

The efficiency and specificity of bioconjugation are directly influenced by the purity and reactivity of the NHS ester. Impurities can lead to side reactions, reduced conjugation yields, and potentially compromised biological activity of the final conjugate. Our stringent manufacturing processes ensure that our DOTA-NHS Ester boasts high purity, thereby maximizing the efficiency of amine coupling and minimizing unwanted reactions. This is critical for applications in antibody-drug conjugates (ADCs), peptide-based therapeutics, and advanced diagnostic probes, where the precise attachment of payloads is vital.

For researchers and procurement specialists, sourcing reliable chemical suppliers is a strategic imperative. Partnering with a manufacturer in China like ours offers access to cost-effective, high-quality DOTA-NHS Ester without compromising on performance.
