Bioconjugation, the process of covalently linking biomolecules, is a cornerstone of modern biotechnology, playing a vital role in drug development, diagnostics, and molecular imaging. Achieving stable and specific linkages requires reliable reagents, and Disuccinimidyl Glutarate (DSG) is a prime example of a versatile tool that simplifies this complex process. As a leading provider of high-quality biochemicals, we offer DSG to facilitate your bioconjugation strategies.

What is Bioconjugation and Why is it Important?

Bioconjugation involves joining two or more molecules, at least one of which is a biomolecule (like a protein, antibody, nucleic acid, or carbohydrate), using chemical linkers. This process is essential for creating:

  • Antibody-Drug Conjugates (ADCs): For targeted cancer therapy.
  • Labeled Proteins: For diagnostic assays or research imaging (e.g., fluorescently labeled antibodies).
  • Immobilized Enzymes: For biocatalysis or biosensors.
  • Peptide and Protein Conjugates: For vaccine development or therapeutic applications.

The success of bioconjugation hinges on the specificity and stability of the linker used.

Introducing Disuccinimidyl Glutarate (DSG) as a Bioconjugation Solution

Disuccinimidyl Glutarate, identified by CAS 79642-50-5, is a homobifunctional crosslinker. This means it has two identical reactive functional groups – N-hydroxysuccinimide (NHS) esters – at opposite ends of a molecule. The key features of DSG that make it ideal for bioconjugation include:

  • Amine Reactivity: The NHS ester groups react efficiently with primary amines (found in lysine residues and N-termini of proteins) under physiological pH conditions (typically pH 7-9). This reaction forms a stable amide bond, ensuring a strong and irreversible link.
  • Membrane Permeability: DSG can penetrate cell membranes, allowing for its use in intracellular bioconjugation and labeling experiments.
  • Spacer Arm: The five-carbon glutarate spacer provides a flexible linkage, which can help maintain the activity of the conjugated biomolecules by preventing steric hindrance.
  • Ease of Use: DSG is generally soluble in organic solvents like DMSO or DMF, making it convenient to prepare stock solutions for reactions.

When you buy DSG, you are acquiring a reagent that can reliably create covalent links between various biomolecules, enhancing their functionality or enabling their detection.
