For scientists and developers working with proteins, antibodies, and nucleic acids, reliable crosslinking reagents are indispensable. Disuccinimidyl Glutarate (DSG), a homobifunctional crosslinker, is a popular choice due to its amine reactivity and membrane permeability. For those seeking to purchase this vital reagent, understanding the considerations around purity, price, and supply is key. As a leading manufacturer and supplier of high-quality biochemicals, we offer DSG with competitive advantages for researchers globally.

Understanding Disuccinimidyl Glutarate (DSG)

DSG (CAS 79642-50-5) features two N-hydroxysuccinimide (NHS) ester groups linked by a five-carbon glutarate spacer. These reactive ends efficiently form stable amide bonds with primary amines found in proteins and peptides. This capability makes DSG highly valuable for:

  • Stabilizing protein complexes: Essential for studying protein-protein interactions.
  • Antibody-drug conjugates (ADCs): Crucial for targeted drug delivery.
  • Chromatin Immunoprecipitation (ChIP): Facilitating the study of DNA-protein binding.
  • Surface immobilization: For biosensors and diagnostic assays.

Its membrane permeability also makes it suitable for intracellular applications.

The Critical Factor: Purity of DSG

When you are looking to buy DSG, the purity of the product is paramount. Impurities can lead to:

  • Non-specific reactions: Causing unintended crosslinking or modifications.
  • Reduced efficacy: Lowering the efficiency of desired reactions.
  • Inconsistent experimental results: Making it difficult to reproduce findings.

High-quality DSG typically has a purity of 97% or higher, often verified by techniques like quantitative NMR. As a dedicated manufacturer, we ensure our DSG meets these stringent purity standards, providing you with a reliable reagent for your critical applications.

Navigating DSG Price and Supply

The price of Disuccinimidyl Glutarate can vary based on factors such as purity, quantity, and the supplier’s manufacturing capabilities.
