Biotin-PEG3-Azide is a click chemistry biotinylation reagent designed for labeling alkynylated molecules like DNA, oligonucleotides, and proteins. This reagent uses copper-catalyzed or copper-free click reactions to attach biotin, enabling efficient conjugation. Once labeled, biotinylated biomolecules can bind to avidin or streptavidin for purification and detection.
Key Features:
- Click Chemistry Labeling: The azide group allows rapid biotinylation through click reactions, providing versatile options for bioconjugation.
- Hydrophilic PEG3 Linker: Enhances solubility and separates the biotin from the target molecule, promoting efficient binding with streptavidin.
- High Affinity: Biotin-PEG3-Azide’s structure supports strong interactions with streptavidin or avidin, ideal for various purification and detection applications.
Biotin-PEG3-Azide is widely used in research for labeling, tracking, and isolating biomolecules, making it an essential tool in modern biochemical and diagnostic assays.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
