Biotin-PEG2-acid

Biotin-PEG2-acid

This product is a bifunctional PEG2 linker with a biotin group for strong streptavidin/avidin binding and a terminal carboxylic acid for amide coupling. The short PEG2 spacer enhances solubility and reduces steric hindrance, making it especially ideal for bioconjugation and targeted labeling.

Key Features and Benefits:

• Biotin Moiety: Provides high-affinity binding to streptavidin and avidin systems.

• Carboxylic Acid Group: Couples with amines to form stable amide bonds.

• PEG2 Spacer: Improves solubility and minimizes steric hindrance in conjugation.

• High Purity: Ensures reproducible results in bioconjugation workflows.

• Dual Functionality: Combines affinity capture with versatile coupling chemistry.

Applications:

• Affinity Labeling: Biotinylation of proteins, peptides, and biomolecules.

• Bioconjugation: Attach biotin tags for detection or enrichment studies.

• Drug Delivery: Useful in targeted delivery systems with biotin recognition.

• Surface Functionalization: Modify nanoparticles, hydrogels, or biosensors with biotin.

Storage and Handling:

• Storage: Store at –20 °C, protected from light and moisture.

• Handling: Use anhydrous solvents (e.g., DMF, DMSO) to maintain reactivity.

This product combines biotin affinity binding with carboxyl reactivity, offering a compact PEG linker specifically for precise bioconjugation and targeting strategies.
