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.
