Biotin-PEG3-acid
This product is a high-purity biotin derivative with a PEG3 spacer and a terminal carboxylic acid. The PEG3 spacer specifically enhances solubility, reduces steric hindrance, and improves biotin accessibility for conjugation to biomolecules and surfaces.
Key Features
-
Biotin moiety for high-affinity binding to streptavidin/avidin
-
Terminal carboxylic acid for amide bond formation
-
PEG3 spacer for improved solubility and reduced steric interference
Applications
-
Biotinylation of proteins, peptides, and antibodies
-
Surface functionalization for affinity assays
-
Development of biotin-based detection and capture systems
Storage and Handling
-
Store at –20 °C, protected from light and moisture
-
Allow to warm to room temperature before opening
