6-Biotinamidohexanoic Acid - 1 G

6-Biotinamidohexanoic Acid contains an extended spacer arm which helps to minimize steric hindrance and carboxylic acid group which can react with amines via HATU to form stable amide bonds. With its uncharged, simple alkyl-chain spacer arm, this biotin compound is membrane-permeable and useful for intracellular labeling.
