Synonym: NHS PEG Biotin, Biotin PEG Succinimidyl ester, Biotin PEG5000 NHS, NHS PEG5000 Biotin Biotin PEG NHS is one of reactive PEG biotin reagents that can be used to label proteins, antibodies, small molecules or surfaces via their available amine groups. NHS reacts quickly with primary amine groups under alkaline pH to yield a stable amide bond. This reaction allows rapid attachement of biotin tag to targeted molecules or material surfaces. Resulted biotin tag can be easily detected with avidin or streptavidin. PEG linker between NHS and Biotin offers better water solubility, flexible linker structure and enhanced stability.  Physical Properties: Form: Solid Color: White Solubility: Soluble in aqueous buffer Reactive group: NHS (succinimidyl ester) Reactive to: Primary amine group (-NH2) Applications: Biotin conjugation (Biotinylation) Purity: >95% Storage Conditions: Store at -20 0C. Desiccate. Avoid frequent thaw and freeze. References: Click here to check hundreds publications using PEGs.
