      Biotin-PEG-NHS,MW:2000 英文產品介紹(含結構式圖)


      Biotin PEG NHS, MW 600, 1000, 2000, 3400, 5000, 10k, 20k
      Catalog Numbers: PG2-BNNS-600, 1k, 2k, 3k, 5k, 10k, 20k.
      Synonym: NHS PEG Biotin, Biotin NHS PEG, Succinimidyl PEG Biotin


      Description:
      Biotin PEG NHS is one of Nanocs’ amine reactive biotin
      polyethylene glycol derivatives that have a succinimidyl
      NHS ester on one terminus of PEG chain and a biotin on
      the other PEG end. Biotin is a small bioactive molecule
      that has high affinity toward avidin or streptavidin.
      Biotin/streptavidin system has been widely used in
      molecule detection, bioassays and drug delivery
      applications. NHS reacts quickly with primary amine
      groups at alkaline pH to form a stable amide bond.
      Reaction between NHS and amine enables quick and
      efficient conjugation of biotin tag to proteins, antibodies,
      peptides, particles and many other materials. PEG linker
      between biotin and NHS group offers better water
      solubility, less steric hindrance and enhanced stability.


      Product Structure:


      Product Specifications:

      Composition: Biotin PEG NHS.
