Biotin itself is a free small molecule. In biological experiments, it often needs to be covalently labeled on proteins or biomaterials to make use of the strong specificity and affinity of BAS system to amplify signals, detect quantitatively and purify samples. This process of labeling biotin is called biotinylation. ***生物 provides a variety of biotinylation reagents, which can selectively label the amine group, thiol group, carboxylic acid and other groups on the target macromolecules.生物素本身是个游离的小分子，在生物实验中常常需要把它以共价键的方式标记到蛋白或生物材料上，从而来利用BAS系统强大的特异性和亲和力来信号放大，定量检测和样品纯化。这个标记生物素的过程就叫生物素化。***生物提供各种生物素化试剂，可选择性的标记目标大分子上的胺基，巯基，羧酸等基团上。Biotin-Dadps-N3  |  Chinese and English aliases英文名称：DADPS Biotin AzideBiotin-Dadps-azideBiotin-PEG4-amino-t-bu-dadps-C6-azide中文名称：DADPS叠氮生物素Biotin-Dadps-N3  |  Physical parametersCASNumber：1260247-50-4Molecular formula：C43H67N7O9SSiMolecular  weight：886.2Purity：95%Appearance：Light yellow or or white solidStorage conditions：-20 ℃, cool, dry, well ventilated, stored in a dark warehouseSolubility：Soluble in most organic solvents, soluble in waterCustomized：CustomizableStructural type：
