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。
