Desthiobiotin是一种单环的、无硫的生物素，它与链霉素结合，具有几乎相同的特异性，但与生物素(Kd = 1011和1015M)相比，其亲和力更小。因此，在与自由生物素竞争驱替的温和条件下，可以很容易地、特别地从链霉毒素亲和树脂中分离出脱硫生物素。在生物样品的下拉实验中，desthiobiotin的软释放特性也有助于减少内源性生物素化分子的共提纯，这些分子在游离生物素的目标蛋白复合物的洗脱作用下仍与链球菌肽结合。

Desthiobiotin is a single-ring, sulfur-free analog of biotin that binds to streptavidin with nearly equal specificity but less affinity than biotin (K_d = 10¹¹ vs. 10¹⁵M, respectively). Consequently, desthiobiotinylated proteins can be eluted readily and specifically from streptavidin affinity resin using mild conditions based on competitive displacement with free biotin. For pull-down experiments with biological samples, this soft-release characteristic of desthiobiotin also helps to minimize co-purification of endogenous biotinylated molecules, which remain bound to streptavidin upon elution of the target protein complexes with free biotin.
