TAMRA-Azide-Desthiobiotin

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.

Desthiobiotin是一種單環(huán)、無硫生物素的類似物，它與鏈霉菌素結(jié)合的特異性幾乎相同，但親和力卻不如生物素(Kd分別為1011和1015M)。因此，在與自由生物素競爭驅(qū)替的溫和條件下，可以很容易地、特別地從鏈霉毒素親和樹脂中分離出脫硫生物素。在生物樣品的下拉實驗中，desthiobiotin的軟釋放特性也有助于減少內(nèi)源性生物素化分子的共提純，這些分子在游離生物素的目標(biāo)蛋白復(fù)合物的洗脫作用下仍與鏈球菌肽結(jié)合。
