General description
2-亚氨基生物素是生物素的环状胍基类似物，在高 pH (> 9) 下对亲和素具有高亲和力，在低 pH (< 6) 下具有低亲和力。亚氨基生物素化的蛋白质选择性地包含在 pH 9-11 的亲和素柱内，可在 pH 4 洗脱或加入生物素洗脱。该技术可用于研究细胞表面蛋白，通过标记和选择性地从完整的人红细胞表面回收高碘酸盐敏感的成分。2-亚氨基生物素通过其胍基可逆性抑制 NOS（一氧化氮合酶）。它抑制 NO 的生物合成，了解这类重要酶的结合位点相互作用可能很重要。NOS 氧化 L-精氨酸的胍基氮生成一氧化氮和 L-瓜氨酸。
Application
已将 2-亚氨基生物素用作竞争性抑制剂，与链霉亲和素的生物结合位点结合，以恢复荧光信号。

Layered thin films composed of avidin and 2-iminobiotin-labeled poly(ethyleneimine) (ib-PEI) were prepared by a layer-by-layer deposition of avidin and ib-PEI on a solid surface, and the disintegration induced by changing environmental pH and adding biotin in the solution was studied.

The purpose of this study was to investigate whether combined inhibition of neuronal and inducible nitric oxide synthase (NOS) by 2-iminobiotin, free radical scavenging by allopurinol, and non-protein-bound iron chelation with deferoxamine improved cerebral oxygenation, electrocortical brain activity, and brain

UV resonance Raman (UVRR) spectroscopy is used to study the binding of biotin and 2-iminobiotin by streptavidin, and the results are compared to those previously obtained from the avidin-biotin complex and new data from the avidin-2-iminobiotin complex. UVRR difference spectroscopy

Affinity precipitation, especially secondary effect affinity precipitation, has repeatedly been suggested as a valuable technique for the biotechnical downstream process. The present lack of applications is related to the scarcity of predictable affinity macroligands and to the fact that rather

We have shown earlier that 2-iminobiotin (2-IB) reduces hypoxia-ischemia (HI)-induced brain damage in neonatal rats, and presumed that inhibition of nitric oxide synthases (NOS) was the underlying mechanism. We now investigated the effect of 2-IB treatment in P7 rat pups
