In Vitro: Reactive Blue 2 is used as an ATP receptor antagonist and induces Ca2+ oscillations in HeLa cells. Reactive Blue 2 enhances a Ca2+ response to histamine that is linked to the PLC cascade. Reactive Blue 2 may activate the PLC cascade in an extracellular Ca2+-dependent manner and induce Ca2+ oscillations. The application of Reactive Blue 2 increases K+ secretion in a dose-dependent manner, and this increase is characterized as a peak followed by a partial relaxation to a steady-state. Reactive Blue 2 has antagonistic activities at P2Y4, and the antagonist potency at P2Y4 paralleled the potency of K+ secretion.The anthraquinone dye reactive blue 2 is found to be a potent inhibitor of a protein kinase isolated and purified from thylakoids. The mode of inhibition is noncompetitive, with a Ki of 8 μM for the membrane-bound kinase, and 6 microM for the purified kinase. The inhibitor does not modify the substrate preference of the endogenous kinase and could be removed from the membrane by washing. Reactive blue 2 selectively inhibits responses mediated via the P2ypurinoceptor, at least within a limited concentration range. In preparations where the tone has been raised with noradrenaline, ATP and 2-methylthio ATP, but not α,β-methylene ATP, produce relaxations of the vessel. These relaxations are inhibited in the presence of reactive blue 2. Reactive blue 2, at concentrations of 0.3-10 μM blocks the ATP-induced oscillation in a concentration-dependent manner.

文献和实验化氨基酸是多用途的介质,通过氨基酸与其互补蛋白间的亲和力,或者通过氨基酸的疏水性等性质,可以用于多种蛋白质、酶的分离纯化。例如L-精氨酸可以用于分离羧肽酶,L-赖氨酸则广泛的应用于分离各种rRNA。9.染料配体结合在蓝色葡聚糖中的蓝色染料Cibacron Blue F3GA是一种多芳香环的磺化物。由于它具有与NAD+相似的空间结构,所以它与各种激酶、脱氢酶、血清清蛋白、DNA聚合酶等具有亲和力,可以用于亲和层析分离。另外较常用的还有Procion Red HE3B等。染料作为配体吸附容量高、可以多次
