Griffithsin Protein, Griffithsia sp., Recombinant (X31S, His)

产品编号 TMPH-00777

Mixed specificity lectin with anti-HIV activity. Binds to HIV envelope glycoproteins, including exterior membrane glycoprotein gp120, and inhibits viral entry into cells. Binding to gp120 is dependent on gp120 being glycosylated, and is inhibited by mannose, glucose and N-acetylglucosamine.

常见问题解答
蛋白能保证活性吗?
我们有现货的产品,有活性数据的话会展示在官网生物活性那栏,没有数据的也不代表就一定没有活性,是我们还没有建立活性检测方法,没有进行测试,但是我们的蛋白都是优先按照有活性的方法去表达纯化的。
为什么某些重组蛋白溶液中还需要添加载体蛋白?
载体蛋白通常被用于提高蛋白的稳定性,防止蛋白在冷冻或解冻过程中粘附在管壁上。塑料管对蛋白有一定的吸附能力,这可能导致蛋白和管壁之间难以分离,导致溶液中蛋白的实际浓度下降,从而影响其活性。为减少这种损失,在长期保存重组蛋白 产品之前,建议添加常用的载体蛋白溶液,例如0.1% BSA(牛血清白蛋白)、5% HSA(人血清白蛋白)、10% FBS(胎牛血清)或 5% 海藻糖等。如果重组蛋白的浓度较低,强烈建议添加适量的载体蛋白。
重组蛋白有吗?
您需要什么种属的蛋白呢,对表达系统和标签有要求吗,用于什么实验?
为什么重组蛋白的体积和质量与预期不符?
蛋白冻干粉由蛋白原液冻干而来,冻干粉质量不等同于蛋白质量。由于冻⼲产品的体积大⼩受多种因素影响,包括冻⼲前缓冲液的组分、盐离⼦浓度以及产品本身的浓度等。冻⼲粉可能看上去很多,也可能肉眼不易观察到,这些都是正常现象,请您放心使用。在收到产品后,照常复溶、使用或分装储存即可。
如何将冻干的重组蛋白配置为储备液?
在打开盖⼦之前,先使用 10000-12000 rpm 的转速进行离心,20-30 秒,将附着在管盖或管壁上的冻⼲粉收集到管底,以避免损失。大多数蛋白可通过加入无菌蒸馏水来重新溶解。如果需要除水以外的其他稀释剂,产品 COA 中会对其进行说明。一般储备液浓度建议不要低于 100 μg/mL,分装储存避免反复冻融。

缓冲液If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
复溶方法
Reconstitute the lyophilized protein in sterile deionized water. The product concentration should not be less than 100 μg/mL. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
存储
Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
运输方式In general, Lyophilized powders are shipping with blue ice. Solutions are shipping with dry ice.
