实验应用:抗体内化实验

产品评价: 我购买了CSB-EP360556CQR1用于抗体内化检测,使用了CUSABIO推荐的实验流程,实验流程很详细,服务也很周到。我用DT3C在不同的细胞中检测,并显示出不同的效果。我发现不同类型的细胞对DT3C的敏感度不同,其中一些细胞在抗体内化测定中显示出更好的结果。抗体内化的效率与抗原密度、抗体亲和力以及抗体和抗原结合表位密切相关。针对同一靶标的不同抗体也会表现出不同的内化效率。因此,建议在早期阶段可以多测试几个细胞。

实验应用:抗体内化实验

产品评价: 用CUSABIO的DT3C产品进行抗体内化效率检测,与其他方法相比,其mAb-DT3C复合物制备简单,且其抗体内化效率高于Mab-ZAP,性价比较高。我们会再次购买。

实验应用:细胞实验

产品评价: 我购买了DTC3重组蛋白用于杂交瘤细胞筛选,参考了某文献中的实验流程,结果很理想。具体实验流程如下: 用DT3C对杂交瘤细胞进行筛选:取96孔板,向每个孔中加入4μg/mL的DT3C(25微升),然后加入得到的杂交瘤的培养上清液(25微升),混匀后在室温下孵育30分钟。将NOR-P1细胞以2 x 10^5细胞/mL的浓度(RPMI培养基,含10%低IgG FBS (+))接种,然后在37℃的CO2培养箱中培养3天。培养后通过显微镜观察,确定粘附细胞数约为使用阴性对照抗体时粘附细胞数的25%或更少的孔为阳性。将选定的克隆进行一个或两个亚克隆步骤,以建立8个单克隆杂交瘤细胞系。

问答及客户评论

 常见问题解答
Q:

请给我们关于处理这个产品重组DT3C蛋白(CSB-EP360556CQR1)的建议,推荐的生物安全级别(BSL)是多少?

A:
该蛋白不具有传染性或致病性,可以像常规蛋白一样正常运输。如果您只是将此蛋白用于普通实验或检测,BSL-1可以满足需求。如果您的实验需要无菌操作,则需要BSL-2级别。
Q:

我对你们的产品DT3C重组蛋白用于抗体内化检测很感兴趣,想知道这对于胶质母细胞瘤是否有效?

A:
我们目前尚未进行相关实验验证。如果您有兴趣,我们可以提供一个小样本供您测试。
