Nucleic Acid: 核酸(DNA/RNA)样品的浓度和纯度
Protein: 蛋白质A280(1Abs=1mg/mL,BSA,IgG,Lysozyme)
蛋白定量试剂盒法(Lowry法、BCA法、Bradford法)
Cell Culture:细胞溶液
UV-VIS: 紫外-可见全波长扫描(200-850nm)
Microarray: 微阵列样品检测,可同时检测荧光染料的浓度和核酸的浓度
测量操作
以移液枪吸取样品(0.3~2µL)滴加到检测平台上。
放下取样臂。
点击软件界面上的“Measure”按钮,即可得出样品参数(吸光度和浓度)和图表。
用干净的吸水纸擦去上下检测平台上的样品。
如需保存图表,可点击“Save Graph”按钮。
待全部样品测定结束后,点击“Show Report”按钮,已测样品的测定数据将出现在Excel表格中。
Smart never looked so good. The KS8000 4K SUHD TV features Quantum Dot Color technology, which covers you in our most superior picture yet, immersing you in whatever you’re watching. While HDR 1000 High Dynamic Range uses revolutionary technology to bring out details you’ve never seen in every foreground and background, Peak Illuminator Pro makes shades of every color pop. Plus, its Motion Rate 240 puts you on the pulse of every action sequence, while its flat, virtually bezel-less 360 design exudes elegance from every angle. If that’s not enough, we’ve enhanced its Smart Capabilities with the latest innovations and auto-sensing universal control, so it's insides are as extraordinary as its outsides.
