容易。该设备具有直观的磁性设计，用户更换插孔非常简单。但是，我们强烈建议用户在更换或洗涤时，小心处理插孔（按插槽上的指示操作），其他两个插孔在不使用时应保存在底部的托盘中。
除了iBind Flex卡片的宽度是iBind卡片的1.7倍之外，iBind Flex卡片背面还印有对齐线，它们会在加入溶液时出现，有助于正确水平摆放多张小型或垂直剪切膜条。
两种标准和荧光检测溶液的配方是相同的。唯一的不同点是产品供应量不同，iBind Flex溶液试剂盒足够供10块中型、20块小型或60块垂直剪切膜条使用。
不建议这样使用，从顶部到底部不均匀流动产生的电势，可能导致穿过水平剪切膜条产生梯度信号强度。
适用，可转印单张小型印迹膜或最多3块垂直剪切膜条。但是，当使用小型或多膜条插槽时，未与卡片接触的孔应为空的。
可以。无论是否使用小型或多膜条插槽，空孔都应与卡片保持接触，应用水填充以确保所有溶液流过卡片。
当使用iBind Flex蛋白质免疫印迹系统和LI-COR Odyssey成像系统时，请采用使用手册（https://assets.thermofisher.com/TFS-Assets/LSG/manuals/ibind_flex_man.pdf）第14页的实验方案。我们不建议使用LI-COR溶液。
我们可提供iBind Flex溶液试剂盒和iBind Flex荧光检测（FD）试剂盒。对于标准化学发光或发光检测，我们建议使用iBind Flex溶液试剂盒（货号SLF2020，SLF2020X4）；对于荧光检测，我们建议使用iBind Flex荧光检测（FD）试剂盒（货号SLF2019）。
如果PVDF膜是干燥的，则在浸泡于iBind Flex溶液/ iBind Flex荧光检测（FD）溶液之前，需要使用100%甲醇预活化，并用蒸馏水润洗。刚刚转印完毕并转移至在iBind Flex溶液/ iBind Flex荧光检测（FD）溶液中的PVDF膜无需活化。
•每次使用后，用流水冲洗iBind Flex插槽，在下一次使用前将插槽晾干。
•小心处理插槽。
•将未使用的插槽保存于iBind Flex蛋白质印迹设备的抽屉中。
•为延长iBind Flex蛋白质印迹设备弹簧的使用寿命，保存设备时应将弹簧锁解锁，并打开盖子，如使用手册(https://tools.thermofisher.com/content/sfs/manuals/ibind_flex_man.pdf)第28页所示。
将膜置于iBind Flex溶液/ iBind Flex荧光检测（FD）溶液中浸泡至制备抗体稀释液之前，足以完成对膜的封闭。不需要将膜在封闭液中封闭过夜。加入一抗之前，膜会在iBind Flex溶液/ iBind Flex荧光检测（FD）溶液中额外受到封闭。
我们不建议使用您自己的溶液。iBind Flex溶液和iBind Flex荧光检测（FD）溶液具有特殊的粘稠度，并且针对iBind Flex蛋白质免疫印迹系统的顺序侧流原理进行了优化。我们不能对任何其他溶液的性能进行保证。

iBind蛋白质免疫印迹系统是一台自动化免疫检测设备。该设备无需外接电源，利用机械压力使免疫检测试剂发生顺序侧流（SLF），从而自动完成免疫印迹检测中所有的封闭、抗体孵育和洗涤步骤。
有两种iBind蛋白质免疫印迹系统可供选择：包括1）传统iBind蛋白质印迹设备，可容纳1块小型印迹膜，以及2）iBind Flex蛋白质印迹设备，可同时容纳1或2块小型印迹膜、1块中型印迹膜或最多6块垂直剪切膜条（用于不同抗体）。Yes. When using a conjugated primary antibody and no secondary antibody, add the diluted primary antibody to well 1 and replace diluted secondary antibody (well 3) with 1X iBind Flex/iBind Flex FD Solution. Alternatively, for faster time to results, add the diluted primary antibody to well 1, leave wells 2 and 3 empty, and add 1X iBind Flex/ iBind Flex FD Solution to well 4. This procedure will save time (~60 min) but may result in higher background.

To strip and reprobe your blot processed using the iBind Western Device or iBind Flex Western Device, first strip the blot outside the system using your preferred protocol. After the stripping protocol, wash the blot in distilled water for 5 min. Reblocking is unnecessary as the iBind Solution will perform this step during reprobing. Finally, reprobe with new antibodies using the iBind Western Device or iBind Flex Western Device, starting with the membrane preparation step.

Yes, for each midi blot, mini blot, or vertically cut strip, prepare appropriate primary antibodies together in a single tube of iBind FD/ iBind Flex FD Solution, Prepare appropriate secondary antibodies together in a different tube of iBind FD/ iBind Flex FD Solution. Do not mix primary and secondary antibodies prior to loading in the device. All primary and secondary antibodies should be diluted according to the recommendations outlined in the user manual or quick reference card. When detecting several targets of the same species, the same concentration of secondary antibody can be used as when detecting one target. There is no need to increase the concentration for each additional target. Load multiplexed antibodies into the device as normal.
Caution: Consider cross-reactivity of secondary antibodies when multiplexing (e.g., rabbit anti-goat IgG and goat anti-mouse IgG are likely to cross-react).

Yes. Due to an intuitive magnetic design, it is very simple for the user to change the well inserts. However, we highly recommend the user handle the well inserts with care (as engraved on each insert) when changing or washing, and store the other two well inserts in the convenient underside tray when not in use.

The formulations are identical for both the standard and Fluorescent Detection (FD) solutions. The only difference is in the amount supplied, so the iBind Flex Solution Kits are sufficient for 10 midi, 20 mini, or 60 vertically cut strip blots.

It is not recommended due to the potential for non-uniform flow from top to bottom which could result in a gradient signal intensity across horizontally cut strip blots.

Yes, to run a single mini blot or up to three vertically cut strip blots. However, when using the Mini or Multi-Strip Inserts, wells not in contact with the card should remain empty.

Yes. Whether using the Mini or Multi-Strip Inserts, empty wells are still in contact with the card and should be filled with water to ensure proper flow of all solutions across the card.

If the PVDF membrane has dried up, it is important to pre-activate it with 100% methanol and then rinse in distilled water before immersing it in iBind Flex Solution/iBind Flex Fluorescent Detection (FD) Solution. It is not necessary to activate a PVDF membrane that has just come out of the transfer and moved into iBind Flex Solution/iBind Flex Fluorescent Detection (FD) Solution.

- Rinse the iBind Flex well inserts under running water after each use and allow the well inserts to dry before additional usage.
- Handle well inserts with care.
- Store unused well inserts in the drawer in the iBind Flex Western Device.
- To maximize the life of the springs in iBind Flex Western Device, store the device with latch unlocked, and the lid open as shown on Page 28 of the manual (https://tools.thermofisher.com/content/sfs/manuals/ibind_flex_man.pdf).

It is sufficient to block the membrane in iBind Flex Solution/ iBind Flex Fluorescent Detection (FD) Solution for the time prior to making antibody dilutions. It is not necessary to block the membrane overnight in the blocking solution. The membrane will be subjected to additional blocking in the iBind Solution/ iBind Flex Fluorescent Detection (FD) Solution before primary antibody reaches the membrane.

We do not recommend using your own solutions. The iBind Flex Solution and iBind Flex Fluorescent Detection (FD) Solution have specific viscosity and are optimized for the sequential lateral flow that is the principle of the iBind Flex Western device. We cannot guarantee the performance with any other solutions.

iBind Western Systems are benchtop devices that automate immunodetection steps. These devices use no external power source, and rely on mechanical pressure to generate sequential lateral flow (SLF) of immunodetection reagents to perform hands-free blocking, antibody binding, and washes for western detection workflows.
Two iBind Western Systems are available:
i) containing the original iBind Western Device, which accommodates one mini blot at a time
ii) containing the iBind Flex Western Device, which accommodates one or two mini blots, one midi blot, or up to six vertically cut membrane strips (for separate antibodies) at a time.
