不兼容，请遵循Tempus系统的RNA分离方法。Tempus收集管与RiboPure试剂盒不兼容。
请访问我们的网站（https://www.thermofisher.cn/cn/en/home/references/ambion-tech-support/rna-isolation/general-articles/tips-for-working-with-blood-samples.html），查看处理血液样品的技巧。
不能，出厂实验方案不能编辑，但是您可以使用“另存为”功能对其重命名，然后将它作为一个新的版本来编辑。
对于核酸提取，我们建议使用我们的MagMAX试剂盒和MagJET试剂盒。其它大小在0.5到10 µm间的磁珠应该也可以使用。但是，您需要自己用Thermo Scientific BindIt软件编写您自己的KingFisher实验方案，并自己验证/优化这一实验方案。
可以，可将样品分装。在进行下一步之前，设置程序使得磁头可以从多个孔内收集样本。确保不要过量加样。
可以，反应体积可以扩大，并且所有其它体积（例如洗涤体积）需要以相同倍数扩大。除非板的容积允许，我们强烈建议反应体积扩大不应超过2倍。
是的，所有MagMAX试剂盒都能用于KingFisher Flex 磁珠处理仪。
No, please follow the RNA isolation methods described with the Tempus system. The collection tubes are not compatible with the RiboPure kit.
Please visit our website for tips for working with blood samples.

No, the RNA Binding Beads are not available as a stand-alone product.
Some bead carryover is common and has not been documented to affect downstream assays. The most common cause of bead carryover is too much input sample. The best way to determine if the sample amount is the cause of the issue is to run PBS with Xeno (artificial DNA/RNA) in the lysis buffer and then check if there is still bead carryover. If that is not the cause, the initial sample may require special processing, such as bead beating or liquification. If there is still bead carryover without the original sample, and in particular, if the carryover is present in the same wells for multiple runs, then this may be an instrument alignment issue.
Plastic consumables need to be purchased separately in order to use the MagMAX reagents on the MagMAX Express-96 or a KingFisher instrument. The particular consumables and the amount required will vary by kit and protocol so please check the user guide for the particular MagMAX kit to be sure that all required plastic consumables are available prior to sample processing.
The best place to download KingFisher Flex and KingFisher Duo Prime protocols for a particular MagMAX kit is the relevant MagMAX kit product page. The Bindlt script protocol (.bdz) files can be found under the Documents>Product literature section.
Yes, reaction volumes for MagMAX kits can be scaled up. In general, the amount of MagMAX reagents should be scaled up proportionally for the increase in sample input amount. Please see the specific kit user guide for any recommendation. If none are included, then optimization may be necessary.
Addition of BME (2-mercaptoethanol) to the lysis buffer of MagMAX kits is fine. This can be beneficial with more RNase-rich samples like certain types of tissues.
In general, we recommend adding 0.3 µL BME per 100 µL of lysate.
The user guide for our MagMAX for Stabilized Blood Tubes RNA Isolation Kit, compatible with Tempus Blood RNA Tubes, states that you can stop after the RNA resuspension step by storing the resuspended crude RNA pellet on ice for up to 4 hours.
Please see page 18 of the following user guide: https://assets.thermofisher.com/TFS-Assets/LSG/manuals/cms_084749.pdf.
Equine whole blood has been successfully tested using this system, getting RINs around 9. Bovine blood should work similarly since there is not much of a difference between the two species for RNA isolation from whole blood, but this has not been tested. The protocol would be the same as the user guide and samples should be mixed vigorously immediately after blood is drawn into the tube for at least 10 secs, incorporating tube inversion to be sure the sample is stabilized.
No, only certain MagMAX kits are compatible with Tempus/PAXgene stabilized blood samples. We recommend using only MagMAX kits that are designed for blood samples stored in the designated RNA blood tubes for the kit. For PAXgene tubes, the compatible kit is the MagMAX for Stabilized Blood Tubes RNA Isolation Kit, compatible with PAXgene Blood RNA Tubes (Cat. No. 4451894). For Tempus tubes the compatible kit is the MagMAX for Stabilized Blood Tubes RNA Isolation Kit, compatible with Tempus Blood RNA Tubes (Cat. No. 4451893).
No, manufactured protocols are locked for editing, but they can be renamed using the ‘save as' function and edited as a new version.
For nucleic acid extraction, we recommend using our MagMAX kits and MagJET kits. Other magnetic beads should work well as long as they are 0.5 to 10 µm in size. However, you will have to write your own KingFisher protocols using the Thermo Scientific BindIt software and validate/optimize the protocol on your own.

Yes, this can be done by sample splitting. Set the protocol so that the magnet will collect samples from multiple wells before continuing to the next step. Be sure not to overload.

Yes, reaction volumes can be scaled up, and all other volumes (i.e. wash volumes) will have to be increased by the same fold difference. It is generally not recommended to scale up reaction volumes more than 2-fold unless the plate's volume capacity will allow it.
Yes, all MagMAX kits can be used with the KingFisher Flex Magnetic Particle Processor.
