Hello,
Thank you for reaching out with your VWorks question.
In general, you can either perform this as a series of tasks as you have already done or make use of loops and scripting to condense the protocol. As you noted, using loops will continuously…
On Thursday, June 6, we presented the third installment of our GC Live series. Our speakers discussed how the new single-channel 8850 GC can help labs maximize productivity, efficiency, and uptime.

Thank you for contacting Cell Analysis Technical Support. This will depend on your instrument type. See this link as well as the screenshot below. Keep in mind that these ranges are pre-normalization.
For Cell Mito stress test, Seahorse Cell Mito Stress Test Kit, the recommended working concentrations are 1.5 µM for Oligomycin and 0.5 µM for Rot/AA. The FCCP concentration needs to be optimized (0.5 µM-2 µM). The optimal final compound concentration…
In general, the %CV across a group and from plate to plate should both be < 20%. Higher CVs in this case was due to edge effect on outside of the plate.
