- What kind of controls should I use with the alamarBlue™ Cell Viability Reagent?
- How does media affect the PrestoBlue™ Cell Viability Reagent?
- How do I prepare dead cell controls for LIVE/DEAD™ cell viability assays?
- Can I store the stock solutions of the CellTrace™ reagents and how do you recommend storing them?
- Can I substitute reagents from the Click -iT™ Plus kits into the original Click-iT™ kits or vice versa?
- What causes trypan blue to form a precipitate?
- It looks like my alamarBlue™ dye has precipitated. What should I do?
- I am using PrestoBlue™ reagent and am observing high background fluorescence values. What should I do?
- I am using the CellTrace™ Cell Proliferation reagents and am not obtaining good separation of my cell generation peaks. How can I improve the peak separation?
- I trypsinized my adherent cells and labeled with annexin V, and now my flow data is showing a high percentage of apoptotic cells even for control, untreated cells. What is the problem?
