@@ajarieger_flow There is a question about the working flow of the Fortessa cytometer. For example, When I look at the spectrum viewer, I found laser 355 and laser 488 could excite fluorochromes, such as FITC, PE, and PE-cy7, though laser 488 could produce higher emissions of these three fluorochromes. I am wondering how the cytometer to avoid this issue.

@@ajarieger_flow There is another question about the compensation of fixable viability dye 506. The manufacturer recommends using live/dead cell mix to do compensation for that. However, my labmate told me a tricky way to use BV510 conjugated antibody instead of fixable viability dye for beads to do the compensation without using cells. Although I found the excitation and emission of fixable viability dye 506 and BV510 are almost the same in the spectrum viewer, it works for my work, I am still wondering is it good to do it? Because you said do not use different fluorochromes for compensation and samples.

@@feitu6403 so while I have seen this done, I would highly recommend not doing this. Even if the peak is detected in the same channel, the spillover into different channels will be different, leading to potential compensation errors. Best practice is to always use the same fluorochrome to compensate as you have in your panel. If you do not want to use your cells to do this compensation, you can buy beads at bind the fixable viability dyes.

Hi, first of all, thank you so much for this amazing, easy-to-understand, and very informative video. In your video, after gating for whole and single cells, you've then gated based on FSC-H vs Alexa Fluor (the conjugate), i was wondering the reason for using this paeticular strategy as I previously gated using SSC-A vs the conjugate. What is the difference between the two?

Hi Aja! Super clear and informative video thank you. I have a question... after applying the gates to all of your samples/groups, what if when you scroll through and notice that the gate needs to be adjusted and needs to be re-applied? I am having trouble doing this. After I fix the placement of my gate I wish to apply it to my samples again and its not allownig.. or is this not possible? thank you!!

👍👍👍I have viewed this series several times WHEN I encounter some questions. I am now using Cytek full spectral flow cytemeter. Due to the high sensitivity of the machine, I need to be more careful on antibody titration. There is a question, that may be easy, but confused me a while. For instance, I titrate PerCP or other dyes, I also include live dead antibody, like Live/Dead Blue (a fix dilution, 1:1000), to exclude the dead cells to avoid autofluorescence. Here is the point, although PerCP is easy to be separated from live/dead due to the lower similarity index.Because I saw your titration vedio didn't include live/dead for each antibody titration. Just use size gating strategy to have live cells. I want to hear from you about this. Thanks in advance.

Great to hear from you! I kept my titration video as simple as possible and didn’t have a viability stain in it so there wasn’t the added complication of compensation. However, best practice is to include it, as you have done, so you can eliminate dead cells and thereby choose the correct concentration. On the Aurora, you have a couple of options: 1. You can make single colour controls and unmix before doing your analysis. In this case, you’d need a different experiment for each colour you’re titrating so each has their own matched unmixing matrix. Or 2. So long as you stains are different enough (very different peak channels and distinct aspects) you can do your analysis on the raw data and avoid single colour controls and unmixing. Good luck and happy titrating!!

Hi Aja! Thank you so much for your FlowJo tutorials! I only discovered them today and already watched 3 episodes :-). I have a question, when we drag and drop our samples in FlowJo (or import them), the original names change to a number, which makes it quite difficult to know what sample belongs to what experimental condition. So far, we could not find a way to rename our samples in FlowJo. Do you have any idea/suggestion? Thanks a lot!
@ajarieger_flow
@ajarieger_flow Жыл бұрын
Thanks!! If there’s any topics you’d like covered, please let me know! What you’re seeing is usually a by-product of how the data was exported. When the names change to numbers this indicates that you exported the data out as the “experiment” FCS files as opposed to just the straight FCS files (there are 2 options in Diva- export FCS and export experiment; though both are FCS files, the export FCS ones are meant to be read everywhere while the experiment ones are meant to be read by Diva). I would recommend re-exporting as the export FCS version and your problem will be solved!

Thanks for tuning in! This usually happens when you have plots from more than 1 sample in the layout you want to batch from. If you go back and swap out plots so they’re all from the same sample you should be all set!
