I just discover this série. I really like how clear and concise is the video on one flowjo function. And indicating the other videos on more on the topic

Please could you provide a video in how to calculate the stain index? This video was fantastic, as I literally did a Ab titration last week.

Awesome video! it really explains an easy way to understand how across titrations the different variations of fluorcrome intensity compared to the NS. Could you post a video using the FlowJo Stainindex plug in? I really want it to work and dont know how it really works. Very best

Awesome! I'm new in flow cytometry, lots of things to learn. As you said, like the CD11c, we can not see the break in flowjo, have to calculate the SI to find the best concentration to use, could you please tell me how to calculate the SI and make the curve to see which concentration that I can use? Thank you so much.

Thanks for tuning in! We just posted a video yesterday on stain index- you can check it out here: kzfaq.info/get/bejne/iJNymdJ21KqyiIU.html

I am working on a follow-up video to show stain index calculation with more challenging populations.

Can you present ab titration protocol : do you start with the manufacturer concentration titer ?and how many dilutions you do and what is the parameter you use (signal/ noise) to chose the optimal ab concentrations.Thank you

That would be a great video- I will add it to my list :)

Very useful video! Thanks! I have a question: When I selected Sample ID, nearly all my events were on the chart edges. I had to change into log axis in order to see the events, but the resolution is bad. Is it because how I acquired my samples? Thanks in advance!

@ajarieger_flow Жыл бұрын

Thanks! Without seeing the data, it is hard to tell… feel free to send me an email @aja@ualberta.ca and I can take a quick look

At 2:53, you mentioned that "this particular marker has a high background", how do you mean by that? How do you see the "background"??

@ajarieger_flow 4 ай бұрын

High background refers to the spread in the signal in the unstained sample. The last sample on the plot is unstained and you can see how far the signal spreads up the y axis.

I made a mistake in naming my samples while running flow cytometry. I have already analyzed the data using Flow Jo, and are in wsp format. Is there any way to rename the sample names in analyzed data in Flow jo?

@ajarieger_flow Жыл бұрын

The filename from acquisition is hard-written into the FCS file and can't be changed in FlowJo. Your best bet is to use keywords to rename and go based off that. OR you can go back into your acquisition file and rename there and export again. Hope that helps!

@chris-jh4cx 2 жыл бұрын

Should you not include a live/Dead with your dilutions, as dead cells stain everything?

@ajarieger_flow 2 жыл бұрын

Hi @chris, I don't normally but I do try run my titrations on populations that I know will have good viability. Then I don't need to worry about compensation. For stain index calculations, I recommend taking a look at this : fluorofinder.com/newsletter-staining-index/

At 2:44 and 3:59 to show concat titration plot, how do you which plot for which titration?

@ajarieger_flow 2 жыл бұрын

They will be ordered based on the order in which you selected them. You could also give each file a keyword (numerical keyword is recommended) to make it easier in the future

For sure! So I am on the same page- are you looking for a video that shows how to get statistics like gate % and MFI from FlowJo?
