Your excellent explanation on how Flow Cytometry works helped me a lot today. Thanks!

Very useful and didactic video. Congrats

Amazing..very helpful video.thank you

[@loayk2754]

Thank for the simplicity of explanation

[@AA-gl1dr]

Very clear and understandable. Thank you greatly for your lectures!

[@yousufhaidari6319]

nice bro

[@beneamery814]

So small molecules will give less FW scatter in comparison to large molecules? How does that work? I always thought it was the other way around; big molecules block more light then small molecules so give less FW scatter. Can u explain it to me pls?

[@biomedicalandbiologicalsci4989]

The cells are so small to block the laser beam ... the small cells cause less forward scatter and the large cells cause more scatter (as shown in the video between 2:50 and 3:00) ...

[@ssjgold]

It's less "block more light" and instead scatters the light. So as was said before, all of the cells are too small to block the laser beam entirely. But, instead, as they pass through, they change the angle of the light so that it's not going straight, but scattering it. But think of it like a water tap. If you pass a small thing through it (your finger, for example), the flow breaks and spreads out. But if you pass something much larger (your fist, for example), the same thing happens, but to a much larger area. So, a small cell will scatter/spread out the light as it passes through it, but a bigger cell makes a much larger area of light scatter as it passes through. Hopefully that made sense...

who i can detect the number of WBCs

[@snehadesai4464]

Is it that pc converts light intensity to voltage

[@jannaarmstrong4048]

Very good job at explaining this procedure!

[@mernaelnosiry9672]

Very useful. Thank you ❤️

[@fabricgsome]

Hello, outstanding explanation

[@papinandi4975]

Pls pls upload a video on circular dichromism

[@mohitjesani2797]

you need to revise it properly

[@Ericx2010]

Quick question for my general understanding? At around 03:00 you say that the greater the cell, the more light will fall on the detector and vice versa for smaller cells. My question is; Shouldn't it be the other way round, since the size of the detector won't change and the light will scatter more in other directions, thus leaving a larger 'shadow' behind on the detector? Would appreciate an answer and thus thank you in advance. However, thanks for the effort and the very nice demonstration on how this works! Stay motivated and curious! =)

[@tazarot]

Scattering appears not from the "borders" of the cell as it is in the pictures here, but from different intristic parts of the cell. So, if you have a larger cell, your detector will get scattered signal for longer time, thus the width of the forward signal peak (which is normally refered as FSC-W) wiil be greater than it is for a smaller cell. The height of the forward scattering peak (FSC-H, the maximum amount of light scattered during an event) could not be directly associated with sizes of the cells, but could be a marker which is unique for every type of cells. Normally we want to take in account both parameters (size and "type"), so we use their combination which is an area under the peaks curves (FSC-A).

[@Drmzzzzzzz]

Great explanation, thanks !

[@mayaasrivastava23]

Loved the explanation

[@floflyberlin7392]

so far so good ,but where are the erythrocytes?

[@biomedicalandbiologicalsci4989]

Hei, you can extract leucocytes from a blood sample in the laboratory ..

[@marissafahlberg721]

Usually the red blood cells are lysed and removed before running cells through the flow cytometer. In addition, we often set the threshold of a flow cytometer too high so that RBCs are excluded. If you were to keep the erythrocytes in the sample and set your threshold low enough to see them, they are very small and not granular, so they would show up at the very bottom left corner.

[@Drsamiullahkhan4353]

Great explanation..

[@wheramou]

Very clear and helpful! Thank you!

[@iamsurbhigupta77]

So basically forward scattering depend upon size while side scattering depend on density.

[@marissafahlberg721]

Forward scatter depends on size and side scatter depends on granularity, or cell complexity, but not density.

Such aberrated speech...can't focus at all...myself, being a stammerer, I re-record the broken parts of voice over as many times as required...and that is important!

[@KJKP]

At 4 minutes, does the data go directly to a PC, or is there a logic controller involved?

[@aishasaad6101]

Your oration is very poor. Try to improve

[@nicolasbard4180]

You didn't do the best at explaining, a lot of "uhm"s and "uhhh"s, you were lost for your words half the time. In saying that the graphics is what saved this. I came here for a quick review so I knew what you were trying to say. I'd prepare a script for your next video.

[@chimpalahee]

Very well explained thank!

[@danielhewing64]

umm which i have aaaaa an example of i i i have aaaa an aaaaaa example of red blood cells........

[@Nefglarien]

I think most important is that she explains everything very clearly and it's easy to understand and remember. There is a lot youtubers with better oral skills but their explanations isn't so easy to follow. So I prefer her "aaaaa" that some else's fluency

[@saramalik5440]

You have amazing clarity with concepts but you need to work on delivery part, it gets to the point where it pisses off humongously
