nice video, I am assuming that you have to get the distance in pixels and known distance from your microscope that you used to take the pictures right?
I added the scale bar to the image and now when I save it, it doesn't show the bar, I did several times but didn't, can anybody tell me what to do? I'm new on imageJ I don't know much about
Help me pls. How can I measure a timelap? Like 60 pictures in one file and i want to measure the process of changing intensity. I can only measure one at a time but cant let it measure 60 times each for a picture automatically
Is this method correct tho? The programm calculates the mean intensity of the area you circle in. Imagine you make a big circle around your cell, the mean will be lower because most of the area is just black. If you now substract the mean intensity of the same circle in a empty area, your intensity will decrease even more And When you do a smaller circle just slightly bigger than the cell, the mean will be higher and if you substract the backround of this circle it will not substract that much because the backround is not even big. So the mean intensity will only be determined by how big you set the circle you want to measure and that is not comparable at all
Awesome video!! This really helped
This is really helpful video to know immunofluorescence quantification!

Veeery helpful thank you
you saved my life friend
Thanks for your vdo
thank you so much.
I have pics for MCF 7 cells in vitro stained by Phalloidin 488, how I can analyze them please? 😢
pleasse send for me the file, where can i find it!!???

using macro in image J
Please complete the statistics.
how to measure DAB intensity ?

And

So the mean intensity will only be determined by how big you set the circle you want to measure and that is not comparable at all
you can use the threshold and then do analysis particle to choose the positive area only
想问一下能用imagej计算荧光衰减速率吗？该怎么做
这个你得另请高明了
