Microparticles and flow cytometry

Postby Jemi » Tue Feb 21, 2012 3:30 pm

Hi,

I've been given several flow cytometry profiles to analyse for a piece of work and I'm slightly confused about one of them.

So far I've worked out that it shows microparticles (I think!) and I know that more side scatter means a more complex cell and that Annexin binds to phosphatidylserine but I'm not sure how to interpret it any further than that. I've been told it comes from someone with a disease (which I have to work out) so I thought maybe I could compare it to the same FC profile for a healthy person but I haven't been able to find one.

Any pointers would be hugely appreciated! Thanks!

I have a question regarding flow cytometry too!!! Please heeelp. I have a lot of questions based on the cytometry pictures, where they ask to calculate percentage of dead cells, or of CD45R etc. Does anyone know how to guide me through the correct answer???

You should probably know how they distinguish them. Don't they tell?

Cis or trans? That's what matters.

I know in which part of the graph the cells are but I am not sure how to calculate the percentage because I understood that we have to subtract the autoflourescence ones from other graph.. something like that. It is very confusing!!

Why could be the reason of finding more B cells in the splean in comparison with T cells???
