Changing staining volume for flow cytometry
I'm building a 32 colour panel that is an extension of an existing 27 colour panel that has already been optimised. However I'm going to need to use Fc Block which wasn't needed on the original 27 colour panel.
In the past I've put on Fc block for 10 mins then added antibody mix directly onto cells from that. My concern in this case is that the final staining volume is going to be higher than in the original panel. I'd quite like to avoid having to re-titrate the other 27 antibodies so wondered what people's experience is changing that staining volume e.g. from 50 to 75uL for the same amount of antibody?
Maybe I just need to test it and see...
Thanks!
