Since you are studying platelet adhesion, do you need red blood cels around.  
YOu could remove them by sedimenting them out and then use the plasma for your 
flow studies.

Subject: Re: Blood is settling

Hi all -

I sent this a while ago and never really found a response that seemed like a
viable option.  Could anyone suggest some other perturbation that may
inhibit red blood cell sedimentation?  I'd prefer to not add any solutes
(unless they are entirely benign) to the blood like others suggested.

Thanks
Josh
