Hi everybody,

I am passing the following message on behalf of a researcher in our HIV
research labs. In our lab we are familiar with the analysis of T cell
subsets, currently using the Coulter tetraCHROME reagent. However this
researcher is interested in cell sorting and how to set up the BD flow
sorter to get the cells of interest. As a consequence I am of no use
whatsoever. The antibodies that we currently have at our disposal are the
Coulter tetraCHROME CD45 FITC/CD4 PE/CD8 ECD/CD3 PC5 and BD CD3/CD8/CD4
together with the BD Tritest control. Analysing the cells are no problem
it's just how th set up the sorter to get the correct cells out!

This is the problem;

Basically what I want to do is as follows
Take 40mls patient blood, ficoll separation.
Stain PBMCs in such a way that I can put them thru a cell sorter and
collect as many cells as possible as need to extract DNA from the
following , to then do a series of PCR reactions to determine integrated
HIV DNA.
Interested in CD4+ lymphocytes (CD3+/CD4+), CD8+ and the small number of
double negative cells (cd4-/CD8-) as these are possibly CD4+ cells that
have down regulated their receptor post HIV infection. I guess the ideal
scenario is to pass the cells thru and collect all CD3+ cells and then
the rest. Then pass thru these CD3+ cells and differentiate between the
4s and the 8s????

Thanks any suggestions welcome !
