Sorry.  You're not the only one who asked.  SEB is Staphylococcal 
enterotoxin B.  It is a superantigen for T-lymphocytes.

Sorry to ask a dumb question but what is SEB?

I had the same problem.  PHA by definition is a hemagglutinin.  I started
stimulating with SEB instead.

Dear colleagues,

I am looking at intracellular cytokines produced by CD14+/CD3+ cells from
PBMC cultures, in response to PHA stimulation. I am having problems with
cell aggregation . Has anyone used a similar system and how did they get
round it? Stimulating with PMA/ionophore is not an option at the present

Thank you in advance,

Tom Rowland
