Company:

BioLegend

Product Name:

PE anti-mouse/rat/human Foxp3 antibody

Catalog Number:

320008

The general aim was to determine how T cells are differentiated following different stimulation conditions. This product was purchased because BioLegend is a company that I trust.

Results Summary

For this experiment, I fixed and perm my cells. For compensation, I used eBioscience's beads. This antibody was a poor antibody to detect Foxp3. When I was acquiring my experimental sample, most of the events was not showing within the dot plot and had to recompensate and alter the PMT voltage. A few scattered events were displaying in the Foxp3 positive gate, however I question the validity of the results.

Additional Notes

None

Summary

The Good

Can be optimized

The Bad

Bad fluorochrome

The Bottom Line

I would choose a different fluorochrome that is not PE.
