Detection of Human TGF-beta 1 by Flow Cytometry

CD4+ V delta 1+ T-cell clones have a TH0-cytokine profile and are effector-memory cells. (A) CD4+ V delta 1+ clones produce regulatory IL-10 and TGF-beta, TH2 cytokines IL-4, -5, and -13, and to a lesser extent proinflammatory IL-17A and IL-6, and the TH1-cytokines IL-2, IFN-gamma, and TNF-alpha after stimulation with PMA/ionomycin. (B) CD4+ V delta 1+ clones were not naïve but belonged to the effector memory; they were CD45RA−, CD27−, CCR7−, and predominantly CD62L− and CD28±.

    I performed a competition ELISA to see if another company's TGFb1 had a similar epitope to two of R&amp;D's antibodies. I coated my plate with 50ng/well of recombinant mouse TGF beta 1 protein (cat# 7666-MB) overnight. I washed and blocked with reagent diluent 2 DY995 for 2hr, washed and added another company's TGFb1 antibody at different concentrations 0.2-100ug/mL in reagent diluent 2 and incubated 1hr. I did not wash my wells but add the two antibodies MAB240-biotinylated it in-house and BAF at a final concentration of 2ug/mL and incubated 1hr diluted in reagent diluent 2. I washed and added streptavidin-HRP DY998 (1:200) and incubated 30 mins, washed and developed with the substrate pack DY999. I found MAB240 competed for binding to the mouse TGF beta 1 protein when the competitor's antibody was present but the chicken polyclonal was not inhibited.
