Product Name:

IFN gamma Monoclonal Antibody APC

Catalog Number:

17-7311-82

Clone Number:

Our lab studies the role of mTOR signaling in CD8 T cell differentiation and function. T cell differentiation requires a dynamic change in transcriptional activity leading to effector programming. To assess effector function of CD8 T cells, we measure IFNg cytokine expression through flow cytometry.

Experimental Design and Results Summary

Applications

Flow Cytometry

Sample

Activated murine CD8+ T cells

Primary Incubation

1:1000 in 1x BD Permwash buffer (Intracellular Staining)

Blocking Agent

Surface stain with FC Block before Fix/Perm (BD CytoFix/Perm)

Secondary Incubation

None

Tertiary Incubation

None

Detection

BD FACS Celesta

Results Summary

Upon T cell stimulation, we are easily able to detect CD8+IFNg+ cells using flow cytometry.

Summary

The Good

Very robust and bright antibody at very good dilution makes it cheap in the long run.

The Bad

None.

The Bottom Line

Great antibody to assess effector function of T cells based on IFNg secretion.
