We are assessing consequences of Aryl hydrocarbon Receptor (AhR) activation in dendritic cells. Specifically for these experiments we were assessing Aryl hydrocarbon Receptor activation in bone marrow derived dendritic cells. Precursor cells are isolated with Lympholyte M from whole bone marrow suspensions and grown in the presence of GM-CSF for 5-7 days. We then use flow cytometry and RT-PCR to assess changes in dendritic cells after AhR activation. Here, we are assessing the expression of PD-L1 (CD274) on bone marrow derived dendritic cells.

Results Summary

This antibody gave us a shoulder population for PD-L1. It was difficult to get separation of positive and negative peaks; however, other cell types may give different results.
