- Description
- Description: The eBioA1 monoclonal antibody reacts with human CD39 also known as ectonucleoside triphosphate diphosphohydrolase 1 (ENTPD1) or NTPDase. CD39 is an integral membrane protein with two transmembrane domains and exists as a homotetramer. It is the most prominent ectoenzyme of the immune system. The function of CD39 is to effectively remove toxic extracellular ATP by converting it to ADP or AMP. CD39 is thought to work together with CD73 to hydrolyze ATP and has been well characterized on Langerhans cells. Expression of CD39 was originally identified on activated lymphocytes. Expression is also found on a subset of T cells, B cells and dendritic cells as well as weak staining on monocytes and granulocytes. Recently, CD39 and CD73 have been found on regulatory T cells (Treg). Expression of CD39 on Treg may facilitate their entry into inflamed areas where high levels of ATP are present. Expression of CD39 on Foxp3+CD4+ cells ranges from 25-45%. Applications Reported: This eBioA1 (A1) antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBioA1 (A1) antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.25 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 488 nm; Emission: 520 nm; Laser: Blue Laser. Filtration: 0.2 µm post-manufacturing filtered.

- Figure 7 Effects of TEX on protein expression and functions of T cells. In ( a ) down-regulation of CD69 protein expression on the surface of responder CD4 + Tconv after co-incubation with TEX. Activated CD4 + Tconv were co-incubated with TEX (10 ug protein) produced by the PCI-13 cells or with PBS for 12 h. The CD69 expression levels on CD4 + Tconv were then determined by flow cytometry (MFI) and were converted into MESF units based on calibration curves established with fluorescent calibration beads. The bar graphs show data (mean values +- SD) from 3 independent experiments performed with CD4 + Tconv obtained from different normal donors. The asterisks indicate p values at p < 0.0005. In ( b ) changes in expression levels of CD39 protein on the surface of resting CD4 + CD39 + Treg co-incubated with TEX produced by the PCI-13 cell line or DEX. The exosomes were used at the concentration of 10 ng protein/ assay. Exogenous ATP was added as described in Methods. Flow cytometry ( right ) shows up-regulation of MFI for CD39 in a representative experiment, and the bar graph summarizes results of three experiments performed with Treg obtained from different donors. In ( c ), Production levels of 5' AMP, adenosine and inosine by resting CD4 + CD39 + Treg co-incubated with TEX produced by the PCI-13 cell line. The data are from one of two experiments performed in the presence of exogenous ATP. The analyte levels were measured by mass spectrometry as described in Methods.

- Fig. 4 Analysis of tumor-infiltrating lymphocytes. a Proportions of CD8 + and CD4 + T cells from biopsy material, and proportions of these that were positive for PD-1 and CD39. Sample UM22 was derived from a patient that has previously been treated with chemotherapy, possibly affecting TIL proportions in this sample. b Assessment of T-cell reactivity against MART-1, gp100 and NY-ESO-1 in yTIL cultures. Proportions found to be reactive are indicated. Samples tested were those with the HLA-A*02:01 genotype, as this genotype is known to present MART-1 and gp100. Samples with this genotype (Supplementary Data 7 ) that are not shown were also tested and found to be negative. c Analysis of relative levels of PDCD1 (PD-1) and ENTPD1 (CD39) expression among different CD8 + T-cell clonotypes, determined by single-cell RNA-seq of yTILs. Clonotypes with one pair of alpha and beta chain were included, and the ones with greatest expression of both markers are highlighted. Point sizes are proportional to clonotype frequency. Gray color indicates clones that were negative for either PDCD1 or ENTPD1 , whereas other colors indicate different clonotypes that correspond to those in Supplementary Fig. 7e . d Expression of T-cell markers and checkpoint receptors in bulk RNA-seq data from biopsies (batch-corrected log 2 RPKM normalized values). yTILs young TILs, TILs isolated and expanded from a biopsy with a low dose of IL-2.
