Provider: Invitrogen Antibodies
Product name: CD73 Monoclonal Antibody (AD2), FITC, eBioscience™
Antibody type: Monoclonal
Antigen: Other
Description: Description: This AD2 monoclonal antibody reacts with human CD73, a 5'-ectonucleotidase that converts 5'-adenosine monophosphate to adenosine. CD73 is expressed on the surface of endothelial cells, as well as B and T cells, including some CD4+Foxp3+ regulatory T cells. Adenosine production by these cells has been linked to the inhibition of CD4 T cell effector functions such as proliferation and cytokine secretion. Applications Reported: This AD2 antibody has been reported for use in flow cytometric analysis. Applications Tested: This AD2 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.
Reactivity: Human
Host: Mouse
Conjugate: Green dye
Isotype: IgG
Antibody clone number: AD2
Vial size: 100 Tests
Concentration: 5 µL/Test
Storage: 4° C, store in dark, DO NOT FREEZE!

Experimental details: Figure 2 Characterization of GMSCs. (A) Flow cytometry analysis indicated that human GMSCs expressed CD73, CD105 and CD90, but not CD45. (B) Expression of stem cell markers in GMSCs. Cells cultured in a 24-well plate were fixed and stained with specific antibodies against human vimentin, CD90, CD73 and cytokeratin (CK). The cells were incubated with rhodamine- or fluorescein isothiocyanate-conjugated secondary antibodies and then observed under a fluorescence microscope (magnification, x200). (C) Immunofluorescence staining revealed that the cytoplasm of CD90- and vimentin-stained cells exhibited red fluorescence, and the cytoplasm of S100A4-stained cells exhibited green fluorescence. The nuclei of all cells exhibited blue fluorescence, whereas the cytokeratin-stained cells exhibited no fluorescence (magnification, x200). GMSCs, gingiva-derived mesenchymal stem cells.

Experimental details: Figure 1 Identification of BMSCs in mice. Morphological observations at different magnifications (40x, 100x, and 200x) showed that the bone marrow stem cells (BMSCs) isolated from mice were homogeneously elongated ( A ). Various cell surface markers of BMSCs were detected on the cells, including CD90, CD73, CD105, CD44, and CD45 ( B ). The values are from triplicate determinations. A P value less than 0.05 was considered to be statistically significant. ***Indicates a P value less than 0.001.

Experimental details: Figure 2 Flow cytometry of CD cell surface markers for cells cultured under hypoxia and normoxia. The positive CD markers for MSCs as detected by the fluorescent antibodies anti-CD73 FITC, anti-CD105 PE, and anti-CD90 PE Cy7. The negative markers of MSCs were detected using anti-CD14 FITC, anti-CD45 PerCP, anti-CD34-R-PE, and anti-CD19 PE-Cy7 antibodies. Unstained cell for each condition was used as negative controls.
