Cell lysates prepared from mouse spleen (lane 1), thymocytes (lane 2), or bone marrow (lane 3) were resolved by SDS-PAGE prior to transfer onto a PVDF membrane. The membrane was probed with 2 µg/ml purified 24DMS1 antibody and bands were detected using an HRP-conjugated anti-rat IgG antibody.

Note: The 24DMS1 antibody works only with non-reduced protein without boiling prior to gel loading.

Description

The 24DMS1 monoclonal antibody reacts with mouse CD39, also known as NTPDaseI. E-NTPDases are enzymes that convert nucleoside tri- and diphosphates (NTDPs) into nucleoside monophosphate (NMP), thereby removing toxic extracellular ATP and ADP. CD39 is the dominant member of this family in the immune system and is involved in suppression of inflammation and control of platelet activation. CD39 can impact expression of CD73, another E-NTPase. Together, these molecules influence inflammation responses. CD39 is expressed on B cells, Langerhans cells and most monocytes. In addition, CD39 is found on a subset of CD4+ T cells that are mostly CD25+FoxP3+ T reg cells. T reg cells from CD39-null mice showed impaired suppressive properties in vitro and in vivo.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This 24DMS1 antibody has been reported for use in flow cytometric analysis, and immunoblotting (WB).

Applications Tested

This 24DMS1 antibody has been tested by flow cytometric analysis of mouse splenocytes and by WB. This can be used at less than or equal to 0.06 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
