In this report, we show that an ecto-(Ca, Mg)-apyrase activity is present on EBV-transformed B cells, but not on B or T lymphomas. The coincidence between CD39 expression and ecto-apyrase activity on immune cells suggests that CD39 may be an ecto-apyrase.

Cycloheximide was dissolved in sterile nuclease-free water and used at 20 μg/ml Sigma-Aldrich. Dehydrogenase 0.3 unit per ml, and fructose 1,6-diphosphatase in a final volume of 1.0 ml. Assays were conducted at 30”. Fructose 1,6-diphosphatase was added to the complete system minus substrate, and the reaction was started by addition of FDP. With dialyzed preparations of fructose 1,6-diphos- Finally, we show that CD39 indeed has ecto-apyrase activity by expression in COS-7 cells. This supposition is supported by the observation that the amino acid sequence of CD39 is significantly homologous to those of several newly identified nucleotide triphosphatases.

The cells were washed with PBS and then incubated in OPTI-MEM Invitrogen medium with or without various concentrations of either chloroquine or NH 4 Cl both from Sigma. A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen.
