Caバッファー濃度計算プログラム

CALCON



In order to mimic intracellular cation (e.g. Ca2+) concentrations, we usually include
cation chelators such as EDTA and EGTA in our buffering solution. However, as normal cells
also contains ATP that also binds to Mg2+ and Ca2+, we are required to solve complicated
sysyetm of equations in order to estimate actual concentratins of free cations and MgATP etc.
Please, use this progrtam in such a case.

細胞内のCa濃度は,1μM〜0.1μMと極めて低い濃度であるが,in vitroでこの
条件を達成するにためにはEGTAやEDTAなどの2価イオンキレーターを使用する.
ここで紹介するプログラムは,通常in vitro用緩衝液に,これらのキレーターやMg,Ca
などの2価の金属の塩を用いたときの濃度の計算を行うプログラムである.
