EGTA Buffer 0.5M, pH 8.0, DNase and RNase Free
Size : 50mL
Marke : BioWorld
EGTA [Ethyleneglycol bis (2-Aminoethyl ether)-N,N,N',N' tetraacetic acid] is of Molecular Biology grade, and is suitable for all molecular biology applications. Nuclease and protease free, EGTA is used to chelate CA2+ ions in the presence of Mg2+. EGTA chelates these two ions at a 1:1 ratio. EGTA is also used as a calibration standard for calcium ion concentration, with detection accurate to 10 ï¿½M. It can also be used as an anticoagulant at a concentration of 1 g per 100 mL of blood.
EGTA is soluble in 1M NaOH (110 mg/mL). As a saturated solution at room temperature, EGTA concentration is found to be 2 mM at a pH of 2.72.
