Magnesium Chloride 196-201 actin, beta Gallus gallus 148-153 8055911-11 1994 This Kd was found to be 0.4 microM in the presence of 1 mM MgCl2 and the absence of KCl and, thus, close to the critical concentration of actin polymerization under these conditions. Magnesium Chloride 59-64 actin, beta Gallus gallus 138-143 8395885-3 1993 At pH 7.5 and 37 degrees C, in the presence of 0.1 M KCl and 2 mM MgCl2, the dissociation constant at infinite actin dilution, Ko, is 2.17 microM. Magnesium Chloride 66-71 actin, beta Gallus gallus 111-116
