12411747-5	2003	A 100-kD protein reactive with antibody against muscle alpha-actinin was purified from the Triton-insoluble cytoskeleton of porcine kidney, by MgCl2 treatment, ammonium sulfate fractionation, and subsequent DEAE-cellulose chromatography and hydroxyapatite chromatography.	Magnesium Chloride	143-148	actinin alpha 1	Homo sapiens	55-68	
2241989-1	1990	At 37 degrees C, in the presence of 0.1 M KC1 and 2 mM MgCl2, the binding of alpha-actinin to F-actin increases with the concentration of alpha-actinin but not with the concentration of F-actin.	Magnesium Chloride	55-60	actinin alpha 1	Homo sapiens	77-90
