2826495-1	1987	Small bipolar filaments, or "minifilaments," are formed when smooth muscle myosin is dialyzed against low ionic strength pyrophosphate or citrate/Tris buffers.	Citric Acid	138-145	myosin heavy chain 14	Homo sapiens	75-81	
3681974-1	1987	Electron microscopic observations of negatively stained myosin minifilaments in a solution containing 10 mM-citrate buffer (pH 8.0), 4 mM-MgCl2 reveal ordered assemblies.	Citric Acid	107-115	myosin heavy chain 14	Homo sapiens	56-62	
3485450-2	1986	Nevertheless, the presence of nonequivalent bonding interactions within the filament permits differential stabilization of several macromolecular assemblies of myosin under well-controlled ionic conditions in citrate/Tris buffer at pH 8.0.	Citric Acid	209-216	myosin heavy chain 14	Homo sapiens	160-166
