A Size exclusion Chromatographic analysis was carried out to study the co-elution pattern as well as the molecular interaction between neurotoxic Amyloid beta oligomers and human blood plasma proteins. Four different types of Chromatographic columns like Sephacryl S-100 HR, Superose 12HR 10/30, Superdex 75 HR 10/300 and Superdex 200 HR10/300 used for analysis and among these columns, Superdex 200 HR 10/300 shown to be the most convenient column with better resolution where 20 mM sodium phosphate, pH 7.4; 150 mM sodium chloride proved as best working buffer at 0.5 ml/min flow rate. Co-elution study of mixture of amyloid β oligomers and human plasma serum showed weak molecular interactions with blood plasma proteins but no strong interaction could be observed.
