Metabolic syndrome is a clustering of various conditions including high blood pressure, high blood sugar, excess body fat, high serum triglycerides, and low high-density lipoproteins. Scientists studying metabolic syndrome cultured fibroblast cells from a metabolic syndrome patient and a healthy volunteer and challenged the cells to 100 nM insulin. Ten minutes after the stimulus was applied, they used a protein Immunoblot to measure the amount of phosphorylated insulin receptor in the cultures.
