Intracellular cAMP contents in MC3T3-E1 cells cultured on surfaces with attached PTH(1-34). Peptide was immobilized via hydrazide spacers, directly on carbodiimide-activated surfaces (Ran), and by simple adsorption (Ads). The amount of cAMP was normalized by DNA content and the mass of PTH(1-34) present on the surfaces.
