finally , when we first blocked bulk lysines on microtubules ( hrl unreactive ) using unlabeled acetaldehyde and then measured the amount of [ 14c ] acetaldehyde adduct formed with tubulin after depolymerization ( hrl reactive ) , 0.08 mol acetaldehyde/mol tubulin resulted in completely impaired polymerization .
