Publikacja -
Versatile method employing basic techniques of genetic engineering to study the ability of low molecular weight compounds to bind covalently with DNA in cell free systems.
PublikacjaMechanizm działania większości leków przeciwnowotworowych oraz związków rakotwórczych polega na ich kowalencyjnym wiązaniu z DNA. Poziom tego wiązania jest zazwyczaj bardzo niski, co powoduje, że potrzebne są niezwykle czułe metody aby kowalencyjna modyfikacja mogła być w ogóle wykryta. My podjęliśmy próbę zastosowania w tym celu prostych, szybkich i sprawdzonych technik inżynierii genetycznej: metody PCR do uzyskania fragmentu...
