- 10:05Conclusion
Xenopus æggeekstrakt er et nyttigt model-system til at undersøge DNA beskadigelse checkpoint'et. Denne protokol er til fremstilling af Xenopus æg ekstrakter og DNA beskadigelse checkpoint'et inducerende reagenser. Disse teknikker kan tilpasses til en række DNA-ødelæggende fremgangsmåder i undersøgelsen af DNA beskadigelse checkpoint'et signalering.
