AMES TEST SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
Ames testi
Ames testi, verilen bir kimyasalın kansere neden olup olamayacağını test etmek için bakterileri kullanan yaygın bir şekilde kullanılan yöntemdir. Daha resmen, kimyasal bileşiklerin mutajenik potansiyelini değerlendirmek biyolojik bir testtir. Pozitif bir test, kimyasal maddenin mutajenik olduğunu ve dolayısıyla bir kanserojen olarak rol oynayabileceğini gösterir; çünkü kanser sıklıkla mutasyona bağlıdır. Test, bir bileşiğin kanserojen potansiyelini tahmin etmede hızlı ve kullanışlı bir testtir; çünkü farelerde ve farelerde standart kanserojen testleri zaman alıcı ve pahalıdır. Bununla birlikte, sahte-pozitif ve yanlış-negatifler bilinmektedir. Prosedür 1970'lerin başında Bruce Ames ve Kaliforniya Üniversitesi Berkeley'deki grubunun bir dizi makalesinde tanımlandı.
