A, B ve AB grubundaki kanlarda ba\u011f\u0131\u015f\u0131kl\u0131k sistemi taraf\u0131ndan tan\u0131nan farkl\u0131 \u015feker molek\u00fclleri bulunurken 0 Rh (-) grubundaki kanda bu molek\u00fcllerin olmad\u0131\u011f\u0131 tespit edilmi\u015fti. Bu minik \u015feker molek\u00fcllerinin olmamas\u0131 sayesinde 0 grubu t\u00fcm gruplara kan verebiliyordu.<\/p>\n
Ara\u015ft\u0131rman\u0131n 1980\u2019li y\u0131llar\u0131n ba\u015f\u0131ndan beri devam etti\u011fi bildirildi. Ara\u015ft\u0131rma ile minik \u015feker molek\u00fcllerinin bir \u015fekilde al\u0131nmas\u0131 ya da yok edilmesinin tasarland\u0131\u011f\u0131 belirtildi.<\/p>\n

Yeni ke\u015ffedilen enzim \u00f6nceki bulunan \u00f6rneklerden 30 kat daha h\u0131zl\u0131 ve y\u00fcksek verimle \u015feker molek\u00fcllerini par\u00e7alad\u0131\u011f\u0131 belirtildi.
