Agar 86-90 alpha fetoprotein Homo sapiens 0-17 4141942-2 1974 The presence of AFP was detected in 9 sera by agar-gel precipitation and in 22 additional sera by the more sensitive aggregate haemagglutination technique. Agar 46-50 alpha fetoprotein Homo sapiens 16-19 4329951-1 1971 Human alpha fetoprotein (AFP) has been detected by the agar double diffusion method in ascitic fluid, cerebrospinal fluid (CSF) and bile, from fetuses, neonates and patients with AFP seropositive hepatocellular carcinoma. Agar 55-59 alpha fetoprotein Homo sapiens 6-29 48562-4 1975 Only one patient had a level exceeding 3,000 ng/ml, the concentration at which alpha-fetoprotein is detectable by agar-gel diffusion.
