At present, the Avian Leukosis Antigen Examination Reagent Kit, a research project of the national “948” strategic research topic, with Professor Chen Fuyong, College of Veterinary Medicine, China Agricultural University, as the principal investigator, had passed the check and acceptance by the national “948” Project Group in the China Agricultural University, and also passed the evaluation of related experts from the Ministry of Agriculture. The experts have unanimous view that this project achievement has filled in the gaps in this field and reached the world advanced level.

Avian leucosis virus is a very common intrinsic leucosis virus. The major host of this virus is chicken, occurrence rate is, in general, 3%~30%. The growth and production of infected chickens are seriously influenced. Due to the vertical contamination of the disease, it causes enormous hazard to poultry industry. However, this disease has insignificant clinical characters, and very easy to mix up with other diseases. In the past, China had used imported reagent kit to examine this disease, with high price of over 5000 RMB per kit; most enterprises could not tolerate such high examination cost.

Through 6 years of efforts in the research team headed by Professor Chen Fuyong, they have made full absorption of the imported technology and its resources, with continuous exploration; they finally developed the Avian Leukosis Antigen Examination Reagent Kit with autonomous intellectual property right. This reagent kit has the characters of simple operation, rapid reaction, high sensitivity, and high stability, with a check out rate similar to the imported kit but the cost has been reduced by a big margin. It is of great importance in the application of this technology in the control and purification of avian leucosis in China, and examination of extrinsic virus of biological products. It is estimated that this research achievement will enter industrialized operation in 2 years and will produced enormous social and economic benefits.
