Silver carp serum immunoglobulin was purified using immunoaffinity chromatographic column, and the serum IgM with high purity was then obtained. The IgM H chain and L chain were estimated to be about 76.4 kD and 27.2 kD, respectively. Simultaneously, mannan-binding protein (MBP) affinity chromatogra...

The effects of water deficit on photochemical parameters and activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD) were investigated in two cultivars of rice. The soil water content fell to about 40% of field water capacity after withholding irrigation for 14 d. As a result, the...
