Label-free and real-time detection of specific binding of IgG proteins by oblique-incidence reflectivity difference method

The entire interaction process between anti-mouse immunoglobulin-G (IgG) and mouse IgG with a concentration range from 1 to 0.25 mg/mL has been label-free detected by the oblique incidence reflectivity difference (OIRD) method.We achieved the two-dimensional scanning images of OIRD Re{△ p △s } intensities before and after interactions as well as the curves of reaction dynamic processes.The experimental results suggest that OIRD method not only can label-free distinguish the different concentrations of proteins and detect biological microarrays,but also can real-time monitor the kinetic processes of biomolecular interactions.

Genetic study on the behavior of honeybees influenced by polyandry system

Within a honeybee population, due to polyandry, there are supersister and halfsister relations, thus many subfamilies exist. For the Chinese honeybee (Apis cerana cerana F.) a phylogenetic dendrogram has been constructed in which 4 subfamilies are clustered based on DNA fingerprint patterns. And it has been observed that each kind of workers is distributed to several dierent sub-families.
