I am in charge of the Plant Cell Biology Core Lab. We have various techniques related to electron microscopy, including ultramicrotomy, negative staining, shadow casting, freeze substitution, freeze etching, immunogold labeling, and etc. In recent, we have set up two new techniques of EM, cryo-SEM and high pressure freezing combined with freeze substitution. The services including : maintaining the equipments and the laboratory for sample preparation, microtomy, and various cryogenic methods.; providing up-to-date knowledge on EM methods for cell biology and immunocytochemistry, in particular the use of cryogenic techniques.;  training new users to make best use of our equipments and various techniques.; assisting users in choosing the right methods and protocols for their research.; and supplying a range of reagents specific for the relevant EM methods and protocols.
