SynapticProteinsattheSynapticJunction
The postsynaptic density (PSD) is a submembranous structure at the postsynaptic membrane mainly at the excitatory synapses. The neurotransmitter receptors are assembled and fixed at the PSD, and several molecules implicated in the synaptic plasticity are also enriched. PSD-95/synapse-associated protein (SAP) 90 is involved in the molecular organization of these components of the PSD and essential for learning and mem......阅读全文

狭义来讲，提取指制备物与细胞固体成分或其它结合成分的分离，由固相转入液相或从细胞内生理状态转入外界特定溶液环境的过程，即分离前期被提取物从破碎的细胞中释放出来的过程。如果被提取物程固相或与固体结合，提取时由固相转入液相，常称为固液萃取；如果被提取物已经呈液相存在，提取时由一液相转入转入另一互不相溶的
