Proteins that interact with AMPARs
Qdots
Getting a Qdot into the cell
- Conjugate Qdot with secondary antibody fab
- Incubate tissue with primary antibodies for AMPAR and PSD95
- Puff Qdots onto cell body, these will bind the primary at AMPAR N-terminus
- When AMPARs internalize the Qdot will be dragged into cell
- Cleave N-terminus of AMPAR to liberate Qdot
- Qdot can then bind the primary ligated to PSD95
Notes
- Molecular Methods
- FLASH technology
- Bredt
- minisog - gfp
- Acidic basic polypeptide recognition sequences
- Talk with nanotech group about various ways to conj. Qdots
- Nichol and England - couple Qdot to AMPAR agonist
- Have simulation be a competitive model where AMPARs are competing during LTP
- Quantitative review on synaptic numbers (Sheng)
PALM STORM
There are two major groups of methods for functional super-resolution microscopy:
1. Deterministic super-resolution: The most commonly used emitters in biological microscopy, fluorophores, show a nonlinear response to excitation, and this nonlinear response can be exploited to enhance resolution. These methods include STED, GSD, RESOLFT and SSIM.
2. Stochastical super-resolution PALM STORM: The chemical complexity of many molecular light sources gives them a complex temporal behaviour, which can be used to make several close-by fluorophores emit light at separate times and thereby become resolvable in time. These methods include SOFI and all single-molecule localization methods (SMLM) such as SPDM, SPDMphymod, PALM, FPALM, STORM and dSTORM.
