Morphology of sodium deoxycholate-solubilized apolipoprotein B-100 using negative stain and vitreous ice electron microscopy

Overview of electron crystallography of membrane proteins: crystallization and screening strategies using negative stain electron microscopy.

Electron cryomicroscopy, or cryoEM, is an emerging technique for studying the three-dimensional structures of proteins and large macromolecular machines. Electron crystallography is a branch of cryoEM in which structures of proteins can be studied at resolutions that rival those achieved by X-ray crystallography. Electron crystallography employs two-dimensional crystals of a membrane protein em...

The structure of dynein-c by negative stain electron microscopy.

Dynein ATPases contain six concatenated AAA modules within the motor region of their heavy chains. Additional regions of sequence are required to form a functional ATPase, which a previous study suggested forms seven or eight subdomains arranged in either a ring or hollow sphere. A more recent homology model of the six AAA modules suggests that these form a ring. Therefore both the number and a...

The bending of sliding microtubules imaged by confocal light microscopy and negative stain electron microscopy.

Individual microtubules can be visualised by confocal microscopy in reflection mode; when associated with a glass surface, they show up as black lines against the bright reflection from the surface. The high contrast imaging allows details of the behaviour of sliding microtubules to be studied easily. Taxol-stabilised microtubules sliding over kinesin-coated surfaces are normally straight, but ...

Apolipoprotein B 100 and 48

Apolipoprotein B is the main structural surface protein found on all beta-lipoproteins (Chylomicrons, VLDLs, IDLs and LDLs). There is a single molecule of apoB on each of those lipoproteins. It is the only apolipoprotein that is not transferablei.e. it is with the particle from its birth till its death. Beta-lipoproteins are the lipoproteins capable of trafficking cholesterol into the artery wa...
