Micron
. 1998 Dec;
29(5):359-96.
PMID: 9842722
Vertical replication for TEM is ideal for studying non-periodic specimens from 0.7 to 3 nm, a resolution mid-range difficult to attain by any other technique. This paper discusses the importance...

DNA bound to polypyrrole films: high-resolution imaging, DNA binding kinetics and internal migration
Pande R, Ruben G, Lim J, Tripathy S, Marx K
Biomaterials
. 1998 Dec;
19(18):1657-67.
PMID: 9840001
We have studied the time-dependent uptake of 35S radiolabeled DNA with electrochemically prepared polypyrrole films. The two distinct polypyrrole film surfaces, a rough (solution polymeric growth face, R) and a...

. 1998 Jul;
17(1):89-97.
PMID: 9667526
The amount of non-cell-associated DNA free in blood plasma from pancreatic cancer patients usually exceeds that from healthy donors. We have evaluated the plasma DNA by gel electrophoresis and measured...

Synapse
. 1997 Nov;
27(3):208-29.
PMID: 9329157
The chemical interaction that condenses the hyperphosphorylated protein tau in Alzheimer's disease (AD P-tau) into neurofibrillary tangles and cripples synaptic transmission remains unknown. Only beta-sheet, positive ion salt bridges between...

PMID: 9140942
We tested whether the Steitz et al. [(1974) Proc. Natl. Acad. Sci. U.S.A., 71:593-597] model of lactose repressor (LacR) (14 x 6.0 x 4.5 nm) represented the shape of free...

. 1995 Nov;
32(4):312-29.
PMID: 8573781
The real size of platinum-carbon (Pt-C) replicated particles is not directly equivalent to either its metal-coated diameter or its shadow width. This paper describes two indirect methods, shadow widths and...

Brain Res
. 1995 Mar;
675(1-2):1-12.
PMID: 7796117
Untreated paired helical filaments (PHF) and pronase treated PHF filaments have been stereoscopically imaged with a freeze-drying vertical platinum-carbon replication preparation method for TEM. The untreated PHF have an average...

Microsc Res Tech
. 1994 May;
28(1):13-28.
PMID: 8061354
High angle platinum/carbon (Pt/C) replication has proved to be a valuable tool in analyzing basement membrane structure in human amnion, bovine lens capsule, and the Engelbreth-Holm-Swarm (EHS) tumor. High resolution...
