Electrophoresis

De Cock B, Van Eeckhaut A, Stiens J, Mangelings D, Vander Heyden Y.
PMID: 26202748
Electrophoresis. 2015 Nov;36(21):2658-2664. doi: 10.1002/elps.201500273. Epub 2015 Sep 07.

The increased interest in the separation of peptides, proteins, immunoglobulins, and polynucleotides, led to an increased demand for appropriate analytical methodologies and instrumentation. CE, because of its unique separation mechanism and high efficiency, is frequently used in the analysis...

In just over a decade since its discovery, research on graphene has exploded due to a number of potential applications in electronics, materials, and medicine. In its water-soluble form of graphene oxide, the material has shown promise as a...

A simple and general plant tissue extraction procedure for two-dimensional gel electrophoresis.

Plant cell reports

Mayer JE, Hahne G, Palme K, Schell J.
PMID: 24248456
Plant Cell Rep. 1987 Feb;6(1):77-81. doi: 10.1007/BF00269745.

A fast and simple extraction procedure of plant tissue for two-dimensional gel electrophoresis is presented. The procedure is especially useful for the extraction of plant cell suspension cultures, callus and other plant tissues having a high content of phenol...

ESR of Cu(2+) bound to polynucleotides and derivatives.

FEBS letters

Bemski G, Rieber M, Wust M.
PMID: 11945734
FEBS Lett. 1971 Apr;14(2):117-120. doi: 10.1016/0014-5793(71)80115-1.

Binding of Cu(2+) to polynucleotides has been found to occur at 1 Cu/5 polymer P and at similar molar ratios of copper to selected nucleic acid derivatives. Electron spin resonance (ESR) measurements show that the g-values and the hyperfine...

Unique Catalysis and Regioselectivity Observed in the Poly(C)-Directed RNA Dimer Formation from 2-MeImpG: Kinetic Analysis as a Function of Monomer and Polymer Concentration.

The Journal of organic chemistry

Kanavarioti A, Baird EE, Hurley TB, Carruthers JA, Gangopadhyay S.
PMID: 11674755
J Org Chem. 1999 Oct 29;64(22):8323-8333. doi: 10.1021/jo991216q.

Polycytidylate, poly(C), serves as a scaffold or template to direct and catalyze the synthesis of long oligoguanylates from guanosine 5'-phosphate 2-methylimidazolide, 2-MeImpG. In the absence of poly(C), small amounts of three isomeric dimers, i.e., the 2'-5'-, the 3'-5'-, and...

A time-resolved fluorescence study of 4',6'-diamidine-2-phenylindole dihydrochloride binding to polynucleotides.

Biophysical chemistry

Cavatorta P, Masotti L, Szabo AG.
PMID: 17007778
Biophys Chem. 1985 Jun;22(1):11-6. doi: 10.1016/0301-4622(85)80021-1.

At phosphate/dye (P/D) ratios greater than 30 the quantum yield of 4',6'-diamidine-2-phenylindole dihydrochloride (DAPI)-DNA and DAPI-poly(d(A-T)) complexes was found to be 0.62 and 0.66, respectively. Contrary to earlier reports a fluorescence enhancement of DAPI-poly(d(G-C)) complexes was observed with a...

Nucleic Acid Polymerases: Possible Subunit Structure.

Science (New York, N.Y.)

Lee-Huang S, Cavalieri LF.
PMID: 17738156
Science. 1965 Jun 11;148(3676):1474-6. doi: 10.1126/science.148.3676.1474.

A hybrid polymerase which catalyzes the synthesis only of helical polynucleotides with one DNA-like strand and one RNA-like strand can be altered by certain treatments so that it will then synthesize DNA and RNA. There is evidence that the...
