Communications in nonlinear science & numerical simulation

Magin RL, Akpa BS, Neuberger T, Webb AG.
PMID: 21804746
Commun Nonlinear Sci Numer Simul. 2011 Dec 01;16(12):4581-4587. doi: 10.1016/j.cnsns.2011.04.002.

We report the appearance of anomalous water diffusion in hydrophilic Sephadex gels observed using pulse field gradient (PFG) nuclear magnetic resonance (NMR). The NMR diffusion data was collected using a Varian 14.1 Tesla imaging system with a home-built RF...

PMID: 24302208
Planta. 1981 May;151(6):549-54. doi: 10.1007/BF00387434.

Malic enzyme (ME=L-malate: NADP oxidoreductase; E.C. 1.1.1.40) was extracted by Triton X-100-induced resolubilization of enzyme proteins which denaturize spontaneously upon homogenization of grape berry material. The purification procedure included fractionating with (NH4)2SO4, preparative IEF, and Sephadex G-100 chromatography. ME...

Purification and characterization of barley-aleurone xylanase.

PMID: 24232655
Planta. 1986 Nov;169(3):415-9. doi: 10.1007/BF00392139.

Xylanase (β-1,4-D-xylan xylanohydrolase; EC 3.2.1.8) from aleurone layers of barley (Hordeum vulgare L. cv. Himalaya) was purified and characterized. Purification was by preparative isoelectric focusing and a Sephadex G-200 column. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the enzyme showed...

An in vitro association of soluble phytochrome with a partially purified organelle fraction from barley leaves.

Planta

Smith H, Evans A, Hilton JR.
PMID: 24414635
Planta. 1978 Jan;141(1):71-6. doi: 10.1007/BF00387747.

Red light treatment in vitro increases the pelletability of phytochrome in homogenates of etiolated barley (Hordeum vulgare L. cv. 'Julia') leaves. When mixtures of soluble phytochrome (100,000 x g supernatant) and partially-purified organelles (Sephadex G-50 eluate) are irradiated the...
