Detection of Platinum Species in Plant Material by Preparative Isotachophoresis Using the Model 491 Prep Cell, Rev A

...is, there is an efficient counteraction of diffusion as a consequence of a zone sharpening phenomenon. Sample zones maintain sharp boundaries resulting in high resolution and highly concentrated zones. In order to resolve the isotachophoretically-separated zones it is nece...

The Bio-Rad Silver Stain, Rev E

...ed, the proteins must be fixed to minimize diffusion of molecules in the gel. Fixation also elutes substances from the gel that are likely to interfere with establishment of the oxidation/reduction potential differences and with silver reduction. Ampholytes, detergents, reducing...

Monitoring Bacterial Genetic Diversity in a Freshwater Lake Using TTGE and DNA Sequence Analysis

... with a sterile scalpel, eluted by passive diffusion into 1.25x TAE and sequenced. Results and Discussion TTGE analysis of freshwater Nitrosospira 16S rDNA PCR products revealed both genotypic continuity and variation between individual samples (Figure 1). Co-...

UW-Madison puts heart and mind into stem cells

...n is to insert GDNF directly in the brain, but the diffusion of the chemical is limited and costs about $2,000 a day. Svendsen said that getting the neural stem cells into the brain can help the levels of dopamine rise by naturally encouraging the existing cells to produce more GDNF. More importantly, in enco...
