Companies will now think more carefully about the number of options they offer, since it won't be so easy to avoid dilution: Shareholders will ask why they can't get the cash.
It isn't easy to measure genetic "dilution".
We chose for each agent the lowest dilution insuring easy and reproducible pipetting and wells pouring: 1/2, 1/4 and 1/4 w/v for Betadine gel®, SSD and SSDC respectively.
Richard L. Hasen, an election law specialist at Loyola Law School in Los Angeles, noted that views could change over time, but added that Mr. Roberts in 1981-82 "showed a pretty strong disagreement with the efforts to make it easier to prove vote dilution".
While RT dilution seems the easiest way to overcome this inhibition, as has been widely recommended to augment qPCR amplification success [5], [12], [13], [14], this strategy has the negative consequence of reducing the number of available template copies, and is thus not a suitable alternative when template molecules are expected to be minimal.
Each fragment was amplified and cloned into a pGEM-T easy vector (Promega), and serial dilutions of the plasmids were used to create standard curves.
Dilution leads to easier access of DNase to genomic DNA and probably allows more efficient phenol extraction due to lower viscosity of the sample.
In summary, we performed a comparative study on the effect of spermidine onto PCR efficiency reporting that spermidine addition is easier and more useful than dilution or purification methods and that it can dramatically improve the quantification of methylation values.
Possibly, hormesis is more easy to observe at ultra-low dilutions with single chemicals than with complex preparations.
For the construction of standard curves, pGEM-T easy plasmids were prepared as 10-fold serial dilution in water, from 4 ng to 0.4 pg.
