General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

DNA-binding affinities and sequence specificities of protoberberine alkaloids and their demethylated derivatives: a comparative study.[Pubmed: 17311227]


METHODS AND RESULTS:
Berberrubine (1a), jatrorubine (2a), and Palmatrubine (3a) have been chemically prepared by partial demethylation of berberine (1), jatrorrhizine (2), and palmatine (3), respectively. Their interactions with calf thymus (CT) DNA, poly(dA-dT)poly(dA-dT), poly(dG-dC)poly(dG-dC), and eight AT-rich 12-mer double-stranded DNAs have been investigated by means of competitive ethidium bromide (EB) displacement experiments. The results showed that DNA-binding affinities of these protoberberine alkaloids have been significantly improved by partial demethylation, and that all of these alkaloids have the preferable binding affinities with AT-rich DNA. Especially, the sequence specificities of DNA-binding of demethylated derivatives 1a, 2a, and Palmatrubine had changed to a certain extent when compared with the parent alkaloids 1, 2, and 3, respectively. The binding mode of these alkaloids was further confirmed by UV spectroscopic titration experiments.
CONCLUSIONS:
All the compounds bind to double-stranded DNA most probably via an intercalating mode.
