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.

Background on Brassinolide

IC50: N/A

Brassinolide is a plant growth regulator. Plant growth regulators are naturally produced by plants and are critical for regulating their own growth. Plant growth regulators act via modifying or controlling plant growth processes, such as leave and flower formation, stem elongation, as well as fruit development and ripening.

In vitro: Brassinolide induced the time and concentration-dependent cytotoxicity in PC-3 cells. The mode of such cell death appeared to be apoptosis predominately, as demonstrated by fluorescence, flow-cytometric analyses and transmission electron microscopes. Moreover, Caspase-3 activity was increased after brassinolide treatment obviously. Western blot studies showed brassinolide treatment triggered a time-dependent decrease in the expression of Bcl-2 [1].

In vivo: Brassinolide had the similar function of reducing the blood glucose levels as phenformin, but without the dose-dependent manner. The blood glucose levels showed significant differences after brassinolide treatment with different doses (200, 100, and 50 mg/kg). These results indicated that brassinolide could reduce the blood glucose levels without toxicity [2].

Clinical trial: So far, no clinical study has been reported.

References on Brassinolide

Effect of epibrassinolide on hypocotyl growth of the tomato mutant diageotropica.[Pubmed:11536896]

Planta. 1998 Dec;207(1):120-4.

The effect of epiBrassinolide (epiBR) on the growth and gravitropism of hypocotyls was investigated in diageotropica (dgt), a mutant of tomato (Lycopersicon esculentum Mill.). The elongation of (dgt) hypocotyls, which had been reported to be auxin-insensitive, was promoted by increasing concentrations of indole-3-acetic acid (IAA) in the presence of epiBR. alpha-(p-Chlorophenoxy)isobutyric acid, an inhibitor of auxin action, blocked the enhancement of growth by IAA and epiBR. Time course analysis of IAA-induced dgt hypocotyl elongation in the presence of epiBR revealed typical auxin response kinetics. These results suggest that epiBR restores the auxin responsiveness of dgt hypocotyls with respect to elongation. However, epiBR did not rescue the dgt phenotype with respect to shoot gravitropism. It was therefore concluded that brassino-steroid insensitivity or deficiency is not the primary defect of the dgt mutation.
