Biological Activity
Description: Standard reference
In vitro:
Phytochemistry. 2012 Apr;76:32-9.
IeCPS2 is potentially involved in the biosynthesis of pharmacologically active Isodon diterpenoids rather than gibberellin.[Pubmed: 22284743]

METHODS AND RESULTS:
Based on tissue-specific expression and metabolic localization studies, the IeCPS2 transcripts were detected in young and mature leaves where the dominant ent-kaurane diterpenoid Maoecrystal B accumulates, whereas no detectable expression of IeCPS2 was observed in germinating seeds where the gibberellin biosynthetic pathway is usually active. In addition, no evidence for Maoecrystal B was found in germinating seeds. On the other hand, IeCPS1 transcripts significantly accumulated in germinating seeds as well as in leaves.
CONCLUSIONS:
The biochemical and molecular genetic evidence thus indicated that IeCPS2 is a copalyl diphosphate synthase potentially involved in the biosynthesis of Isodon diterpenoids in leaves, while IeCPS1 is more probably relevant to gibberellin formation and may, in addition, participate in Isodonent-kaurane diterpenoid production.

Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.
