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.

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.

Effect of esculentoside H on release of tumor necrosis factor from mouse peritoneal macrophages.[Pubmed:
8010057]
METHODS AND RESULTS:
Effect of Esculentoside H (EH) on release of tumor necrosis factor (TNF) from murine peritoneal macrophage (Mphi) in vitro was studied. The results showed that Esculentoside H (12.5-200 micrograms.ml-1) induced the thioglycolate-broth elicited peritoneal Mphi to release TNF into supernatants in a dose-dependent manner, and higher levels of TNF activity were detected in the supernatants from Esculentoside H-stimulated calcimycin-primed Mø culture. Esculentoside H-induced TNF release had a different type of kinetics compared with that of lipopolysaccharides (LPS). LPS-induced release of TNF increased rapidly until 6 h after LPS stimulation, then declined gradually, while Esculentoside H-induced TNF release increased gradually after Esculentoside H stimulation and reached its peak at approximately 24 h later.
CONCLUSIONS:
These results suggested that the anti-tumor mechanisms of Phytolaccaceae may be related to the capacity of Esculentoside H for TNF release.
