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.

Filamenting temperature-sensitive mutant Z inhibitors from Glycyrrhiza glabra and their inhibitory mode of action.[Pubmed:
28196701]
FtsZ is an essential protein for bacterial cell division, and an attractive and underexploited novel antibacterial target protein.
METHODS AND RESULTS:
Screening of Indonesian plants revealed the inhibitory activity of the methanol extract of Glycyrrhiza glabra on the Bacillus subtilis FtsZ (BsFtsZ) GTPase, and further bioassay-guided fractionation of the active methanol extract led to the isolation of seven known polyketides (1-7). Among them, Gancaonin I (1), glycyrin (3), and isolicoflavanol (5) exhibited anti-BsFtsZ GTPase activities, at levels comparable to that of the synthetic FtsZ inhibitor, Zantrin Z3. Enzymatic assays using a BsFtsZ Val307R mutant protein and in silico simulations suggested that 1, 3, and 5 bind to the cleft on BsFtsZ, as in the case of the previously reported uncompetitive FtsZ inhibitor, PC190723, and thereby display their significant anti-BsFtsZ inhibitory activities. Furthermore, 1 also showed significant inhibitory activity against B. subtilis, with a MIC value of 5μM.
CONCLUSIONS:
The present study provides new insights into the naturally occurring B. subtilis growth inhibitors.
