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.

Unprecedented polyketides from a marine sponge-associated Stachylidium sp.[Pubmed:
23268694 ]
METHODS AND RESULTS:
From the marine sponge-derived fungus Stachylidium sp. six novel phthalide-related compounds, cyclomarinone (1), maristachones A-E (2-5), and Marilactone (6), were isolated. The structure of compound 1 comprises a hydroxycyclopentenone ring instead of the furanone ring characteristic for phthalides and represents a new carbon arrangement within polyketides. In the epimeric compounds 5a and 5b the phthalide (=isobenzofuranone) nucleus is modified to an isobenzofuran ring with ketal and acetal functionalities.
CONCLUSIONS:
Biosynthetically the structural skeletons of cyclomarinone (1) and maristachones A (2), C (4), D (5a), and E (5b) are most unusual due to the presence of an additional carbon atom when compared to the basic polyketide skeleton.
This special biosynthetic feature also holds true for the likewise isolated polyketide Marilactone (6).
