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.

Lanostanoids with acetylcholinesterase inhibitory activity from the mushroom Haddowia longipes.[Pubmed: 25577284
METHODS AND RESULTS:
Nine lanostanoids, together with nine known ones, were isolated from the ethyl acetate extract of the fruiting bodies of the mushroom Haddowia longipes. Their structures were elucidated as 11-oxo-ganoderiol D, lanosta-8-en-7,11-dioxo-3β-acetyloxy-24,25,26-trihydroxy, lanosta-8-en-7-oxo-3β-acetyloxy-11β,24,25,26-tetrahydroxy, lanosta-7,9(11)-dien-3β-acetyloxy-24,25,26-trihydroxy, lanosta-7,9(11)-dien-3β-acetyloxy-24,26-dihydroxy-25-methoxy, 11-oxo-Lucidadiol, 11β-hydroxy-Lucidadiol, lucidone H and lanosta-7,9(11),24E-trien-3β-acetyloxy-26,27-dihydroxy by analysing their 1D/2D NMR and MS spectra.
In addition, bioassays of inhibitory activity against acetylcholinesterase (AChE) of all compounds showed that thirteen compounds possessed inhibitory activity against AChE with the percentage inhibition ranging from 10.3% to 42.1% when tested at 100 μM.

Selective cholinesterase inhibition by lanostane triterpenes from fruiting bodies of Ganoderma lucidum.[Pubmed: 21924611
METHODS AND RESULTS:
Two new lanostane triterpenes, named methyl ganoderate A acetonide (1) and n-butyl ganoderate H (2), were isolated from the fruiting bodies of Ganoderma lucidum together with 16 known compounds (3-18). Extensive spectroscopic and chemical studies established the structures of these compounds as methyl 7β,15α-isopropylidenedioxy-3,11,23-trioxo-5α-lanost-8-en-26-oate (1) and n-butyl 12β-acetoxy-3β-hydroxy-7,11,15,23-tetraoxo-5α-lanost-8-en-26-oate (2). Because new compounds exhibiting specific anti-acetylcholinesterase activity are being sought as possible drug candidates for the treatment of Alzheimer's and related neurodegenerative diseases, compounds 1-18 were examined for their inhibitory activities against acetylcholinesterase and butyrylcholinesterase. All of the compounds exhibited moderate acetylcholinesterase-inhibitory activity, with IC(50) values ranging from 9.40 to 31.03μM. In contrast, none of the compounds except Lucidadiol (13) and lucidenic acid N (14) exhibited butyrylcholinesterase-inhibitory activity at concentrations up to 200μM.
These results indicate that these lanostane triterpenes are preferential inhibitors of acetylcholinesterase and may be suitable drug candidates.
