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.

    Anti-Inflammatory Effect of Lupinalbin A Isolated from Apios americana on Lipopolysaccharide-Treated RAW264.7 Cells.[Pubmed: 29509670 ]
    Apios americana, a leguminous plant, is used as food in some countries. Although the biological activities of Apios extract have been reported, there have been no reports about the anti-inflammatory mechanism of Lupinalbin A on the RAW264.7 cells.
    METHODS AND RESULTS:
    In this study, we investigated the anti-inflammatory effect of A. americana Lupinalbin A on lipopolysaccharide (LPS)-treated RAW264.7 cells. Lupinalbin A significantly inhibited nitric oxide production and inducible nitric oxide synthase expression in LPS-treated RAW264.7 cells. The expression of cytokines, including interleukin-6, tumor necrosis factor-α, and chemokine of monocyte chemoattractant protein, was reduced under Lupinalbin A exposure in LPS-treated RAW264.7 cells. In addition, Lupinalbin A significantly decreased LPS-induced interferon (IFN)-β production and STAT1 protein levels in RAW264.7 cells.
    CONCLUSIONS:
    Taken together, these results suggest that A. americana Lupinalbin A exerts anti-inflammatory effects via the inhibition of pro-inflammatory cytokines and blocking of IFN-β/STAT1 pathway activation.

    Lupinalbin A as the most potent estrogen receptor α- and aryl hydrocarbon receptor agonist in Eriosema laurentii de Wild. (Leguminosae).[Pubmed: 25106881 ]
    Eriosema laurentii De Wild. (Leguminosae) is a plant used in Cameroon against infertility and gynecological or menopausal complaints. In our previous report, a methanol extract of its aerial parts was shown to exhibit estrogenic and aryl hydrocarbon receptor agonistic activities in vitro and to prevent menopausal symptoms in ovariectomized Wistar rats.
    METHODS AND RESULTS:
    In order to determine the major estrogen receptor α (ERα) agonists in the extract, an activity-guided fractionation was performed using the ERα yeast screen. To check whether the ERα active fractions/compounds also accounted for the aryl hydrocarbon receptor (AhR) agonistic activity of the crude methanol extract, they were further tested on the AhR yeast screen. This study led to the identification of 2'-hydroxygenistein, Lupinalbin A and genistein as major estrogenic principles of the extract. 2'-hydroxygenistein and Lupinalbin A were, for the first time, also shown to possess an AhR agonistic activity, whereas genistein was not active in this assay. In addition, it was possible to deduce structure-activity relationships.
    CONCLUSIONS:
    These results suggest that the identified compounds are the major active principles responsible for the estrogenic and AhR agonistic activities of the crude methanol extract of the aerial parts of Eriosema laurentii.
