    Storage: 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.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: 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.

    Protective effects of liquiritin apioside on cigarette smoke-induced lung epithelial cell injury. [Pubmed: 21631586]
    We hypothesized that Liquiritin apioside (LA), a main flavonoid component from Glycyrrhiza uralensis, had antioxidant properties by inducing glutathione (GSH) biosynthesis via the inhibition of cytokines and protected lung epithelial cells against cigarette smoke-mediated oxidative stress. A549 cells were treated with cigarette smoke extract (CSE) and/or Liquiritin apioside. ICR mice were exposed to cigarette smoke (CS) for four days with increasing exposure time for up to 6 h per day to elicit epithelial cells injury. One hour before smoke exposure, mice were treated with Liquiritin apioside by gavage; 18 h after the last CS exposure all examinations were performed. Treatment with Liquiritin apioside concentration-dependently prevented CSE-induced cytotoxicity, increase of TGF-β and TNF-α mRNA expression, depletion of GSH and apoptosis in A549 cells. Liquiritin apioside at doses 3, 10 and 30 mg/kg dose-dependently inhibited pulmonary neutrophil and macrophage inflammation. Lung sections of the CS-exposed Liquiritin apioside treated mice showed an apparently reduced pulmonary inflammation and a significant inhibitory effect on mucus containing goblet cells in the large airways. Furthermore, the CS-induced pulmonary release of TGF-β, TNF-α and myeloperoxidase activity was reduced, and superoxide dismutase activity was enhanced.These results indicate that protective roles of Liquiritin apioside on CS-induced the lung epithelial cell injury are mediated by inhibiting TGF-β and TNF-α expression and increasing anti-oxidative levels of GSH, suggesting that Liquiritin apioside might be effective as protective agent against epithelial injury in COPD.
