Folic Acid (Folic Acid), also known as pteroyl glutamate, is a water-soluble vitamin, is a light orange yellow crystal or sheet, the molecular formula is C19H19N7O6, the molecular weight is 441.4 because of the rich content in green leaves. There are several forms in nature, and its parent compound is a combination of pteridine, p-aminobenzoic acid and glutamic acid. PEG derivatives are also known as PEG (polyethylene glycol) modifiers, modifying PEG, etc. PEG is a functional group that is currently mainly used for protein drug modification to increase the half-life in vivo and reduce immunogenicity, while also increasing the water solubility of the drug. PEG derivatives have been widely used in pharmaceutical research and development in recent years, and play an important role in the sustained release of drugs. DOPE Conjugate pegylates are phospholipids and pegylates combined with hydrophilic and hydrophobic properties. Polyethylene glycol phospholipid liposome forming material can be used for drug delivery, gene transfection and vaccine delivery.

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.
Wherever possible, you should prepare and use solutions on the same day.
