摘要:
The invention provides a free radical-induced intracellular DNA damage reducing reagent, including: an effective amount of a Gracilaria sp. extract, serving as an active ingredient, wherein the free radical-induced intracellular DNA damage reducing reagent is capable of reducing free radical-induced intracellular DNA damage. The invention also provides a free radical-induced intracellular DNA damage reducing medicament or health food and a free radical-induced intracellular DNA damage reducing skin care product or cosmetic.
摘要:
The invention describes compositions and methods for recombinant protein expression in a wide range of cell types, including mammalian, insect, and bacterial cells. The compositions comprise a viral IRES sequence selected from enterovirus 71 (EV71), hepatitis C virus (HCV), or encephalomyocarditis virus (EMCV), or a variant or fragment thereof, or alternatively, a homolog of a viral IRES selected from EV71, HCV, or EMCV, or a variant or fragment thereof. Methods of using the compositions are also described.
摘要:
Polypeptides each having a target sequence that contains a recognition site of a protease and is flanked by a first heterologous sequence and a second heterologous sequence. Disclosed are nucleic acids encoding the polypeptides, and vectors and host cells having the nucleic acids. Also disclosed are systems containing the polypeptides or the nucleic acids and use of the systems.
