In 2004, the Company also launched the "throwing power gold nucleic acid drinks," the replacement Product --- throwing force oral liquid gold.

泼力金核酸饮品一上市，就以口感好、易吸收、效果确切等特点，受到广大顾客尤其是中老年人的青睐。2004年，本公司又推出了&泼力金核酸饮品&的换代产品---泼力金口服液。

Peptide nucleic acid is a kind of new nucleic acid mimic invented in the early 1990s', in which the deoxyribose phosphate backbone has been replaced by a pseudo-peptide polymer to which the nucleobases are linked. PNA is uncharged, highly stable in chemical and biological environments, and binds complementary DNA and RNA targets with remarkably high affirnity and specificity.

肽核酸是二十世纪九十年代初合成的一种全新的核酸类似物，它以多肽骨架完全替代DNA中的脱氧核糖磷酸二酯键的骨架，呈电中性，具有极高的生物和化学稳定性、极强的核酸结合能力和特异性，在分子生物学的许多方面得到广泛应用。
