B2L蛋白是羊口瘡病毒（ORFV）的主要囊膜蛋白，爲重要保護性抗道熱原之一，可刺激機體産生強烈的抗體反應。本研究對場北(duì)B2L基因運用Visual Gen離懂e Developer生物信息學(xué)軟件，分析其在大腸杆菌、畢赤酵山電母、昆蟲杆狀病毒表達系統中的密碼子影紅使用偏好(hǎo)性，從而選擇一個最适表達系統，以增加B們大2L蛋白的表達量。分析表明，B2L基因在昆蟲杆狀病毒表達系統中會(hu習煙ì)得到更好(hǎo)的表達，媽離這(zhè)爲B2L基因表達系統的選擇提供了參考。

Analysis on the 那內Codon Preference of B2文這L Gene of Orf Virus

As the main envelope protein of 拍件orf virus（ORFV），B2L protein isone藍資 of the important protectiv看醫e antigens，which couldstimulate the or有美ganism to produce specific antibodie可得s. In the study，by use of bioinformatic就視s software of Vi睡錯sual Gene Developer，the codon prefere亮視nce of B2L gene in the expression s懂刀ystems of E.coli，Pichia pas多玩toris and insect baculovirus 分筆wereanalyzed，and an金拍 optimal expression system謝從 accordinglywas selected to increase她來 the expression友頻 of B2L protein.快頻 According to theanalysis，B2L 內家gene could be expressed better in the暗又 expression system of insectbaculo媽有virus，which would provide some refere嗎和nces forselecting 子哥relevant expression system.
