【慢病毒載體和病毒 (Lentiviral Vectors & Virus)】Viral Expression Systems ABMGOOD
病毒表達系統(Viral Expression Systems) 慢病毒載體和病毒 (Lentiviral Vectors & Virus)
基因傳遞(Gene delivery )是將遺傳物質( genetic material)引入宿主細胞以改變細胞功能(cell function),從而能夠研究生物功能背後的分子機制(molecular mechanisms )和調控。 科學家透過設計重組病毒傳遞系統,利用了病毒將 DNA 轉運( transport DNA)到細胞中的天然能力。這些是體內和體外基因編輯( gene editing)和基因治療(gene therapy_的新時代。在可用的病毒表現系統中,最常用的包括慢病毒(Lenti-)、腺病毒(Adeno-)、AAV、逆轉錄病毒、HSV 和桿狀病毒( Baculoviral systems)系統,無論您想要過度表現或敲低一個基因或多個基因,abm 的世界-領先的即用型套件並將任何基因傳遞到每個項目的任何細胞類型。另提供Lentivirus慢病毒低速30分純化套組(純化) 、Lentivirus 慢病毒高濃度純化套組(純化) 兩種不同力價的純化套組,Lentivirus病毒一個步驟QPCR定量套組(定量)。
SHOX2 慢病毒載體 (Human) (pLenti-GIII-CMV) | 貨號43729061 (1.0 µg DNA)
SHOX2 Lentiviral Vector (Human) (CMV) (pLenti-GIII-CMV) SHOX2 慢病毒載體(人類)(CMV)(pLenti-GIII-CMV)
CD80 Lentiviral Vector (Mouse) (NM_003030.4) 架構於pLenti-GIII-CMV 表現載體上,架構成SHOX2 Lentiviral Vector (Human) (CMV) (pLenti-GIII-CMV)。慢病毒載體,可結合packaging mix (改良式 病毒包裝系統 LV003) 以在多種宿主細胞或動物模型中過表達目標miRNA。 該構建體含有用於監測轉染效率的GFP報告基因(GFP reporter ),可以Monitor轉染效率。可直接以非病毒質粒轉染 (non-viral plasmid transfection) 立即表達目標蛋白,或經由包裝成慢病毒顆粒,實現高效轉導和穩定整合的表達目標蛋白。
病毒表達系統(Viral Expression Systems)
慢病毒系統的優點:Advantages of the Lentivirus System
- 大插入容量(高達 9kb)
- 感染效率高
- 廣泛的宿主範圍(分裂、非分裂、幹細胞和原代細胞)
- 重組蛋白的穩定整合與表達
- 非常適合創建穩定的細胞系

慢病毒感染通用指引感染複數 (Lentivirus Infection Multiplicity of infection , MOI) 是病毒顆粒(viral particles)與標靶細胞(target cells)的比率。慢病毒感染通用指引 感染複數 (Lentivirus Infection Multiplicity of infection , MOI)為 10 表示培養容器中每個細胞有 10 個病毒顆粒。使用的最佳感染複數 (MOI) 將根據您的目標細胞係而有所不同。以下是常用癌細胞株和建議的感染 MOI 清單:
如果您的標靶細胞不在清單中,我們建議您在初步研究中以報告慢病毒(即 Lenti-GFP,abm 目錄號 LV006)感染您的目標細胞,以確定最佳 MOI。為了增加感染性,請在 8 µg/ml 的聚凝胺(abm 目錄號 G062)和/或 1:100 稀釋的 ViralPlus(abm 目錄號 G698)存在的情況下進行病毒感染。請參閱我們的慢病毒感染方案,以了解詳細的逐步感染流程。
Abmgood提供一系列序列驗證開放閱讀框(Open Reading Frame, ORF)庫,包括人(human),小鼠(mouse)和大鼠(rat),可insertion至您選擇的蛋白質表達系統(protein expression systems.)。去除5’UTR和3’UTR,ORF插入兼容的表達載體(compatible expression vector) 後即可快速可靠地表達蛋白質。也可用作PCR擴增 (PCR amplification experiments) 實驗中陽性對照(positive control)的模板(template)。Abmgood提供的ORF包含一個突變的終止密碼子(mutated stop codon),如果受體載體中存在C末端標籤或報告基因,則允許其摻入。 abm的ORF也可以以即用型蛋白表達載體(protein expression vectors),慢病毒載體(lentiviral vectors)或包裝的慢病毒( Lentivirus)和AAV、腺病毒( Adenovirus )之架構好之載體或病毒液形式提供。
