BioVector® pLIB biGbac 系统载体 / BioVector® pLIB biGbac System Vector
通用定义 / General Definition:BioVector® pLIB 在 biGbac 系统中扮演着核心角色。biGbac 是一种基于 Gibson Assembly(吉布森组装) 的高效多基因表达平台,专门用于在昆虫细胞(如 Sf9, High Five)中通过杆状病毒表达系统表达复杂的大型多亚基蛋白质复合物。在 biGbac 工作流程中,pLIB 载体作为一级克隆载体(Level 1),用于接收和储存单个基因。随后,多个 pLIB 载体中的基因片段可以被组装进二级载体(Level 2,如 pBIG1 或 pBIG2),最终实现多个基因的同时高水平表达。
In the biGbac system, BioVector® pLIB serves as the fundamental Level 1 cloning vector. The biGbac system is a high-efficiency multi-gene expression platform based on Gibson Assembly, specifically designed for expressing large, multi-subunit protein complexes in insect cells (e.g., Sf9, High Five) using the Baculovirus Expression Vector System (BEVS). Within the biGbac workflow, pLIB vectors hold individual genes. These gene cassettes are then assembled into Level 2 vectors (such as pBIG1 or pBIG2) to achieve the simultaneous, high-level expression of multiple genes from a single baculoviral genome.

4. Key Usage Notes
Flanking Sequences: Each pLIB variant (e.g., pLIB-1, pLIB-2) contains unique linker sequences. It is critical to select the correct pLIB position according to the biGbac assembly logic.
Sequence Integrity: Before proceeding to Level 2 assembly, ensure the gene insert within pLIB is verified using BioVector® sequencing services to confirm 100% accuracy.
Note: For optimal Gibson Assembly efficiency, use the BioVector® biGbac Assembly Master Mix. When purifying pLIB plasmids for large-scale assembly, ensure high DNA concentration and purity using BioVector® Plasmid Midi Kits.
