■ 質粒簡介
pCDNA3.1(-)是來自pCDNA3的5.4kb載體，設計用于哺乳動物宿主中的高水平穩(wěn)定和瞬時表達。大多數(shù)哺乳動物細胞可以進行高水平的穩(wěn)定和非復制性瞬時表達。人類巨細胞病毒立即早期（CMV）啟動子，用于在廣泛哺乳動物細胞中的高水平表達。前向（+）和反向（-）方向上的多個克隆位點，以促進克隆用于選擇穩(wěn)定細胞系的新霉素抗性基因。在潛伏感染SV40或表達SV40大T抗原（例如COS-1，COS-7）的細胞系中的異常復制。 質粒只保證關鍵序列正確，不保證表達效果。
pCDNA 3.1(-) is 5.4 kb vector derived from pcDN3 and designed for high-level stable and transient expression in mammalian hosts. High-level stable and non-replicative transient expression can be carried out in most mammalian cells. The vectors contain the following elements:
Human cytomegalovirus immediate-early (CMV) promoter for high-level expression in a wide range of mammalian cells
Multiple cloning sites in the forward (+) and reverse (C) orientations to facilitate cloning
Neomycin resistance gene for selection of stable cell lines
Episomal replication in cells lines that are latently infected with SV40 or that express the SV40 large T antigen (e.g. COS-1, COS-7)
The control plasmid, pcDNA3.1/CAT, is included for use as a positive control for transfection and expression in the cell line of choice.
Use the following outline to clone and express your gene of interest in pcDNA 3.1.
1. Design the multiple cloning
2. Ligate your insert into the appropriate vector and transform into E. coli. Select transformants on LB plates containing 100 g/ml ampicillin
3. Analyze your transformants for the presence of insert by restriction digestion.
4. Select a transformant with the correct restriction pattern and use sequencing to confirm that your gene is cloned in the proper orientation.
5. Transfect your construct into the mammalian cell line of interest using your own method of choice. Generate a stable cell line, if desired.
6. Test for expression of your recombinant gene by western blot analysis or functional assay.
