You are likely referring to pGPTv and pET vector. Here is the difference:
- pGPTv: Plasmid-based Gateway recombinational cloning technology, used for cloning and recombining genes.
- pET vector: An expression vector used to produce proteins in bacterial systems like E. coli.
Key differences:
| Feature | pGPTv | pET vector |
|---|---|---|
| Purpose | Cloning and recombining genes | Expression of proteins |
| Type | Cloning vector | Expression vector |
| Mechanism | Gateway recombination | Transcription and translation |
Summary: pGPTv is a tool for efficiently cloning genes, while pET is used to produce large quantities of protein from those genes.
