美國(guó) Bio-rad轉(zhuǎn)基因儀基因槍系統(tǒng)Helios

顆粒轟擊用于體外和體內(nèi)基因轉(zhuǎn)移的優(yōu)點(diǎn)

* 簡(jiǎn)單、快速、功能靈活的基因傳送，各種細(xì)胞類型通用
* 有助于瞬時(shí)表達(dá)和穩(wěn)定表達(dá)
* 只需少量的DNA 和細(xì)胞
* 無需載體DNA
* 能進(jìn)行多質(zhì)粒共同導(dǎo)入
* 輸送大片段DNA
* 胞內(nèi)目標(biāo)基因可導(dǎo)入多個(gè)細(xì)胞
* 用于體內(nèi)和體外轉(zhuǎn)化
* 沒有無關(guān)的基因或蛋白被轉(zhuǎn)導(dǎo)

The Helio gene gun is a convenient portable device for rapid and direct in-situ gene transfer of cells.The system USES an adjustable pulse of helium gas to drive gold particles of DNA, RNA or other biomaterials prepacked on the inside of a small plastic tube directly into a cell.The in-tube "bullet" can be easily prepared using the sample control station.

The advantages of particle bombardment for gene transfer in vitro and in vivo

* simple, fast, functional gene transfer across all cell types

* contributes to transient and stable expression

* only small amounts of DNA and cells are needed


* no carrier DNA is required

* multiple plasmids can be imported together

* transport large fragments of DNA

* target genes can be introduced into multiple cells

* for in vivo and in vitro transformation
