美国BIO－RAD转基因仪微粒导入仪 (基因枪)：Biolistic PDS-1000

Biolistic PDS-1000/He 基因枪系统将微米大小的、包被有核酸的金或钨微粒加速到所需要的速度，从而将基因导入细胞、组织或器官。这一过程既不依赖也不作用于细胞表面。系统利用高压氦气的轰击，来推动携带有微粒的塑料大颗粒载体盘朝目标细胞方向加速。推进大颗粒载体的氦气压力由所使用的不同破裂盘决定。破裂盘是一种可在特定压力下破裂的塑料密封体。终止屏可阻止大颗粒载体，使微粒可以通过和转染靶细胞。为了提高这一进程的效率，可抽空转化室，使压力低于大气压力，从而当微粒打向靶细胞时可减
少其摩擦阻力。
Biolistic PDS-1000/He 系统能提供：
• 一种可重复的、转化完整培养细胞的方法，几乎无需对细胞进行处理
• 用其它方法不能完成的，有特殊生长需要的细胞转化
• 实验过程的最大控制
• 高重复性
The Biolistic pds-1000 /He gene gun system accelerates micron-sized particles of gold or tungsten coated with nucleic acid to the desired speed to introduce genes into cells, tissues or organs.This process does not depend on or act on the cell surface.The system USES a blast of high-pressure helium gas to propel a large plastic carrier carrying tiny particles in a disk toward the target cell.The helium pressure to propel the large particle carrier is determined by the different rupture disks used.A rupture disc is a plastic seal that can break under certain pressures.The termination screen prevents the carrier of large particles, allowing the particles to pass through and transfect the target cells.To improve the efficiency of this process, the chamber can be evacuated so that the pressure is lower than the atmospheric pressure, which can be reduced when the particles hit the target cells Less frictional resistance
Biolistic pds-1000 /He system can provide:
• a repeatable method of transforming fully cultured cells with little or no cell processing
• cell transformation that cannot be accomplished by other methods and has special growth needs
• maximum control of the experimental process
• high repeatability
