简单介绍:
用于许多体内,离体,卵内电穿孔基因转移,包括药物及基因的传递。
详情介绍:
BTX Genetrodes是一种成对针式可重复使用的电极。它是体内,卵内电穿孔,包括药物基因转移的理想选择。Genetrodes有五种型号可供选择,以适应各种电穿孔领域的不同尺寸形状要求。每种型号包括一对金质电极针,有直头和L型两种。在注入感兴趣的分子后,将电极放入组织中,用BTX电穿孔系统施加电脉冲,所产生的电场会使组织细胞上出现短暂的通道,允许分子摄入胞内。电极可以用电极夹持器在组织内以一种预设的间隙平行放置。
BTX Genetrodes are needle-style reusable electrodes that are used for a variety of applications. Genetrodes come in five models, with each model consisting of a pair of electrodes. The Model 508 and 510 Genetrodes are straight electrodes with gold tips. The Model 512, 514, and 516 Genetrodes are bent L-shaped electrodes with gold tips. These electrodes are connected to a Model 465 Square-Post Connection Cable and interfaced with a pulse generator via a Model 5343 Coaxial-Banana Connection Cable. The Genetrodes are positioned in parallel at a predetermined gap within a tissue using the Model 515 Genetrode Holder. Genetrodes may be cleaned with a mild detergent and sterilized with ethanol or ethylene oxide. Properly maintained Genetrodes have a life span of approximately 1500+ pulses, and are compatible with most BTX Electroporation Systems.

Applications

General Applications: Genetrodes may be used for many in vivo and in ovo electroporation applications, including drug and gene delivery. The electrodes are placed into a tissue following injection of the molecule of interest, and an electroporation pulse is delivered using a BTX Electroporation System, such as the ECM 600, 630, 830, T820 or 2001. The electric field introduced by the Genetrodes causes transient pores to form in the cells of the tissue, allowing uptake of the molecules into the cells.

In Vivo Applications: Model 508 and Model 510 Genetrodes: The model 508 Genetrode with a sharp 5mm electrode tip is a general in vivo electrode. The model 510 is the same electrode but with a 10mm tip. Genetrodes have been used for a variety of applications. Eide et al. used the Genetrodes along with the ECM 830 to introduce plasmid DNA into free swimming embryonic Xenopus laevis.2 Dean et al. used the Genetrodes on mouse cornea, which resulted in a 30-fold higher expression than that obtained with Lipofectin.3 Murphy et al. used the Genetrodes with ECM 830 to introduce plasmid DNA into a mouse cerebellum, where he concluded that electroporation is a viable means of transferring genes to the central nervous system.4 Aihara and Miyazaki used these electrodes with a T820 to transfer genes into murine muscle tissue, significantly increasing expression levels over DNA injection alone.5

In Ovo Applications: Model 512, 514, and 516 Genetrodes: The model 512, 514, and 516 electrodes are all suitable for in ovo gene transfer studies. Kos used the Genetrodes with the T820 to successfully introduce expressing plasmids and morpholino antisense oligonucleotides in ovo 1 and Paquette et al. used the Genetrodes to drive plasmid DNA into the neural tube of a developing egg in which widespread gene expression was observed.9 An electrode similar to model 514 has been used with a T820 by Muramatsu in his in ovo studies.5 He concludes that electroporation is superior to both lipofection and microparticle bombardment.6
