活体转基因--钳状电极用于体内**/基因/蛋白质传递及基因**电极.
活体转基因--钳状电极Tweezertrodes是一种可复用的小钳状电极,主要用于体内的**或基因的传递。电极是一个标准的11.5厘米的小钳子,其尖部为嵌入的不锈钢圆盘状电极,两盘的间隙可调至2厘米,并有一个阳极指示器。
活体转基因--钳状电极Tweezertrodes电极有两种规格,45-0118为直径:7mm的电极盘,45-0119为直径:10mm的电极盘
当把感兴趣的分子注射到体内后,用电极盘夹住相关组织,然后给出电脉冲,使孔道开始形成,将分子整合到直接与电极盘接触的组织细胞内。

Tweezertrodes are reusable, tweezer-style in vivo electrodes fordrug or gene delivery in animals. Tweezertrodes consist of astandard 11.5 cm tweezer that has been modified with stainlesssteel circular or disk electrodes at the tip. The gap between theelectrode disks may be adjusted from under 1 mm to over 2 cm.Tweezertrodes come in two models. Model 520 has an electrode diskdiameter of 7 mm and Model 522 has a diameter of 10 mm.Tweezertrodes may be cleaned with a mild detergent and sterilizedwith ethanol or ethylene oxide. These electrodes are connected to apulse generator with the Model 524 Connection Cable, and arecompatible with most BTX Electroporation System
Applications

Tweezertrodes may be used for many in vivo applications, includinggene and drug delivery. Following localized or systemic injectionof the molecule of interest, the Tweezertrode electrode disks areused to grasp the tissue of interest. An electroporation pulse isthen given, initiating pore formation and incorporation of themolecule into the cells of the tissue in direct contact with theelectrode disks. Suzuki et al. used Tweezertrodes to deliver aGreen Fluorescent Protein (GFP) gene into rat liver. The authorsdemonstrated successful gene transfer and expression in situ.1,2Saito and Nakatsuji used a similar electrode to introduce plasmidDNA during ex-utero and in-utero electroporation.7 Sato et al. usedthe Tweezertrode with the T820 to introduce EGFP expressing plasmidin mouse testis.8 Tweezertrodes complement BTX Genetrode Models508, 510, Caliper Electrode Models 384 and 384L, 2-Needle ArrayModels 530 and 532 as the newest addition to our in vivo electrodeline. The Tweezertrodes can be used to reproduce applicationsrequiring the caliper electrodes, including gene therapy,transdermal drug delivery and electroporation therapy.3,4,5,6
