活體轉(zhuǎn)基因--卡鉗電極

活體轉(zhuǎn)基因--卡鉗電極384L 用于體內(nèi)肌肉基因/藥物傳遞電極

BTX Caliper電極是一種體內(nèi)可復(fù)用的卡鉗狀測(cè)徑器電極，有多種應(yīng)用，如在體內(nèi)進(jìn)行基因和藥物的傳遞，也可經(jīng)皮膚應(yīng)用及在完整的植物上應(yīng)用。該電極由一個(gè)測(cè)徑器和一對(duì)末端電極組成，共有兩種類(lèi)型：45-0101型的末端為一對(duì)1x1cm黃銅制末端電極，適用于小動(dòng)物，45-0102型的末端為一對(duì)1.5x1.5cm或2x2cm的不銹鋼制末端電極，適用于較大的區(qū)域表面，兩電極間的距離可以調(diào)節(jié)。

活體轉(zhuǎn)基因當(dāng)把感興趣的分子注射到體內(nèi)以后，用電極板夾住相關(guān)目標(biāo)組織，然后給出電脈沖，電場(chǎng)通過(guò)電極在組織細(xì)胞間形成暫時(shí)的孔道，使分子進(jìn)入到與電極接觸的組織細(xì)胞內(nèi)。

The BTX Caliper Electrodes are in vivostyle re-usable electrodes that are used for a variety ofapplications. Caliper Electrodes come in two models, with eachmodel consisting of a caliper and a pair of end plates. Model 384are used for smaller animals with a smaller surface area, whilemodel 384L is used to target slightly larger surface areas. The endplates of the Caliper Electrode may be adjusted by using the blackroller mounted on the caliper. Caliper Electrodes may be cleanedwith a mild detergent and sterilized with ethanol or ethyleneoxide. Properly maintained Caliper Electrodes have an unlimitedlife, and are compatible with most BTX Electroporation Systems.

活體轉(zhuǎn)基因Applications

Caliper Electrodes may be used for many electroporationapplications, including drug and gene delivery. The electrodes spanthe target area following injection of the molecule of interest,and electroporation pulses are delivered using a BTXElectroporation System, such as the ECM 600, ECM 630, ECM 830, ECM2001, or T820. The electric field introduced by the CaliperElectrodes cause transient pores to form in the cells of thetissue, allowing uptake of the molecules into the cells.Prud''Homme et al. used the Caliper electrodes to deliver plasmidDNA to skin for gene therapy studies on diabetes.1 Mir et al. usedthe Caliper Electrode for in vivo skeletal muscle work2 as well assubcutaneous tumor electrochemotherapy applications3. CaliperElectrodes can potentially be used for intact plant work aswell.4

Caliper Electrodes complement BTX Tweezertrodes Model 520, 522; BTXGenetrodes Model 508(S) and 510(S); and BTX 2 Needle ArrayElectrodes Model 530, 531, 532, 533 as part of the BTX in vivoelectrode line. Caliper Electrodes can be used to reproduceapplications requiring Tweezertrodes (transdermal) andGenetrodes/2-Needle.
