此电极是设计用于原位贴壁细胞的电穿孔或在除样品杯以外的其他容器内进行较大量的电穿孔操作，使用电极在原位对贴壁细胞进行电穿孔避免了需使用化学品消化细胞以及低穿孔效率，中断了细胞周期及细胞间的联系等诸多问题，应用于哺乳动物细胞转染，基因**，蛋白或**的传递，也可应用于植物和酵母。
此电极是一种可复用的电极，适用于配装于6孔板的每个单孔或一个35mm直径的培养皿，由13个间隔2mm的镀金电极组成，适用于BTX各型电穿孔仪。
The Petri Pulser™ PP35-2P is a reusable electroporation applicator designed to fit into each single well of a 6-well plate or an individual 35mm diameter petri dish. The PP35-2P consists of an electrode assembly embedded in a polyurethane holder with high voltage electrode cables. The thin electrodes are gold plated and designed to maximize the surface area of electroporation. The high voltage cables are connected with a BTX Pulse Generator, and the electrode head inserted into the dish or well containing the sample. An electroporation pulse may then be delivered. The entire applicator may be cleaned with mild detergent, and the electrodes may be sterilized with ethanol and dried with acetone.
Applications
General Applications
The Petri Pulser PP35-2P is designed for the electroporation of adherent cells in situ or as an alternative to cuvette electroporation for larger volumes or multiple cell samples. The use of the electrode for the electroporation of adherent cells in situ eliminates the need for trypsinization or mechanical removal of cells from their growth substrate. This eliminates associated problems including low plating efficiencies following electroporation, interruption of cell cycle and interruption of intercellular communication.
Mammalian Cell Protein/Drug Electroincorporation
The Petri Pulser PP35-2P supplements our Model 366 Petri Dish Electrode designed for 100 mm petri dishes, as the ideal electrode for in situ electroincorporation of protein into mammalian cells.1,2,3 This electrode has been used for electroincorporation of peptides and proteins in CHO cells4 and vascular smooth muscle cells5.
Mammalian Cell Transfections/Gene Therapy
The Petri Pulser PP35-2P is capable of supporting transfection protocols developed for our larger Model 366 Petri Dish Electrode, including protocols for BHK and HUVEC.6 The electrode itself has been used for the transfection of 3T3-L1, Rat adipose cells, SF295 human neuroglioblastoma and Cos 7 cells.7
