资料摘要：

Harness tethers, first developed by Instech in collaboration with Danny Jack at Covance Laboratories in 1997, are made of a soft elastomer saddle with a vented dome that protects the catheter exit site, ad - justable belly bands to secure the saddle to the ani mal, and a stainless steel spring to protect the fluid line and transmit torque to a swivel. Vascular Access Harness? for Rats The VAH? system permits quick and aseptic connection and disconnection of a catheterized rat and an infusion tether. Instech’s VAH is currently the most popular method tethering a rat for infusion or sampling. The system consists of a small external port housed in a harness which is installed at the same time that the catheter is implanted. The catheter is attached to a connector built into the port under the harness dome and then the port and catheter are filled with lock solution to maintain patency during transport. Access the harness manually to sample, dose or check patency using a syringe with a VAH6M injector with needlestick protection. To begin a continuous infusion or blood sampling study simply plug a mating VAH tether into the harness. A recessed needle built into the tether makes the fluid connection through the port. The VAH is a closed system: tether connection does not introduce contamination or air. Furthermore, retrograde flow, which can lead to occluded catheters, is virtually eliminated.

斑马鱼显微注射是将实验材料直接注射到1-4细胞期的斑马鱼胚胎中，由于在这个胚胎发育早期没有膜分隔细胞和卵黄，注入1个细胞或卵黄的溶液将扩散到整个胚胎中。通过注射不同类型的实验样品，实现基因的瞬时过表达（over-expression）、表达敲减（knock-down）、以及制备转基因或突变斑马鱼品系等研究。

桌式麻醉机使用说明

吸入式气体麻醉，是在供给动物的气流中添加入麻醉气体（浓度受麻醉挥发罐的精确控制，且可随动物生理状况实时调节），以此对动物进行麻醉。在维持麻醉过程前，需要以高麻醉浓度、大流量的气流对动物进行诱导麻醉，方便对动物进行固定处理等术前准备。麻醉尾气需通入活性炭盒（F/AIR）进行吸收处理，以消除其对实验人员的影响。

脑立体定位仪的使用方法

脑立体定位仪是利用颅骨外面的标志或其他参考点所规定的三维坐标系统来确定皮层下某些神经结构的位置，以便在非直视暴露下对其进行定向的刺激、破坏、注射药物或引导电位等操作。它是神经解剖、神经生理、神经药理和神经外科等领域内重要的研究设备，可用于帕金森氏病动物模型的建立、电线动物模型的建立、脑内肿瘤动物模型的建立、学习记忆、神经干细胞移植、脑缺血等研究。

Mixture/Dose Delivery System

The PHD ULTRA? Gradient Systems allows you to quickly and easily run binary or ternary mixtures automatically without a PC. The Method is totally programmed from a master controller pump, for easy set-up. The intuitive program interface makes simple to complex mixing easy. The Gradient Profile is used to combine multiple flow streams from different pumps into a common output stream. The flow can be smooth and continuous or stepped. No stopping the experiment, mixing different % volume mixtures and placing new syringes into the pumps. Push one button and it all happens automatically. Binary and ternary gradient systems are available with or without a stand. Individual Satellite units are also available for purchase separately. For more information on the PHD ULTRA? Syringe Pumps see page 18-22. For more information on the PHD ULTRA? Satellite units see page 21.
