新型肌動圖仪 New Myograph Systems ------Living Systems Instrumentation
超级实惠的产品, 同样享受美国全进口产品的品质！
線性肌動圖 (Wire-Myograph) 通常被用於監測微小血管環 (血管內徑 60微米-3毫米)或肌肉條在藥物或電刺激下血管或肌肉張力的改變狀況(包括主動脈, 阻力微血管,氣管,支氣管 環、 肌肉、回腸和子宮肌條等). 肌動圖也可用於在監測血管張力和肌細胞張力的同時監測細胞膜電位的改變和組織螢光物質的測量. 肌動圖系統包括以下幾個部分:
•精工製作的在恆溫控制下的微小實驗小室；
•水平位的組織固定支架及其微細調控系統；
•精確的等張力傳感器和高度敏感的張力放大 系統；
•信號採集和計算機記錄,分析數椐硬體和軟 件系統。
The classic Halpern/Mulvany style wire myograph is back as a standard product available from Living Systems Instrumentation. Our MYO-CH wire myograph chamber is faithful to the basic design first introduced by Living Systems Instrumentation founder, the late Professor William Halpern, and Professor Michael Mulvany in their classic 1976 Nature paper titled “Mechanical properties of vascular smooth muscle cells in situ” (Nature 260(5552): 617-619, 1976). At the same time, state-of-the-art materials, machining, and force technology have been introduced. Our wire myographs include three types of tissue supports: wire-mounts for microvessels, L-bars for large ring preparations, and a hook for working with strips. Thus, our myograph is suitable for a range of applications including force measurements in microvessel rings, large vessels such as carotid artery and aorta, airway, intestine, bladder, and many more.
Features
- Modular tissue supports that allow use of wire-mount microvessel ring preparations, L-bars for working with larger ring preps, and a hook attachment for working with strip preparations.
- Convenient linear position controls in all three axes for the fixed tissue support. Force transducer support features smooth up-down position control, which simplifies alignments and initial slack adjustments.
- Small bath volume (~5 ml) and optional self-heating capability for efficient use of expensive peptides and reagents.
- Convenient integrated flow path helps achieve optimal flow pattern when bath superfusion is used.
- Glass coverslip chamber bottom facilitates tissue attachments, as the chamber can be illuminated from underneath. Also allows for simultaneous imaging-force studies.
- Precision force transducer capable of measuring forces from a few milligrams to 20 grams.
- Convenient analog signal output for easy data acquisition. (MYO-SC-1)
- Optional field stimulation electrodes available.

In some cases, such as when using expensive peptides or other drugs, bath superfusion is not an option. These applications call for minimizing the volume of bath fluid to keep the amount of reagents used to a minimum. In these cases, heating the bath to physiological temperatures can be problematic. However, with our wire myograph chamber (MYO-CH) and temperature controller (TC-09S), you can heat the wire myograph chamber directly to physiological temperatures. This package contains everything needed to conduct these self-heating studies in our wire myograph chamber.
