產品規格

MyoStretcher 系統是高度客製化的,取決於各種研究應用。

Microscope

IonOptix-configured inverted microscopes provide an ideal platform for combined photometry and dimensioning measurements. These microscopes have been engineered to incorporate various unique IonOptix optical components and connectors in order to operate as the imaging component within our Calcium and Contractility Systems. Choose between the Motic AE31 or the Olympus IX73 depending on your application.

Light Sources

The fluorescence excitation light source is chosen with your specific research needs in mind and can be configured for almost any dye or combination of dyes. Options include the ultra-fast HyperSwitch, monochromatic LEDs, or the more affordable MuStep.

Sensors

The sensors within the Calcium and Contractility system are responsible for translating cellular signal into data. Cell contractility is measured using the high-speed MyoCam-S3 digital camera, and whole-cell fluorescence photometry is measured with a photomultiplier tube (PMT). For cleaner fluorescence signals, the Cell Framing Adapter allows you to frame a cell of interest and reduce background fluorescence.

Cell Stimulators

The field stimulator is an important component of excitation-contraction studies to provide acute stimulation of cells. Use either the MyoPacer for simple stimulation protocols or the MyoPacer EP for advanced sequencing and arrhythmic stimulation.

Fluorescence System Interface

The FSI ties the Calcium and Contractility system components together by communicating between hardware and the computer, allowing for synchronous control of contractility and/or calcium measurements as well as inputs and outputs for external devices.

Cell Chambers

Cells must be maintained in an appropriate chamber environment during experiments. For MyoStretcher systems, a rotational version of the FHD chamber is available that makes it easier to orient cells for mechanical loading.

Rail Configuration

 

For simple MyoStretcher configurations, an economical rail option is available that is compatible with most microscope types.

Stable Post Configeration

For experiments where stability is essential, such as work loops, the stable post configuration provides an extremely secure platform for your MyoStretcher measurements.

Optical Force Transducer

Designed as a core part of our MyoStretecher system, the IonOptix OptiForce is a revolutionary optical fiber interferometry-based force transducer specially designed to detect the nanoscopic forces from single isolated cardiac cells. It offers two major advantages over existing technologies: sensitivity and speed, with detection limits down in the low nanoNewtons and a frequency response above 3kHz.

Length Controller

With the piezoelectric motor for length control, you can specify cell length changes as percentage or absolute changes and use programmable wave to wave amplitude and duration changes to customize the stretch waveform.
