MappingLab Ltd offers standard OMS-PCIE-1001, OMS-PCIE-1002 and OMS-PCIE-2002 systems as well as customized systems. Dual signal optical mapping systems are suitable for simultaneous recording of cardiac membrane potential and calcium imaging. Our latest optical mapping system is equipped with back-illuminated scientific CMOS cameras with 95% quantum efficiency (QE) and pixel size from 6.5 μm x 6.5 μm to 11 μm x 11 μm. It provides high-speed, low-noise acquisition with a dynamic range of up to 50,000:1 (94 dB). The optical axis can be either vertical or horizontal. There are various I/O connectors to help researchers set up the communication system. An 8-channel TTL controller is designed to synchronize devices such as camera, LED light controller, stimulator, ECG, MAP, pressure and temperature probes with the optical mapping system. OMapRecord/Scope is an advanced data acquisition and analysis software with a user-friendly intuitive interface and highly efficient data management.
Software.
OMapRecord can simultaneously record a variety of fluorescence signals, including membrane potential and calcium transient. It can also record ECG and pressure at the same. OMapScope is a powerful analysis software with a user-friendly interface, which can compute many important and meaning parameters, such as conduction velocity, conduction dispersion, AP triangulation, APD, and phase mapping.
Hardware.
OMS-PCIE-1001 and OMS-PCIE-1002 have a CMOS camera built in. The difference between them is that the former can only acquire a single fluorescence signal, i.e. calcium or membrane potential, while the latter can acquire two fluorescence signals simultaneously. However, OMS-PCIE-2002 has two CMOS cameras in the system to acquire calcium and membrane potential simultaneously. In principle, OMS-PCIE-2002 is the better choice for dual signal recording due to higher resolution and less signal attenuation.
