The Z125 GFP Closed FluorCam is designed for both chlorophyll fluorescence and other fluorescent protein imaging. The basic system of the Z100 FluorCam – Closed (CCD camera, four fixed LED panels) is supplemented here by a fully motorized and software-controlled filter wheel and appropriate filter sets for the detection and imaging of green fluorescent protein (GFP) in the standard system, red-shifted GFP, or yellow fluorescent protein (YFP) (optional). The blue emitting and red fluorescent protein can be detected and imaged in absence of chlorophyll. The device configuration also provides a user-friendly and quick transition between the GFP and chlorophyll fluorescence detection and imaging.
The Z125 GFP FluorCam – Closed System similarly to the Z100 FluorCam – Closed System consists of a high resolution and long integration time TOMI-2 CCD camera (1360×1024 pixels), 4 fixed LED panels that illuminate the sample, imaging software with protocols and 7 position filter wheel for imaging chlorophyll and GFP. Filters for other fluorescent proteins are optional. The LED panels provide uniform irradiance over samples up to 10 x 10 cm – suitable for small plants, detached leaves, petri plates with seedlings or algal cultures, etc. The system allows dark adaptation and includes a high-performance PC and a comprehensive software package for control of the system, data acquisition and analysis.
