Nikon AX R with Nikon Spatial Array ConfocalMicroscope System.

The National Institutes of Health (NIH), Office of the Director (OD) is conducting a market survey to determine the availability and technical capability of qualified small businesses, including 8(a) small businesses, small, disadvantaged businesses, woman-owned small businesses, service-disabled veteran-owned small businesses or HUBZone small businesses capable of providing a new Brand name or equal to Nikon AX R with Nikon Spatial Array Confocal (NSPARC) Microscope Detector Technology System.

Description:

Planned experiments involve ex vivo imaging of dissected mouse cochleae to study dendritic function and signaling in olivocochlear efferent neurons. Experiments will include calcium imaging, neurotransmitter imaging, genetically encoded voltage indicator imaging, and simultaneous patch-clamp electrophysiology. The neuronal dendrites under study are approximately 1 m in diameter, produce dim fluorescent signals, and require high-speed imaging with high signal-to-noise ratio.

The microscope system must provide enhanced fluorescence detection sensitivity to enable reliable detection of weak fluorescent signals while minimizing photobleaching and phototoxicity. The system must be configured as an upright microscope to accommodate ex vivo cochlear preparations, high-numerical-aperture water-dipping objectives, live pharmacological manipulations during experiments, and integration with patch-clamp electrophysiology equipment.
