Experiment Details

FLI Specificity Experiment:

NIRF probe: OsteosenseTM 680; targets hydroxyapatite in growth plates of long bones

Probe max Ex/Em = 668/687 nm

Test Mice (n=2): 100uL Osteosense™680, IP

Control mice (n=2): 100 uL PBS, IP

All mice imaged 24 hrs post IP injection

Orientation during imaging: Mice 1, 3: dorsal  | Mice 2, 4: ventral

The physics behind the data:

LED spectrums are inherently narrow and specific – falling within the 20 nm filter bandwidth

White light has a broad emission and relies on filters to limit 93.5% of light. Out-of-band photons result from the physical limitations of filters blocking excessive light.

Out-of-band, excitation-based light is detected across a range of Em filters in white light based competitors. This non-specific, out-of-band light, reflects off mice, reducing Signal/Noise ratio.

High Sensitivity + Low Background = Accurate Quantification

Individually controlled LED’s allow you to avoid overlapping fluorescent spectra entirely – providing clean, multiplex fluorescent data.

Continuous light from white tungsten bulb requires software algorithms to artificially separate spectra.

Imagine the Possibilities

Experts trust Experts

Spectral Instruments Imaging is the fusion of principal developers in in vivo imaging technology and a world class camera manufacturer. Working together to advance pre-clinical imaging to reveal complex biological processes.

What researchers are saying...

We were so pleased with the instrument’s performance and SII’s support within the very first year of use that we committed to a replacement of our entire suite of older instruments with SII products.

The LED based illumination meant that there was nearly a 90X more light incident on the surface of the specimen versus traditional white lights used by other manufacturers which translates to earlier detection – sometimes weeks ahead – saving researchers time and money. It also dramatically improved the utilization of the imaging core.

SII has a single-minded focus on building the best optical imaging instruments for bioluminescence and fluorescence. The entire company – management, engineers, sales team and support is aligned around that central focus.

This has meant many good things for us as a customer – where the innovation continues non-stop. We are already seeing many new features in software and hardware that leave us very optimistic about the future.
