The Gemini EM spectrofluorometer allows
for fast, high-sensitivity measurements. Cellular and molecular
binding studies, DNA quantitation, drug screening, and SNP
genotyping analysis all require a high degree of sensitivity. The
Gemini system offers a flexible, filter-free environment
allowing the determination of optimal excitation and emission
settings in 1.0 nm increments providing the best level of
sensitivity for variable assay conditions. |

Features

|
Top and Bottom Reading Optics-The
top/bottom reading optical design of the Gemini EM allows for
measurements for both solution and cell-based assays. |
| |
|
Dual
Monochromators — The right pair
of excitation and emission wavelengths is always available
because the dual monochromators allow the selection of any
wavelength in 1 nm increments. New fluorophores can easily be
evaluated without purchasing additional filters. |
| |
|
Wavelength
Scanning — The most sensitive
results are achieved by using optimal excitation and emission
wavelengths. Literature wavelengths are often based on results
from wavelength-limited, filter-based readers. Wavelength
scanning ensures that the most sensitive assay conditions are
used. |
| |
|
Well
Scanning — Gemini EM can report
a single point from the well center, or multiple data points
from large well tissue culture plates. This provides high
sensitivity for cell-based assays. |
| |
|
Auto PMT
Gain — Because a single
microplate often presents a range of fluorescence intensities
greater than three orders of magnitude, Gemini EM features
“Auto PMT Gain” to avoid saturating the photomultiplier tube.
The signal is calibrated against an internal standard, so the
reported RFU values of individual samples can be accurately
compared. |

SoftMax Pro software
SoftMax Pro allows you to select
excitation and emission values and simply input their values for
the monochromator settings. You can easily scan both excitation
and emission spectra and determine the optimal settings.
Software not included.
Engineered for superior performance and reliability
Gemini EM dual monochromator design —
an excitation monochromator (A) and emission monochromator (B) —
allows user-defined variable wavelength settings. Sending light
through a movable scanning grating (D) which selects the desired
excitation wavelength. The light is passed through 1 mm fiber
optic bundles (E) to elliptical focusing mirrors (F) that maximize
light collection efficiency for superior sensitivity and send the
beam to a microplate well (G). If fluorescent molecules are
present, the light of the emission wavelength is emitted back out
to focusing mirrors (H) that direct the light through 4 mm fiber
optic bundles (J) to the emission scanning grating (K). The
desired wavelength of light is then detected by the
photomultiplier tube, or PMT (L). The PMT passes the fluorescence
signal through the Gemini’s electronics, creating the signals that
result in data points collected by software. |
