Luminometer for 96/384 well plate
AB-2350 PHELIOS
The development history for ATTO's luminometer was started
from 1980 with luminescent detector for HPLC. Since then we
have been developed measurement methods for biological activities of living cells and tissues by bioluminescence and chemiluminescence, and finally we commercialized microtiter plate reader
"Luminescencer" for automatic luminescence measurement in
1991.
Afterwords, ATTO released "Luminescencer JNR" as a luminometer for microtiter plate in 1997, and followed by releasing
"Luminescencer PSN" as a luminometer for microtubes. Thus we
have been consistently producing for various product range as a
specialized manufacturer for luminescence .
Furthermore, ATTO has made efforts to develop basic technologies such as bioluminescent imaging system, active oxygen
measurement system, multi-color separation system, luminescent spectrophotometer, novel secretory luciferase (Cluc), and
also studied the mechanism of firefly luciferase reaction, global
standardization of luminescent measurement, and near infrared
measurement technology.
"ATTO Phelios" offers superior performance for measuring bioluminescence and chemiluminescence in flash and glow assays
with high sensitivity and reliability, and it is useful tool for diverse
applications from ELISA to cell based assays.
ATTO Luminometers Application Data
Measurement of Anti-oxidant activity
Anti-oxidant activities of food ingredients (substances) can be compared using bio-luminescent agents (such as MCLA, MPEC, NIRCLA,,,) that reacts against ROS(Reactive Oxygen Species). Anti-oxidant activities can culculate from the ratio of bioluminescent
intensities between samples with and without ROS inducer. Generally, the anti-oxidant activity is evaluated by the concentration of
anti-oxidant substance which is reached to 50% of maximum bio-luminescent intensity, and this concentration is commonly compared with the concentration of water soluble vitamin E.

[Method]
The measurement of anti-oxidant activities in vitamin samples were carried out using Phelios (AB-2970) and CRETA-S. The concentration of vitamin C was prepared from 40μM to 100mM, and the concentration of the vitamin C which is reached to 50% of the
relative luminescent intensity was examined. As a result, the bio-luminescent intensity was reached to 50% when the concentration of vitamin C was about 1mM.
Triple Reporter Assay
The result shows the bio-luminescent intensities of tri-color luciferases in NIH3T3 cells measured by using Phelios. The bioluminescent
intensities are in proportion to the amounts of transfected DNA, since Phelios enables to measure and analyze individual colors of luciferases in single cell.
[Method]
NIH3T3 cells were transfected the control vectors (Tripluc) , pSLG-SV40 control, pSLO-SV40 control and pSLR-SV40 control (purchased
from TOYOBO, JAPAN) with lipofection method. Next day, the medium is changed to the fresh one including 0.2mM of luciferin, and
measured accumulated bioluminescence intensities for 10sec. using F0, F1 and F2 filters with Phelios.
Application Data
Luciferase Assay
Phelios enables to detect at least 1zmoles(10-21 moles) of
luciferase molecules. Phelios can be useful for quantitative
measurement of widely concentrated sample in linearity dynamic rage (log 7).
[Method]
Set the 96 well black plate onto the plate holder of Phelios
that added 20μL of luciferase diluted solution (Triplet) in each
well. It measured bioluminescence accumulated from 2sec
and 10sec after auto injection with 80μL of luciferin by injecApplication Data
ATP Assay
Phelios enables to detect up to 1 amoles (10-18 moles) of ATP
molecules, over more linearity dynamic range shows quantitative
measurement in wide concentration samples up to log 8.
[Method]
Ten mL of ATP diluted solution was added in each well of a 96
well black plate, and set it onto the plate holder of Phelios. It
measured accumulated bioluminescence intensity from 2sec to
10sec after auto injection with 90μL of luciferase-substrate reagents for ATP detection.
Autophagy
The studies related autophagy such as oxidative stress of
mitochondria and PKC signal pathway has been progressing.
It is available to observe intracellular changes in the amounts
of active oxygen generation for long time (~1h) by Phelios.
[Method]
HL60 cells (1.8 x 105) were added 100 ng of PMA, and the
changes of generation amounts of active oxygen was detected with MCLA (Bioluminescent reagent). It reveals that active
oxygen was generated by PMA stimulation, since relative bioluminescence intensity should decrease by SOD addition.
High-sensitivity Immunoassay
Interferon alpha was detected by sandwich immunoassay method (CLEIA) with Biotin-labeled anti-INF alpha antibody and
Cypridina luciferase labeled streptavidine. The result showed at
least 10pg/mL of INF alpha could be detected with Phelios.

High Sensitive & Versatile Luminometer Phelios
Introduction
AB-2350 Phelios is a microplate luminometer developed to intend to measure multi samples with
the highest efficiency of light detection. Phelios is available to measure diverse wavelength of bioluminescence from 350 to 670nm in 96, 384 well microplate. It achieves highly sensitive detection with added and extremely desired optical system for efficiency of luminescence by the technology of low noise photon counting. Besides, it accomplishes high reproducible measurement by
internal temperature controller and highly accurate pump in repeated injection. Moreover, even in
case of different multi-colors luminescent generation, it is available to measure the samples respectively by dedicated automatic filtering function.

Basic Specification
Reproducibility
The reproducibility of Phelios was confirmed by repeated
measuring the light intensity of green LED of standard light
source TRIANT for 5seconds. The result showed high reproducibility with low CV value of around 0.21%. The background
value was around 10 counts/sec.
Linearity
Light intensities of green LED as a standard light source were
measured for 5 seconds. As a result, stable linearity was
shown in the range from 1 to 10000 light units (light quantity
of TRIANT ).
Injector pump
The injector pump equipped in Phelios is high accurate for repeated injection and
optimizing flow rate. The pump demonstrated CV values of 0.05% in 10 times of
250μL injection test, and 0.5% in 10 times of 30μL injection test. It reveals high accuracy in each injection test. To confirm the imperative injection speed, the reaction
of Aequorin and Ca2+ ion which is usually in second was analyzed with Phelios. After
injection of Ca2+ ion with injector pump, bioluminescence of Aequorin generated
immediately and reached the maximum light intensity, and then it eventually deminished gradually. The pump is also suitable for high performance even for flash bioluminescence.
PMT sensitivity
The PMT (photomultiplier tube) equipped in Phelios is
adapted through severe inspection test for the lowest noise
and high efficiency in long wavelength. ATTO also has the
device for near infrared detection. Please feel free to ask us.
Automatic multi-color filtering system
Phelios installed automatic multi-color filtering system which
can distinguish up to 3 different colors luciferases by two
different filters. By this technology and Tripluc (TOYOBO), it
accomplishes analysis of three different genes expression
with one substrate.
