Storm 860 Molecular Imager
Storm 860 Gel and
Blot Imaging System offers filmless autoradiography, fluorescence
and chemifluorescence imaging.
Storm Gel and Blot Imaging System delivers proven PhosphorImager
capability for autoradiography, direct fluorescence for nucleic acid
and protein gel analysis, and chemifluorescence for fast blot
analysis. Storm uses storage phosphor screens instead of film to
deliver high-resolution imaging and accurate quantification of
14C, 3H, 125I, 32P, 33P,
35S, and other sources of ionizing radiation. The
system’s wide exposure range and accurate signal quantification
yield publication-quality images on the first exposure. Storage
phosphor screens are reusable and are not degraded by repeated
exposure to laboratory levels of radioactivity. To reuse, simply
expose a screen to the extra-bright light of ImageEraser light box
(included with Storm systems). With direct fluorescence, Storm
enables visualization and analysis of nucleic acid and protein gels
just minutes after electrophoresis is complete. Gels are soaked in
dye solution and then placed in the scanner for analysis. Molecules
labelled with Cy5 can also be directly detected.
For chemifluorescence-based methods, Storm reads blots in minutes,
without exposure to film. Quantification is simplified because,
unlike film, Storm exhibits a linear response to fluorescent signal
intensities.
Storm scans gels, blots, or mounted and unmounted storage phosphor
screens up to 35 × 43 cm. All Storm systems come with ImageQuant™
TL.
The
STORM 860 phosphorimager/fluorimager has three image detection
modes:
 |
Phosphor Screen Mode |
|
|
Red/Blue Fluorescence |
|
|
Chemifluorescence |
You can use screens for 14C, 32P, 33P, 35S, and 1251;
and 3H sensitive screens can also be purchased.
The STORM is also a two-color (blue and red
excitation) fluorescence imager, which opens up many new
possibilities for quantitative analyses:
|
|
Quantitative westerns by chemifluorescence |
|
|
Nonradioactive gel mobility shift experiments,
in which two different species can both be separately detected
and quantified. |
|
|
Fluorescent dyes for quantitative versions of
coomassie staining |
