The iBright 1500 Series Imaging Systems were designed to make western blot and gel imaging easy. Click on each subtopic below to learn more.


The core applications you need and the specialty applications you want

The iBright 1500 Series Imaging Systems offer up to five imaging modes to support your multiple applications. Efficiently and easily capture data from protein gels, nucleic acid gels, chemiluminescent western blots, fluorescent western blots, and more.

Image mode What kind of signal can be captured?
Protein gel Colorimetric staining of gels (e.g., Coomassie, silver) and membranes (e.g., Ponceau S, Thermo Scientific Pierce Reversible Protein Stain), fluorescent staining of gels (e.g., Invitrogen SYPRO Ruby stain)
Nucleic acid gel Ethidium bromide and Invitrogen SYBR stains
Chemiluminescent blot Chemiluminescence using all popular HRP and AP substrates (e.g., Thermo Scientific SuperSignal and Invitrogen WesternBreeze substrates)
Fluorescent blot Fluorescence with popular RGB (visible range) and near-IR fluorophores (e.g., Invitrogen Alexa Fluor and Alexa Fluor Plus conjugates)
Universal Custom mode to image samples containing multiple signals, such as chemiluminescence, fluorescence, colorimetric stains, and/or visible images; image display is similar to fluorescent blot mode and allows one to assign false color to any sample

Load and go—Our 12.1 inch LCD touchscreen interface has a simple, logical layout of functions and features, making our systems easy to use with minimal training. Workflows are similar between imaging modes—for a smooth imaging experience regardless of sample type.

9.1 MP camera

Get publication-quality data fast


Capture crisp, clear, publication-quality images with a 9.1 megapixel cooled CCD camera.

Smart Exposure technology rapidly determines optimal exposure time, minimizing the potential for over- or underexposed images and the need to repeat exposures to get the desired signal.

Automated features

Rather than having to open the sample drawer and repeatedly reposition your sample to achieve proper alignment, iBright 1500 Series Imaging Systems automatically determine the sample position and can rotate samples left or right up to 10° on a mechanically rotating sample stage. Mechanical rotation eliminates the need to digitally rotate the sample, which preserves the integrity of the data, as digital rotation can lead to data alterations.

Zoom function

Digital rotation vs. mechanical rotation. (A) Pixels rotate with digital rotation so bands appear jagged. With mechanical rotation, the sample itself rotates, so bands remain smooth in appearance as the pixels remain aligned. (B) Graphic depicting iBright Imaging System sample stage before and after rotation.

In addition, iBright 1500 Series Imaging Systems automatically determine if the sample requires zoom in order to maximally utilize the 22.5 cm x 18.0 cm field of view. If imaging a single blot, the camera will mechanically move toward the sample up to 2X zoom (8X with additional digital zoom). Mechanical zoom maximizes sensitivity by moving the camera closer to the sample stage and thus reducing focal length. iBright 1500 Series Imaging Systems automatically adjust focus for each level of zoom, producing A crystal-clear images.

Field of view

Big field of view, small footprint—The iBright Imaging Systems feature a light path design that helps enable a large functional viewing area in a relatively small instrument footprint (68 x 38 x 60cm).

Field of view
The large field of view (22.5 x 18.0 cm) enables capture of up to 4 mini blots or gels.

Filter sets

Accelerate your research—The iBright FL1500 model features five fluorescence channels, permitting up to 4-color fluorescent western blot multiplexing and expanding your possibilities for studying multiple proteins in a single blot. Obtain meaningful and representative comparisons to enhance your experiments. Smart Exposure technology further improves acquisition of multiplex fluorescent western blot data, because signal-to-noise ratios are optimized for each fluorescent channel separately.

Filter sets pre-installed in iBright FL1500 Imaging Systems for visible light range (RGB) and near infrared range (NIR) fluorescent western blotting applications.

Green-LED transilluminator

Green-LED transilluminator

Go-Green:The iBright Imaging Systems utilize a transilluminator based on green LEDs, which effectively excite popular DNA dyes such ethidium bromide and SYBR Green dye and offer many additional benefits.

No harmful UV rays

No harmful UV rays: While UV light effectively excites many fluorescent dyes and stains, UV light is a health hazard. Further, prolonged exposure to UV light can damage DNA samples, and compromise the integrity of samples to be used for downstream applications, such as subcloning.

No mercury waste

No mercury waste: UV transilluminator bulbs contain mercury, a hazardous substance, and therefore require special care for handling and disposal.

Longer lifetime

Longer lifetime: LED bulbs have a substantially longer real-time life than UV bulbs, which can add up to considerable cost savings over the lifetime of the instrument.
