A Powerful & Versatile Gel Illuminator

Novel Laser Diode Illumination for Superior Performance

Gel illuminators have traditionally relied on UV illumination for visualization of fluorescently labeled nucleic acids and proteins. However, UV-based imaging can damage skin and eyes, as well as your DNA samples. LED-based illuminators were developed as a safer alternative to UV, but often have high background and dimmer signal due to excessive ambient light and poor excitation efficiency.

In partnership with Biotium, OMEC Medical has developed a new type of gel illuminator that uses laser diodes (LDs) optimized for brighter and clearer imaging of gels. The new laser diode-based Gel-Bright™ offers better sensitivity over UV-based transilluminators when imaging green dyes such as GelGreen® or SYBR® Green, as well as significantly better performance over blue LED gel illuminators for red dyes such as GelRed®, ethidium bromide (EtBr), and One-Step Lumitein™ Protein Gel Stain.

Gel-Bright™ Laser Diode Gel Illuminator – Each

Bright & Clear Imaging for Green or Red Dyes

GelGreen® (left) and GelRed® (right) stained DNA gels imaged with the Gel-Bright™ Laser Diode Gel Illuminator in the same field of view. The gels are a two-fold dilution series of Biotium’s Ready-to-Use 1 kb DNA Ladder (Cat. No. 31022) that were separated on 1% agarose TBE gels pre-cast with GelGreen® or GelRed®. From left to right, loading amounts were 200, 100, 50, or 25 ng/lane.

The Laser Diode Advantage:

  • Novel LD illumination: Superior performance for imaging fluorescent gels
  • Brighter signal: More sensitive than UV for green dyes
  • Versatile: Works well with both green and red dyes, unlike blue LED illuminators
  • Safer: Eliminates UV light hazards for user and DNA samples

Other Features:

  • Optimized lighting angle for even illumination
  • Adjustable light intensity
  • Multi-hinged adjustable amber filter for optimal signal
  • Easy access to the gel for gel slice excision
  • Compact and portable design


Superior Performance Over Blue LED Illuminators

Safe Imager™ vs. Gel-BrightLaser Diode Gel Illuminator

Comparison of Thermo Fisher Safe Imager™ 2.0 Blue-Light Transilluminator and Gel-Bright™ Laser Diode Gel Illuminator. An overview (top) is shown with the Safe Imager™ 2.0 Blue-Light Transilluminator (left) and Gel-Bright™ Laser Diode Gel Illuminator (right) in the same field of view, both with GelRed® (left) and GelGreen® (right) stained gels. The gels are a two-fold dilution series of Biotium’s Ready-to-Use 1 kb DNA Ladder (Cat. No. 31022) that were separated on 1% agarose TBE gels. From left to right, loading amounts were 25, 50, 100, or 200 ng/lane. The cyan (Safe Imager™) and green (Gel-Bright™) boxes indicate the field of view for the zoomed images of the gels shown below.

Sensitive Gel Imaging Without UV Hazards

Two-fold dilution series of Biotium’s Ready-to-Use 1 kb DNA Ladder (Cat. No. 31022) were separated on 1% agarose TBE gels pre-cast with GelRed® or GelGreen®. Total DNA loaded per lane is indicated below the gels. The same gels were imaged using a UVP GelDoc-iT® (UV), Thermo Fisher Safe Imager™ 2.0 Blue-Light Transilluminator (Safe Imager™), first generation Gel-Bright™ LED Gel Illuminator (Blue LED), or new Gel-Bright™ Laser Diode Gel Illuminator (Gel-Bright™). On GelDoc-iT®, an EtBr filter was used to image GelRed® and a SYBR® filter was used for GelGreen®. For imaging on Thermo Fisher Safe Imager™ 2.0 Blue-Light Transilluminator, Gel-Bright™ LED Gel Illuminator, and Gel-Bright™ Laser Diode Gel Illuminator, the filters supplied with each device were used to photograph both GelRed® and GelGreen® stained gels. The Gel-Bright™ Laser Diode Gel Illuminator demonstrated the brightest signal for gels stained with GelGreen® and performed comparably to the UVP GelDoc-iT® for gels stained with GelRed®.

Brightest Staining for Oxazole Gold (aka SYBR® Gold)

Two-fold dilution series of Biotium’s Ready-to-Use 1 kb DNA Ladder (Cat. No. 31022) were separated on 1% agarose TBE gels. Gels were then stained for 40 minutes with Oxazole Gold (aka SYBR® Gold). Total DNA loaded per lane is indicated. Gels were imaged using a UVP GelDoc-iT® (UV) and SYBR® Green filter or Thermo Fisher Safe Imager™ 2.0 Blue-Light Transilluminator (Safe Imager™), first generation Gel-Bright™ LED Gel Illuminator (Blue LED), or new Gel-Bright™ Laser Diode Gel Illuminator (Gel-Bright™) using the filters supplied with each device.

Compatible With Other Popular Dyes

Two-fold dilution series of Biotium’s Ready-to-Use 1 kb DNA Ladder (Cat. No. 31022) were separated on 1% agarose TBE gels pre-cast with ethidium bromide (left) or SYBR® Safe (right). Total DNA loaded per lane is indicated. Gels were imaged using a Gel-Bright™ Laser Diode Gel Illuminator.
