WESTAR ECL Substrates for Western Blotting — Two-Component Chemiluminescent Substrate Family

What is WESTAR?

WESTAR is Cyanagen’s comprehensive family of two-component chemiluminescent (ECL) substrates for Western blotting, designed to deliver outstanding performance across a wide range of experimental applications. Offering multiple sensitivity levels, the WESTAR portfolio enables protein detection from the picogram down to the attogram range, providing the flexibility required for both routine and highly demanding analyses.

Among the flagship products, WESTAR ANTARES and WESTAR ETA C ULTRA 2.0 stand out for their exceptionally long-lasting signal of up to 20 hours, ensuring greater flexibility during image acquisition and enhanced reproducibility of results. For researchers seeking the ultimate sensitivity, WESTAR HYPERNOVA incorporates Cyanagen’s exclusive patented technology to achieve attogram-level detection, surpassing the performance of leading premium substrates on the market.

Powered by proprietary signal-enhancement chemistry, WESTAR enables precise tuning of signal intensity and duration, allowing researchers to achieve the optimal balance among sensitivity, stability, and performance. The result is a versatile product range that meets the specific requirements of any Western blotting workflow.

Why Choose the WESTAR Family

 

A Complete Sensitivity Spectrum in One Family

The WESTAR portfolio spans the full sensitivity spectrum needed for Western blotting, from mid-picogram detection with WESTAR SUN and NOVA 2.0, through mid- and low-femtogram performance with WESTAR ANTARES, ETA C ULTRA 2.0, and SUPERNOVA, up to attogram-level detection with WESTAR HYPERNOVA. This means a single substrate family can support every stage of a research workflow, from routine screening to the most demanding low-abundance protein detection.

 

Exceptionally Long-Lasting Signal

WESTAR ANTARES and WESTAR ETA C ULTRA 2.0 stand out for signal duration of up to 20 hours or more, giving researchers greater flexibility during image acquisition, the ability to perform repeated exposures, and improved reproducibility of results.

 

Patented Technology for Ultimate Sensitivity

WESTAR HYPERNOVA incorporates Cyanagen’s exclusive patented technology to achieve attogram-level detection, surpassing the performance of leading premium substrates currently on the market.

 

Precise Tuning of Signal Intensity and Duration

Powered by proprietary signal-enhancement chemistry, every WESTAR substrate allows precise tuning of signal intensity and duration, helping researchers achieve the optimal balance between sensitivity, stability, and performance for their specific workflow.

 

Universal Compatibility

All WESTAR substrates are compatible with every major chemiluminescence imager and X-ray film detection system, and are well-suited to different membrane types, blocking reagents, and a wide range of antibody dilutions — all while maintaining low background and a high signal-to-noise ratio.

WESTAR is Cyanagen’s family of two-component chemiluminescent (ECL) substrates for Western blotting, covering detection levels from mid-picogram to attogram to suit both routine and highly demanding applications.

WESTAR SUN and WESTAR NOVA 2.0 are designed for routine applications, offering mid-picogram and low-picogram sensitivity, respectively, at an excellent performance-to-price ratio.

WESTAR ETA C ULTRA 2.0 offers a signal duration of more than 20 hours, closely followed by WESTAR ANTARES at up to 20 hours — both ideal when imaging flexibility and repeated exposures are required.

WESTAR HYPERNOVA offers the highest sensitivity in the family, achieving attogram-level detection thanks to Cyanagen’s exclusive patented technology.

WESTAR SUPERNOVA delivers low-femtogram, top-level detection with signal duration up to 11 hours. At the same time, WESTAR HYPERNOVA goes further to attogram-level detection with a shorter 5-hour signal duration, designed for the most extreme sensitivity requirements.

Yes. All WESTAR substrates are compatible with chemiluminescence imagers and X-ray film detection, and work with a wide range of membranes, blocking reagents, and antibody dilutions.

The WESTAR range covers mid-picogram (SUN), low-picogram (NOVA 2.0), mid-femtogram (ANTARES), mid- to low-femtogram (ETA C ULTRA 2.0), low-femtogram (SUPERNOVA), and attogram (HYPERNOVA) detection levels.
