WESTAR is Cyanagen’s patented product line dedicated to Western Blotting

  • WESTAR SUN – standard signal intensity
  • WESTAR NOVA 2.0 – medium signal intensity
  • WESTAR ETA C 2.0 – high signal intensity
  • WESTAR ETA C ULTRA 2.0 – very high signal intensity
  • WESTAR SUPERNOVA – extreme signal intensity

Westar products cover a wide range of possible signal intensity and duration, from the entry level ECL-SUN, to the top of the line, SUPERNOVA. Each product is at the top of its market segment for performance, and cost to performance ratio.


WESTAR detection reagents are non-isotopic, luminol-based chemiluminescence substrate, designed for the chemiluminescent detection of immobilized proteins and immobilized nucleic acids conjugated with horseradish peroxidase (HRP). Using this method, it is possible to detect membrane immobilized specific antigens, or sequences of nucleic acids, labeled directly with HRP or indirectly with HRP-labeled antibodies/streptavidin.

Figure 1. WESTAR for Western blot.

WESTAR substrates for HRP detection of CYANAGEN are a powerful tool for studying low expressed protein, up to a detection limit of few femtograms. The higher and steadier light emission produced by these second generation of chemiluminescent substrates also give the possibility of using lower amounts of precious antibodies (primary and secondary), greatly reducing the cost for Western blot assay (see figure 2).

Human Transferrin diluted (5 to 0.5ng) and electrophoresis performed. The gels were transferred to PVDF membranes, blocked and incubated with different dilutions of rabbit anti-transferrin. After washing, the membranes were incubated with different dilutions of HRP-conjugated goat anti-rabbit antibody. The membranes were washed again and then incubated with substrate. Blots were acquired with ImageQuant LAS 4000 (GEHC) for 300 sec.

Elisa substrates icon

ELISTAR is the Cyanagen’s NEW patented product line dedicated to ELISA.


ELISTAR products offer the best performance in their market segment and are powerful tools in diagnostic research and food analysis.


Protein Quantitation

Cyanagen’s Protein Quantitation line includes Qpro and mQpro.
They are Bicinchoninic Acid (BCA) - based protein assay (BCA assay) for highly sensitive colorimetric analysis, compatible with detergent solubilized protein solutions.
The BCA method is fast and easy, providing enhanced flexibility with much greater tolerance to interferences by non-ionic detergents and buffer salts.


  • Broad linear working ranges with excellent sensitivity
  • Can be used with tubes and microplates
  • Less protein-to-protein variation than dye-binding methods
  • Unaffected by most ionic and nonionic detergents such as Triton-100 and SDS (1%)
  • Much easier and faster than the classical Lowry method

Fluorescent in-gel protein stainFluorescent Gel staining icon

Ruby Gel Stain is a ready to use kit for rapid and sensitive protein staining in 1D and 2D SDS polyacrylamide electrophoresis gels.
It enables optimal visualization and quantitation of proteins with high contrast and the same sensitivity as silver staining without its drawbacks. The staining procedure is a simple 220 minutes, three step protocol.
After staining, proteins can be removed from the gel and analyzed by mass spectrometry without interference from the stain.
The dye has optimal excitation at 302 and 470 nm, with an emission maximum at approximately 610 nm. Ruby Gel Stain can be excited with UV-light, UV transilluminator and 405, 445, 473-488 nm laser sources.


  • Ready to use kit
  • High purity dye: >98%
  • Optimal signal to background ratio
  • Strong, uniform and reproducible signal from 0.2 ng to 10 ng protein
  • Fast staining protocol (220 min)
  • Convenient: fixing and destaining solutions included in the kit

The gel can be visualized using excitation wavelength in the 400-500 nm range with bright emission peak centred around 610 nm.

Green nucleic acid stain  



Green Stain


Fluorescent dyes iconGreen Stain is a versatile and easy to use tool for the detection of nucleic acids (dsDNA, ssDNA, RNA) in electrophoretic gels. Bright green fluorescent bands and very low background fluorescence are its major features, together with high sensitivity and very low toxicity.
The nucleic acid-bound Green Stain is efficiently excited at ~254 nm and ~488 nm; it can also be excited at ~312 nm with loss of sensitivity. Detection can be performed with the same instruments used for ethidium bromide and SYBR® Green gel staining such as standard UV transilluminator (254 nm) as well as with CCD-camera imaging system or laser-based scanner selecting the SYBR® Green filter.

Sufficient for:

0.5 ml is sufficient for 50 minigels stain


10000X Solution in DMSO




Cyanagen has developed a new fluorescent dye for the detection of nucleic acids: Green Stain (10000X in DMSO).
Green Stain is a versatile and easy to use tool for the detection of nucleic acids (dsDNA, ssDNA, RNA) in electrophoretic gels, based on pre-electrophoresis gel staining, sample pre-staining and post-electrophoresis gel staining.
Excitation/emission spectra of Green Stain bound to dsDNA
Excitation/emission spectra of Green Stain bound to dsDNA


  • Sensitivity: Detection as little as 100 pg dsDNA per band.
  • High contrast: Bright green fluorescence with exceptionally low background.
  • Safe: Very low toxicity.
  • Easy to use: Substitute your reagent with Green Stain using one of the following protocols:
    - pre-electrophoresis gel staining for the highest sensitivity
    - sample pre-staining for the best migration results
    - post-electrophoresis gel staining for particular protocol needs
