Recombinant Endotoxin Detection ReagentPYROSTAR™ Neo

  • Chromogenic Technique
  • Endotoxin Specific
  • Recombinant

PYROSTAR™ Neo is a new endotoxin detection reagent developed by recombinant technology.

PYROSTAR Neo is a lyophilized reagent that combines 3 recombinant factors (factor C, factor B, proclotting enzyme) with sequences derived from Limulus polyphemus and a chromogenic substrate (peptidyl pNA).
The PYROSTAR™ Neo is high sensitive with specific assay for endotoxin.


  • Since colorimetric method, the same colorimetric plate reader can be used.
  • Same cascade reaction as Lysate reagent, conforms to traditional detection.
  • Endotoxin specific reagent, no false positive risk of (1→3)-β-D-glucan.
  • Quantification of endotoxin with a wide range of 0.001 to 50 EU / mL and high sensitivity
  • Could be stored at 2-8℃ about 4H after solution/at -30 degree for about 2 weeks. Reagent waste is reduced.
