Venus 96E Pro for Quantitative LAL Assays

Venus 96E Pro
  • rCR (Recombinant Cascade Reagent) – The Closest Mimic to Traditional LAL
  • rCR reagents contain three recombinant proteins: Factor C, Factor B, and proclotting enzyme. This recreates the full enzymatic cascade of natural LAL/TAL for kinetic chromogenic detection.

Key Features:

  • Kinetic chromogenic method (absorbance at 405 nm) — same as your existing LAL protocols.
  • Compatible with standard incubating microplate readers and software (no new capital investment).
  • High sensitivity (typically 0.005 EU/mL or better).
  • Real-time kinetic monitoring for quantitative results.

Strengths:

  • Seamless transition from LAL workflows.
  • Full cascade amplification for robust signal.
  • No β-glucan false positives.
  • Reduced lot-to-lot variability compared to natural LAL.
  • Excellent performance in complex matrices.

Considerations:

  • Product-specific verification under USP <86>.
  • Ideal For: Labs wanting minimal method change while going fully animal-free. Perfect for pharma water testing, parenterals, biologics, and medical devices.

COMMON APPLICATIONS

  • Pharmaceutical Products
    Endotoxin testing for injectables, APIs and finished products.

  • Water Systems
    Purified Water (PW) and Water for Injection (WFI) monitoring.

  • Medical Devices
    Testing of devices and components for endotoxin contamination.

  • Biologics
    Suitable for proteins, vaccines and cell therapy products.

  • Research
    Endotoxin quantification in laboratory and R&D studies.

  • Contract Laboratories
    Reliable methods for routine testing services.
