Sustainable Endotoxin Testing in China: Chromogenic Assay by Leading Suppliers and Factory for Reliable Results
Products Features
Animal-Free & Sustainable
Utilizes recombinant technology to eliminate dependency on horseshoe crab blood, supporting conservation efforts and promoting animal welfare without compromising reagent supply.
Native Cascade Mechanism
Comprising recombinant Factor C, Factor B, and proclotting enzyme, the reaction mechanism closely mirrors native LAL, ensuring high correlation with conventional methods.
Enhanced Specificity
Not activated by (1→3)-β-D-glucans, eliminating false-positive results and significantly improving test accuracy and reliability in complex pharmaceutical matrices.
Regulatory Compliance
Supported by emerging pharmacopeial standards, such as the proposed USP <86> chapter, facilitating smooth adoption in regulated laboratory environments.
Frequently Asked Questions
Q: What is Recombinant Cascade Reagent (RCR)?
RCR is a sustainable and highly specific recombinant alternative to traditional Limulus Amoebocyte Lysate (LAL) used for bacterial endotoxin testing in the pharmaceutical industry.
Q: How does RCR contribute to animal welfare and conservation?
By utilizing recombinant technology, RCR is produced through an entirely animal-free process. This eliminates the dependency on horseshoe crab blood, supporting global conservation efforts.
Q: Does RCR perform similarly to traditional LAL methods?
Yes. RCR contains recombinant Factor C, Factor B, and proclotting enzyme, creating a cascade reaction mechanism that closely mirrors native LAL and delivers highly comparable results.
Q: How does RCR prevent false-positive results?
Unlike native LAL, RCR is not activated by (1→3)-β-D-glucans, which are common sources of false-positives, thereby improving test accuracy in complex sample matrices.
Q: Is RCR recognized by regulatory pharmacopeial standards?
Yes, its adoption is supported by emerging standards such as the proposed USP <86> chapter, "Bacterial Endotoxins Test Using Recombinant Reagents," facilitating its use in regulated environments.
