Extraction Assay Service
At Creative Biolabs, we provide a definitive solution to one of the most persistent hurdles in bioprocessing: lipopolysaccharide (LPS) contamination. Endotoxins are highly resilient, heat-stable molecules that can compromise the validity of in vitro assays and cause life-threatening inflammatory responses in vivo. Our service is engineered to deliver pharmaceutical-grade purity for sensitive biologics, ensuring that your research is based on the true biological activity of the target molecule rather than the artifacts of contamination.
Introduction to Endotoxin Extraction Mechanisms
The extraction assay for endotoxin removal is a specialized biochemical process that exploits the hydrophobic properties of lipid A to separate it from hydrophilic target molecules. Peer-reviewed scientific reports underscore that liquid-liquid partitioning, particularly using Triton X-114, is highly effective for reducing endotoxins in protein and phage preparations. Creative Biolabs utilizes these scientifically validated principles alongside patented affinity ligands to achieve near-absolute purity, ensuring that therapeutic candidates are free from pyrogenic interference and ready for advanced preclinical evaluation.
Key Problem-Solving Capabilities & Deliverables
Creative Biolabs offers high-performance phase-partitioning solutions designed to maximize endotoxin depletion while ensuring the structural integrity and high recovery of your therapeutic proteins and bacteriophages.
Ultra-High Removal Efficiency
We utilize optimized Triton X-114 and 1-octanol extraction protocols to achieve a 1000-fold reduction in endotoxin levels, ensuring your biological samples meet the most stringent pharmaceutical purity standards for clinical applications.
Ion-Independent Purification
Our patented Miro2p12 technology enables high-efficiency endotoxin removal in standard PBS and citrate buffers without requiring bivalent cations, preventing the common issue of sensitive protein aggregation during the purification process.
Advanced Detergent Polishing
We implement rigorous secondary purification steps using bio-beads SM-4 and gel filtration to reduce residual surfactants to below 0.01%, guaranteeing that your final product is non-cytotoxic and safe.
Comprehensive Analytical Validation
Every project includes rigorous quantification using kinetic chromogenic LAL or MAT assays, accompanied by a detailed technical data package documenting log-reduction, protein recovery rates, and residual solvent analysis.

Why Choose Creative Biolabs?
Creative Biolabs stands at the forefront of endotoxin mitigation, combining proprietary technologies with decades of chromatographic expertise. Our unique advantage lies in our ability to handle complex biological matrices that traditional chromatography methods often fail to purify effectively. According to "published data," our extraction protocols achieve a consistent 3-log (1000-fold) reduction in endotoxin levels with minimal protein loss (often <5%), which is essential for preserving high-value recombinant leads. Unlike generic services, we utilize ion-independent technologies that facilitate purification in standard PBS and citrate buffers. This prevents the aggregation of sensitive proteins that occurs when bivalent ions are required. Creative Biolabs ensures that your lead optimization is never compromised by the structural alterations often associated with harsh purification methods.

FAQs
Will the detergents used in the extraction assay denature my protein?
Creative Biolabs primarily uses non-ionic surfactants like Triton X-114, which are specifically chosen for their gentle, non-denaturing properties. Our protocols are optimized to maintain the native conformation and biological activity of your target throughout the phase separation process.
Can this service be applied to bacteriophage preparations?
Yes. We offer specialized 1-octanol and Miro2p12 extraction protocols specifically optimized for phage lysates, which effectively remove LPS from phage tail proteins while maintaining high viral titers.
Is your service compatible with buffers like PBS or Citrate?
Absolutely. Our patented ion-independent technology allows for high-efficiency extraction in standard PBS and Citrate buffers, eliminating the need for bivalent cations that might interfere with your sample's stability.
Customer Review
-
Exceptional Protein Recovery
Using Creative Biolabs' extraction assay in our research has facilitated the purification of our low-abundance serum proteins. We were concerned about yield, but the 98% recovery rate was far superior to the traditional ion-exchange methods we had previously attempted. – Dr. Micheal S*** -
Validated Phage Purity
The 1-Octanol extraction service improved our bacteriophage therapy project. It removed both endotoxins and enterotoxins, which was critical for our regulatory submission. The removal of residual solvent was flawless and didn't interfere with our LAL readouts. – Prof. Elena R***
