Endotoxin Free DPBS Buffer for Critical Research Applications
OVERVIEW
EndoToxFree™ DPBS (1X), is an ultra-pure, USP Grade Dulbecco’s phosphate-buffered saline, formulated without calcium and magnesium. Manufactured under stringent conditions, ensuring an endotoxin level of <0.005 EU/mL, this buffer is specifically designed for sensitive cell culture and research applications where endotoxin contamination could compromise results.
UNDERSTANDING ENDOTOXIN CONTAMINATION
What Are Endotoxins?
Endotoxins are lipopolysaccharide (LPS) components found in the outer membrane of Gram-negative bacteria. Even in trace amounts, these toxic compounds can severely disrupt cell culture experiments and research outcomes.
Sources of Endotoxin Contamination
Raw Materials: salts and excipients can carry endotoxins if improperly processed
- Equipment and Surfaces: inadequate cleaning and sterilization increases risk
- Environmental Exposure: cross-contamination during handling or storage
Research Impacts of Endotoxin Contamination
Even trace amounts of endotoxins can severely affect your experimental results.
- Unwanted Immune Cell Activation – cytokine release in immune cell lines (e.g., THP-1, RAW 264.7)
- Compromised viability and differentiation of stem cells and primary cells
- Significant batch-to-batch variability in assay results
- False positive/negative results in inflammation-related assays
- Artificial immune activation leading to unreliable data
KEY BENEFITS OF EndoToxFree™ DPBS (1X), USP Grade
- Ultra-low endotoxin levels (<0.005 EU/mL) eliminate interference that can compromise your critical experiments
- USP Grade quality ensures high purity and consistent composition from batch to batch
- Calcium and magnesium-free formulation gives precise control over cell behavior
- Reliable, reproducible results across manufacturing lots
- Regulatory compliance support for smooth transitions from research to GMP manufacturing
Calcium and Magnesium Free for Enhanced Cell Control
- Supports cell detachment – Eliminating calcium and magnesium ions prevents ion-mediated cell adhesion during cell harvesting procedures.
- Prevents Unwanted Reactions – Calcium and magnesium can activate certain enzymes or signaling pathways, potentially affecting experimental outcomes.
- Avoids Precipitation or Contamination – In some biochemical or immunological experiments, these ions might cause unwanted precipitation or interactions
