Dipotassium EDTA (K₂ EDTA) is a high-purity chelating agent supplied as a dry powder and optimized for interference testing in biochemical and clinical assay workflows. With a molecular weight of 404.45 g/mol, this compound is widely used to sequester divalent metal ions such as calcium and magnesium, thereby preventing unwanted enzymatic activity and stabilizing analytes during sample preparation.

Packaged in 250 mg aliquots and stored at room temperature, this biotechnology-grade reagent is ideal for validating assay performance under chelation stress, assessing anticoagulant interference, and benchmarking tube-to-tube variability. K₂ EDTA is commonly used in hematology, immunoassays, and protein quantification workflows. All solutions are prepared using Type I ultrapure water (resistivity >18 MΩ·cm) and filtered through 0.22 µm membranes to ensure reproducibility and analytical integrity.

Key benefits:

  • High-purity K₂ EDTA powder for interference and chelation studies
  • Validated for use in hematology, immunoassays, and protein workflows
  • Packaged in 250 mg aliquots; stable at room temperature
  • Supports anticoagulant interference testing and assay robustness
  • Biotechnology grade; filtered and reconstitutable in ultrapure water

Indication for Use:
This product is for Research Use Only (RUO). This product is not for administration to humans or animals. This product is not for human or veterinary diagnostic or therapeutic use.
