Research Data
Analytical & COA Specifications
- Analytical Purity (RP-HPLC)
- ≥ 98.0% area normalization under UV detection at λ = 214 nm.
- Identity Confirmation (ESI-MS / MALDI-TOF)
- Confirmed against the reference mass specification recorded on the batch Certificate of Analysis.
- Residual Moisture (Karl Fischer Titration)
- ≤ 2.0% water content.
- Endotoxin Screening (LAL Assay)
- < 1.0 EU/mg (Limulus Amebocyte Lysate per USP <85>).
- Sterility Validation
- USP <71> compliant (no observed microbial proliferation).
- Physical Characterization
- Dense, white to off-white lyophilized solid cake/powder.
Handling & Stability
Storage. Store dry solid desiccated at −20°C to −80°C, protected from atmospheric moisture and direct light.
Solubility. Soluble in sterile laboratory-grade deionized water or sterile Phosphate-Buffered Saline (PBS, pH 7.4) for in vitro assay application.
- Handling & Aliquoting: Prepare concentrated stock solutions freshly or aliquot into single-use fractions at −20°C to minimize degradation from repeated freeze-thaw cycles.
Technical Laboratory FAQs
What documentation accompanies this reference standard?
Each batch is shipped with a Certificate of Analysis documenting purity, identity confirmation, residual moisture, and endotoxin results, and is linked to a QR-verifiable batch record.
How is this material qualified for laboratory use?
The lyophilized reference standard is characterized by reversed-phase HPLC, mass spectrometry, Karl Fischer titration, and LAL endotoxin screening, and is supplied for in vitro and analytical applications only.
What storage conditions maintain stability?
Store the dry solid desiccated at −20°C to −80°C; reconstituted stock solutions should be aliquoted and stored frozen to avoid repeated freeze-thaw cycles.
