Manufacturing Quality Control of Epsilon-polylysine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 200-220 nm based on peak area comparison against reference standard. |
| Molecular Weight Distribution | SEC-MALS | Size-exclusion chromatography coupled with multi-angle light scattering to determine weight-average molecular weight and polydispersity. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to quantify water via stoichiometric reaction. |
| Residual Solvents | GC-FID | Gas chromatography with flame ionization detection to identify and quantify organic solvents (e.g., ethanol, acetone) based on retention time and peak area. |
| Heavy Metals | ICP-MS | Inductively coupled plasma mass spectrometry for simultaneous quantification of trace metals (e.g., Pb, Cd, As, Hg) after acid digestion. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Measurement using calibrated glass electrode in a 1% w/v aqueous solution at 25 C. |
| Loss on Drying | Gravimetric Thermogravimetry | Weight loss measured after drying at 105 C for 2 hours under atmospheric pressure. |
| Optical Rotation | [alpha]D Measurement | Specific optical rotation determined using sodium D-line (589 nm) in aqueous solution at specified concentration and temperature. |
| Endotoxin Level | LAL Assay | Limulus amebocyte lysate kinetic turbidimetric assay to detect and quantify bacterial endotoxins. |
| Microbial Contamination | Plate Count Method | Aerobic mesophilic count by pour plate or spread plate method on soybean-casein digest agar after incubation at 30-35 C for 3-5 days. |
| Residual Host Cell Proteins | ELISA | Enzyme-linked immunosorbent assay using antibodies specific to host cell proteins to quantify residual impurities. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities (e.g., shorter-chain polylysine oligomers, deamidated forms) using gradient HPLC-UV. |
