Manufacturing Quality Control of CECROPIN B
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase chromatography with UV detection at 214 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC with UV detection and relative response factors. |
| Water Content | Karl Fischer Titration | Measures water by volumetric or coulometric titration with iodine-based reagent where water reacts stoichiometrically. |
| Residual Solvents | GC-FID | Identifies and quantifies organic solvents using gas chromatography with flame ionization detection and external calibration. |
| Heavy Metals | ICP-MS | Determines trace metal contaminants (e.g., Pb, Cd, Hg, As) by mass spectrometric detection after acid digestion and dilution. |
| pH | Potentiometric Measurement | Measures hydrogen ion activity in aqueous solution using calibrated pH electrode and reference electrode. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid or solution against defined specifications under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of dry powder using angular scattering pattern of laser light through dispersed particles. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to culture media, and colony enumeration after incubation. |
| Endotoxin Level | LAL Assay | Quantifies bacterial endotoxins using Limulus amebocyte lysate enzymatic reaction that produces measurable gel clot or chromogenic signal. |
| Peptide Content (N-terminus) | Amino Acid Analysis (AAA) | Measures total amino acid composition after acid hydrolysis and derivatization, calculating peptide concentration from constituent residues. |
| Sterility | Direct Inoculation | Confirms absence of viable microorganisms by inoculating sample into soybean-casein digest and fluid thioglycollate media followed by incubation and observation. |
