Manufacturing Quality Control of Pepsin
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Enzyme Activity | Spectrophotometric Assay (UV-Vis) | Measures hydrolysis rate of hemoglobin or N-acetyl-L-phenylalanine ethyl ester at 280 nm or 340 nm, proportional to enzymatic activity. |
| Protein Content | Lowry Assay | Quantifies protein via copper-chelation and Folin-Ciocalteu reagent reduction, yielding blue color measured at 750 nm. |
| Moisture Content | Karl Fischer Titration | Determines water content by stoichiometric reaction of iodine with water in methanol/pyridine solvent. |
| pH | Potentiometric Measurement | Measures hydrogen ion activity using calibrated glass electrode and reference electrode in aqueous solution. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Ionizes sample and detects metal isotopes based on mass-to-charge ratio with high sensitivity and multi-element capability. |
| Residual Solvents | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic solvents using flame ionization detection after thermal desorption. |
| Microbial Contamination | Membrane Filtration and Plate Count | Filters sample through membrane, incubates on appropriate agar, and counts viable colonies per USP <61>. |
| Endotoxin Level | Kinetic Turbidimetric LAL Assay | Measures endotoxin-induced clotting enzyme cascade in Limulus amebocyte lysate, detected as turbidity increase over time. |
| Specific Absorbance (A1cm 280nm) | UV-Vis Spectrophotometry | Determines purity by measuring absorbance at 280 nm of a 1 mg/mL solution in water, normalized to 1 cm pathlength. |
| Residual Host Cell Proteins | ELISA | Uses antibody-based capture and enzymatic detection to quantify trace host cell proteins from production system. |
| Particle Content | Light Obscuration | Counts and sizes suspended particles in liquid formulation by detecting light blockage as particles pass through laser beam. |
| Sterility | Direct Inoculation into Culture Media | Inoculates sample into soybean-casein digest and fluid thioglycollate media, then monitors for microbial growth per USP <71>. |
