Manufacturing Quality Control of β-Lactoglobulin
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Protein Content | UV-Vis Spectrophotometry at 280 nm | Measures absorbance of aromatic amino acids (Trp, Tyr) in protein; quantified using molar extinction coefficient. |
| Purity by SDS-PAGE | SDS-Polyacrylamide Gel Electrophoresis | Separates proteins by molecular weight under denaturing conditions; purity assessed via band intensity and absence of contaminating bands. |
| Molecular Weight | Size Exclusion Chromatography (SEC) | Separates molecules based on hydrodynamic volume; calibrated with protein standards to determine monomeric and oligomeric forms. |
| Residual Moisture | Karl Fischer Titration | Quantifies water content via coulometric or volumetric titration using iodine-based redox reaction. |
| pH | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode and reference electrode. |
| Endotoxin Level | Limulus Amebocyte Lysate (LAL) Assay | Detects endotoxins via enzymatic cascade triggered by bacterial lipopolysaccharide, measured turbidimetrically or chromogenically. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomizes and excites sample in plasma; detects metal-specific emission wavelengths for quantitative multi-element analysis. |
| Residual Host Cell Proteins | ELISA | Uses antibodies specific to common host cell proteins to detect and quantify impurities via enzyme-linked colorimetric signal. |
| Bioburden | Membrane Filtration and Plate Count | Filters sample through sterile membrane, then incubates on nutrient agar; colony-forming units (CFU) enumerated after incubation. |
| Aggregate Content | Dynamic Light Scattering (DLS) | Measures fluctuations in scattered laser light intensity to determine particle size distribution and detect soluble aggregates. |
| Isoelectric Point (pI) | Isoelectric Focusing (IEF) | Separates proteins in pH gradient gel based on charge; pI identified by comparison to pI markers. |
| Loss on Drying (LOD) | Gravimetric Analysis | Measures mass loss after controlled heating under specified time/temperature conditions to determine volatile content. |
