Manufacturing Quality Control of Aprotinin
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Protein Content | UV-Vis Spectrophotometry at 280 nm | Measures absorbance of aromatic amino acids (Trp, Tyr) to quantify protein concentration based on Beer-Lambert law. |
| Purity by SDS-PAGE | SDS-Polyacrylamide Gel Electrophoresis | Separates proteins by molecular weight under denaturing conditions; purity assessed by band intensity and absence of extraneous bands. |
| Biological Activity | Enzyme Inhibition Assay using Trypsin | Quantifies inhibitory activity by measuring residual trypsin activity after incubation with抑肽酶; expressed as units/mg protein. |
| Residual Host Cell Proteins | ELISA | Uses antibodies specific to host cell proteins to detect and quantify trace contaminants from expression systems. |
| Endotoxin Level | Limulus Amebocyte Lysate (LAL) Assay | Measures endotoxin via coagulation cascade activation in horseshoe crab lysate, detected turbidimetrically or chromogenically. |
| Residual DNA | Fluorometric DNA Quantitation (e.g., PicoGreen) | Binds double-stranded DNA with fluorescent dye; fluorescence intensity correlates with DNA concentration. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine-based reagent to quantify water content by stoichiometric reaction. |
| pH | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode and pH meter in aqueous solution. |
| Osmolality | Freezing Point Depression Osmometry | Measures depression of freezing point in solution to calculate total solute concentration. |
| Sterility | Membrane Filtration followed by Incubation | Filters sample through sterile membrane, then incubates membrane on growth media to detect viable microorganisms. |
| Aggregate Content | Size Exclusion Chromatography (SEC-HPLC) | Separates species by hydrodynamic volume; quantifies monomeric vs. aggregated forms based on retention time. |
| Related Substances | Reversed-Phase HPLC | Separates impurities and degradation products based on hydrophobicity using C18 column and UV detection. |
