Industrial Applications of CARBOXYPEPTIDASE B
| Industry | Application | Process |
|---|---|---|
| Biopharmaceuticals | Used in structural and functional studies of proteins and peptides; employed as an enzymatic tool for cleaving peptide chains in molecular biology assays | Enzymatic digestion, proteolytic analysis, peptide synthesis and purification |
| Biotechnology | Used in recombinant protein expression systems for specific cleavage of basic amino acid residues (e.g., arginine or lysine) within peptide sequences | Protein modification, signal peptide removal, and protein maturation processing |
| Food Science | Applied in food composition analysis for detection and quantification of specific peptide species | Peptide degradation and analysis in food matrices |
| Research | Used as a model enzyme to study the conversion of proinsulin to insulin, supporting metabolic research | In vitro enzymatic conversion simulation |
| Medical Diagnostics | Involved in detection of certain disease biomarkers, supporting mechanistic studies of disease | Enzyme-linked reactions in immunoassays and biomarker detection |
Manufacturing Quality Control of CARBOXYPEPTIDASE B
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Enzyme Activity | Spectrophotometric Assay | Measures hydrolysis rate of specific substrate (e.g., hippuryl-L-arginine) at 254 nm by monitoring product formation over time. |
| Protein Concentration | UV-Vis Spectrophotometry (A280) | Quantifies protein based on absorbance at 280 nm using extinction coefficient and Beer-Lambert law. |
| Purity (SDS-PAGE) | Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis | Separates proteins by molecular weight; purity assessed via band intensity and absence of contaminating bands. |
| Residual Host Cell Proteins | ELISA | Uses antibodies to detect and quantify non-target proteins derived from expression host (e.g., E. coli). |
| 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 | Binds fluorescent dye (e.g., PicoGreen) to double-stranded DNA; quantification via fluorescence intensity calibration. |
| Heavy Metals | ICP-OES | Atomizes sample and measures elemental emission spectra to quantify metals (e.g., Pb, Cd, Hg, As) at trace levels. |
| Moisture Content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| pH | Potentiometric pH Measurement | Measures hydrogen ion activity using calibrated glass electrode and reference electrode in aqueous solution. |
| Microbial Contamination | Membrane Filtration and Colony Counting | Filters sample through sterile membrane, incubates on appropriate agar, and enumerates viable bacterial/fungal colonies. |
| Bioburden (Aerobic Plate Count) | Standard Plate Count Agar (SPCA) Method | Dilutes sample, plates on SPCA, incubates at 30-35 C for 48-72 h, and counts colony-forming units. |
| Sterility | Direct Inoculation into Culture Media | Inoculates sample into fluid thioglycollate and soybean-casein digest media, incubates for 14 days, and observes for microbial growth. |
