MALDI TOF Bioanalytical Profiling Testing
The Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) is a powerful analytical technique widely used in the pharmaceutical sector for bioanalytical profiling. This method allows for rapid, accurate identification and quantification of peptides, proteins, and other biomolecules within complex biological matrices.
At our laboratory, we employ MALDI-TOF technology to provide comprehensive bioanalytical testing services that cater specifically to the needs of the pharmaceutical industry. Our expertise lies in providing high-quality data for drug development, quality control, and regulatory compliance.
The process begins with sample preparation, where we carefully extract biomolecules from biological samples such as plasma, serum, or cell cultures. This step is crucial as it directly influences the accuracy of subsequent analyses. The prepared samples are then introduced into the MALDI-TOF instrument for analysis.
During the analysis, laser pulses ionize and desorb molecules from the sample surface, which are subsequently accelerated through a vacuum tube towards an electron detector. The time-of-flight (ToF) is measured as the ions pass through this path, allowing us to determine their mass-to-charge ratio (m/z). This information is used to generate a spectrum that provides detailed insights into the molecular composition of the sample.
The precision and sensitivity of MALDI-TOF MS make it an ideal tool for various applications within pharmaceutical testing. It can be utilized in drug metabolism studies, protein mapping, peptide quantification, and post-translational modifications analysis among others.
Our team is committed to ensuring that all tests meet the highest standards set by international guidelines including ISO/IEC 17025:2017 for laboratory accreditation. We adhere strictly to these standards to guarantee reliable and reproducible results.
| Sample Type | Test Parameters | Instrumentation |
|---|---|---|
| Blood Plasma | PepMap, Peptide Quantification | MALDI-TOF MS |
| Cell Culture Supernatants | Protein Mapping | MALDI-TOF MS |
In summary, MALDI-TOF bioanalytical profiling testing offers a robust solution for detailed molecular characterization in pharmaceutical research and development. Its ability to provide rapid results with high accuracy makes it an indispensable tool in our laboratories.
