Maldi Tof Spectroscopy
Maldi tof spectroscopy is a rapidly advancing technology in bioanalysis. It offers unique advantages in areas such as proteomics, microbial identification, and drug metabolism research. MALDI-TOF MS allows for rapid and accurate mass analysis and component identification of samples. The technology, traced back to the 1980s, has expanded its applications with ongoing advances, becoming an essential tool in biomedical and chemical research. In proteomics, it is extensively used for protein identification, peptide mass fingerprinting, relative molecular weight determination, and protein interaction studies. Researchers can efficiently analyze complex protein mixtures to identify and quantify proteins. For microbial identification, Maldi tof spectroscopy is employed in clinical microbiology labs for identifying species like bacteria and fungi. Clinically, it enables rapid pathogen identification and early disease diagnosis through biomarker detection. Continuous technological innovation and method optimization promise to broaden its research applications further. MtoZ Biolabs offers a range of services to help clients leverage Maldi tof spectroscopy for scientific research and analysis.
Workflow of Maldi Tof Spectroscopy
1. Sample Preparation
(1) Sample Purification: Ensuring sample purity is crucial for successful MALDI-TOF MS analysis, as impurities may affect ionization efficiency and spectral stability.
(2) Matrix Selection: Selecting an appropriate matrix enhances sensitivity and resolution. Incorrect matrix mixing might reduce analyte ionization efficiency, affecting results. Common matrices include α-cyano-4-hydroxycinnamic acid and dihydroxybenzoic acid.
2. Data Collection and Analysis
(1) Laser Parameter Adjustment: Laser energy and pulse frequency should be optimized based on sample characteristics to improve ionization efficiency.
(2) Data Processing: Professional software processes and interprets spectra to identify target molecules’ mass-to-charge ratios.
