Comprehensive Peptide Purity Analysis Service

Peptide purity is an essential metric for assessing the concentration of target peptides in synthetic peptide products, critically influencing the outcomes and quality of biomedical research and drug development. The purity of peptides depends on the quality of raw materials, synthesis methods, and post-synthesis treatments. Typical impurities include peptides with missing or truncated sequences, sequences with residual protective groups, and synthesis byproducts.

 

At MtoZ Biolabs, we utilize the Orbitrap Fusion Lumos mass spectrometry platform by Thermo Fisher, paired with nano-liquid chromatography, to deliver peptide purity analysis services. This platform enables precise detection and quantitative assessment of impurities in peptide samples. We further enhance our analysis by incorporating ultraviolet light detection (UV detection), providing a spectrum of services from basic purity tests to comprehensive impurity profiling.

 

Analysis Workflow

1. Sample Preparation

Treat peptide samples by dissolving and filtering to prepare them for analysis.

 

2. HPLC Analysis

Employ advanced RP-HPLC techniques to determine peptide purity through chromatographic quantification, and assess potential byproducts qualitatively and quantitatively.

 

3. MS Analysis

Use electrospray ionization (ESI MS) and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF MS) mass spectrometry for accurate determination of peptide molecular weights and structural confirmation.

 

4. Data Analysis and Report Generation

Utilize sophisticated software for analyzing data from HPLC and MS, producing detailed analytical reports.
