MtoZ Biolabs employs a high-resolution mass spectrometry analysis platform to launch body fluid proteomics solutions enabling systematic characterization of protein composition and expression features across multiple body fluid sample types. This service is widely applied in body fluid proteome profiling and comparative sample analysis, providing reliable data support for body fluid-related proteomics research.

Overview

Body fluid proteomics is a research field that focuses on the systematic analysis of protein composition, types, and characteristics in body fluids such as blood, plasma, urine, cerebrospinal fluid, and saliva. Proteins present in body fluids originate from diverse sources, exhibit complex compositions, and display dynamic variation, allowing molecular states of biological systems to be reflected at an overall level. Body fluid proteomics has important applications in sample characterization, biomarker screening, molecular functional association studies, and multi-omics integrative analyses.

FAQ

Q1: What types of samples are suitable?

A1: Body fluid proteomics solutions are suitable for body fluid samples with clear origin, stable condition, and no obvious contamination, such as serum, plasma, cerebrospinal fluid, urine, and saliva. Samples should avoid evident hemolysis, lipemia, or microbial contamination and demonstrate good reproducibility to ensure the reliability and comparability of proteomics analysis results.

Q2: What is the service general workflow?

A2:

Q3: What data formats are provided?

A3: MtoZ Biolabs provides standardized data deliverables, which typically include:

• Protein identification and quantitative analysis result tables (Excel/CSV)

• Related statistical and summary files

• Mass spectrometry spectra and visualization results (PNG/TIFF)

• Raw acquisition data files

• Comprehensive analysis report (PDF, including an overview of the analytical workflow and result interpretation)

If special analytical requirements exist, data formats can be customized according to project specifications.

Q4: How should I prepare my samples?

A4: To obtain stable and reproducible results, the following recommendations should be considered:

(1) Sample Quality: Ensure that body fluid samples are clear, free of visible precipitation or contamination, and avoid high-salt or interfering components.

(2) Sample Storage: Short-term storage at 4℃ is acceptable; for long-term storage, -80℃ is recommended. Repeated freeze-thaw cycles should be minimized.

(3) Sample Transportation: Ship samples under low-temperature and sealed conditions to prevent protein degradation or compositional changes.

(4) Additional Information: Providing details on sample type, collection method, processing procedures, and relevant background information will help optimize the analytical strategy.
