Is mass spectrometry only used for protein analysis? - Biotec BiotechIntroduction to Testing Technology Services Details

Mass Spectrometry (MS) is an analytical technique that achieves d à nb á izh ì analysis and other molecular identification and quantification by measuring the mass to charge ratio (m/z) of sample molecules. Although mass spectrometry has been widely used in d à nb á izh ì omics, its applications go far beyond d à nb á izh ì analysis. Here are some other application areas of mass spectrometry technology:

1、 Metabolomics

Mass spectrometry is used to analyze small molecule metabolites such as sugars, lipids, amino acids, and nucleotides to study metabolic pathways and changes. Metabolomics is divided into untargeted metabolomics and targeted metabolomics. Non target metabolomics is an unbiased approach that seeks potential biomarkers through comprehensive detection of the metabolome and plays a role in disease typing and other fields. Targeted metabolomics focuses on specific metabolites, using GC/MS or LC/MS for qualitative and quantitative analysis, with the advantage of high sensitivity, but requires the development of standards and methods.

2、 Fat zh ì z ǔ xu é

Mass spectrometry is used to identify and quantify various lipid types such as phospholipids, esters, triglycerides, etc., expanding the field beyond d à nb á izh ì analysis.

3、 Nucleic acid analysis

Mass spectrometry analysis of DNA and RNA fragments can be used for DNA methylation research in epigenetics.

4、 Drug development and pharmacokinetics (DMPK)

Mass spectrometry is used for the analysis of drugs and their metabolites, studying the dynamic changes of drugs in vivo.

5、 Environmental Science

Mass spectrometry can efficiently detect and quantify environmental pollutants, including pesticides, industrial chemicals, and heavy metals.

6、 Food Safety and Quality Control

Mass spectrometry technology can detect additives, residues, and natural toxins in food, providing support for food quality control.

7、 Clinical diagnosis

Mass spectrometry is widely used in the discovery and diagnosis of biomarkers such as cancer and neurodegenerative diseases, promoting the development of d à nb á izh ì analysis in the medical field.

8、 Materials Science

Mass spectrometry is used to characterize the chemical structure and composition of polymers and nanomaterials.

9、 Food safety testing

Mass spectrometry can effectively detect allergens, pollutants, and adulterated ingredients in food.

Mass spectrometry, with its advantages of high sensitivity, high specificity, and high throughput, has become a core tool for d à nb á izh ì analysis and other research fields, and continues to expand its application scope.

Baitai Paike Biotechnology Characteristic Project

1、 Protein sequencing

Biotec Biotech uses Thermo's newly launched Obitrap Fusion Lumos mass spectrometer and Shimadzu's Edman degradation sequencing system to analyze the d à nb á izh ì sequence, providing mass spectrometry based protein sequencing analysis services, including amino acid composition analysis of d à nb á izh ì, Ndu ā nc è x ù, Cdu ā nc è x ù, and full sequence analysis, as well as d à nb á izh ì N-terminal sequence analysis services based on Edman degradation. For unknown theoretical sequences, we provide de novo sequencing services based on de novo sequencing to analyze protein sequences.

※ Service advantages:

1. Adopting the world's advanced mass spectrometer Obitrap Fusion Lumos;

2. It can achieve 100% coverage of the measured target protein sequence;

3. It can determine up to 70 amino acid sequences at the N-terminus of proteins;

4. Can measure various forms of samples: protein solution, PVDF protein bands;

5. Low sample usage: Protein samples only require 5-10ug to complete detection;

6. Sequencing is not affected by N-terminal modifications such as blocking, PEC, and glycosylation.

2、 D à nb á izh ì omics

Biotec Biotech uses Thermo Fisher's Orbitrap Fusion Lumos mass spectrometry platform combined with Nano LC to provide a variety of d à nb á izh ì omics analysis services, including quantitative d à nb á izh ì omics, targeted d à nb á izh ì omics, proteomics, post-translational modified proteomics, and more. In addition, Baitai Paike Biotechnology has launched a 4DD à nb á izh ì omics service based on timsTOF Pro, which helps with research in micro sample proteomics, large sample population medicine, and high-throughput modification genomics.

※ Service advantages:

1 . High throughput quantitative protein analysis: Large scale experimental analysis with multiple control groups, discovering new biomarkers;

2. Multiple in vitro and in vivo labeling methods are suitable for analyzing various samples such as tissues, cells, and blood;

3. High sensitivity of mass spectrometry analysis and high repeatability of experimental results;

4. Can detect low abundance proteins with a wide linear range;

5. Bioinformatics analysis is more systematic and accurate.

3、 Single cell mass spectrometry flow cytometry analysis

Baitai Paike Biotechnology uses the Fluidigm mass spectrometry flow cytometry system for single-cell mass spectrometry analysis. Metal element markers (usually metal element labeled specific antibodies) are used to label molecules on the surface and inside of cells. Then, individual cells are separated using flow cytometry principles, and the atomic mass spectrum of individual cells is analyzed using inductively coupled plasma mass spectrometry (ICP-MS). The atomic mass spectrum data is then converted into signal molecule expression levels on the cell surface and inside.

※ Service advantages:

1. Advanced technology, filling technological gaps

The use of metal labeled antibody technology avoids the problem of few and easily interacting channels in traditional flow cytometry fluorescence. At the single-cell level, multiple indicators can be characterized simultaneously, and Baitai Paike Biotechnology can detect 51 target proteins simultaneously.

2. Large analysis quantity and low cost

Single cell RNAseq is limited by factors such as cost, and the total number of analyzed cells for all samples is generally around 2x10 ^ 4. However, flow cytometry technology can analyze at least 10 ^ 5 cells in one sample, achieving an order of magnitude increase, and the cost is not higher than that of single-cell RNAseq.

3. Great application prospects

① The results of flow cytometry can provide changes in cell subpopulations, which have great research prospects in clinical diagnosis, disease mechanism research, and other fields;

② Combining metal tag technology with other technologies will lead to new application directions. In addition to conventional proteins, mass spectrometry flow cytometry technology can also be used for post-translational modification of proteins;

③ Can detect cell survival rate, cell size, mRNA transcript expression level, DNA synthesis rate, and protease activity.
