Integrated Proteomics

We identify various proteins within different samples using mass spectrometry-based methods and analyze quantitative changes to provide protein information associated with specific diseases or conditions.
PASS offers optimized services tailored to the needs of our customers using the ProteoID platform, including COFFER, BTS MS, BTS Reads, and BTS Systems.

Application

biomarker discovery, drug target discovery, PTM analysis, pharmaceutical CMC quality control
(exosome, PROTAC), characterization and process analysis of protein therapeutics (ADC, HCP)

Post-Translational Modification (PTM) Analysis

Provide analysis of PTMs (Post-Translational Modifications) in proteins that are difficult to interpretaste through RNA information.
Quantitative analysis of modified proteins and amino acids for the major in vivo PTMs (Phosphorylation, Acetylation, Methylation, Ubiquitination, Glycosylation).

Pharmaceutical CMC Quality Control

Quality control (QC) of novel drug modality such as exosomes and TPD (Targeted Protein Degradation; PROTAC)

Analysis of extracellular vesicle (exosome) therapeutics

Provide information for quality management to ensure equivalence and compliance to the ‘Development of Production Process and Quality Control Guidelines for Exosome-Based Therapeutics’ provided by the Ministry of Food and Drug Safety.

Analysis package: Comparative profiling of proteins, lipids, and RNA

TPD (Targeted Protein Degradation) Analysis

Provide the quantitative results of target protein degradation and regulation of downstream pathway proteins in response to drug treatment.
Bioinformatics analysis to elucidate the impact of off-target proteins. This approach allows us to under stand the effects exerted on off-target proteins in a comprehensive manner.

Analysis package: Proteomics and bioinformatics analysis

Targeted Proteomics

PASS provides accurate quantitative results based on targeted mass spectrometry approach such as MRM (Multiple Reaction Monitoring) and PRM (Product Reaction Monitoring) analysis.
This method utilizes internal standards (IS) in the form of isotopically labeled surrogate peptides for each target.
We have developed and provide a reproducible results that meets the validation guidelines outlined by the Ministry of Food and Drug Safety. This method ensures high reproducibility with a coefficient of variation (CV) of less than 15%.

Application

quality control of protein therapeutics (HCP), absolute quantification of proteins within samples, biomarker validation

Biopharmaceutical Quality Control (HCP)

We are capable of verifying the purity during the separation and purification of monoclonal antibody drugs and cell-based therapeutics.

Analysis package: Mass spectrometry-based analysis method
(Semi, Absolute quantification) as an alternative to ELISA analysis

Single Cell Proteomics

Single-cell technologies can serve as a starting point for the development of
effective personalized therapies and cures for diseases. In particular,
mass spectrometry-based single-cell proteomics provides unbiased results.
Bertis has introduced Bruker’s timsTOF SCP system, which provides meaningful
results even in true single-cell level.

Application

drug target discovery, spatial biology

Lipidomics

Lipids, consisting of over 4,000 diverse compounds, are present in various tissues and cellular compartments of the human body. They are being applied not only in cancer research but also in metabolic disease studies. The PASS service provides identification and quantification of lipids in samples using representative standard substances. Additionally, we provide profiling results of exosomal lipid composition according to the guidelines of the Ministry of Food and Drug Safety.

Application

quality analysis of new drugs (exosomes), Biomarker discovery

What is the process for PASS service?
What mass spectrometry instrument is utilized for PASS service?

PASS center provides services based on state-of-the-art mass analysis equipment.
What is the minimum sample requirement for sample preparation?

A minimum of 100 ug (at a concentration of 1ug/ul or higher) is required, and it is necessary to have a prior consultation regarding the quantity and condition of the sample.
How should the sample be delivered?

For cells, cell media, tissue, serum/plasma samples, please send them in a Styrofoam box with dry ice included.
For gel samples, please pack them and include an ice pack before sending.
How is QC conducted for the amount of protein?

After lysing the sample, it is measured using the BCA assay. It is also measured in the peptide state after digestion.

Is sample preparation performed by the client?

Typically, if customers send samples like those listed in the table below, skilled scientists at Bertis' PASS center will perform sample preparation in a form suitable for mass analysis.

	Required amount	Storage Condition	Notes
Cell	1x10^6	-20℃, -70℃	Prepared in a cell pellet state
Cell media	At least 20 ml	-20℃, -70℃	Concentration process required (FBS Free)
Tissue	At least 20 ml	-20℃, -70℃	Yield → approximately 3-5%
Serum/Plasma	100 ul or more	-20℃, -70℃	Abundant protein depletion required.
Gel	CBB, Silver staining	cold storage	Preparation to prevent the gel from drying or freezing

* Prior consultation is necessary regarding the quantity and condition of the sample.

How is LC-MS/MS analysis performed?

It is performed according to the following process based on profiling.

1. Lysis
: Denaturation of proteins using urea and guanidine
2. Reduction & Alkylation
: Use DTT (reduction), IAA (alkylation).
3. Digestion
: Use Trypsin, LysC.
4. Labeling and fractionation (for relative quantification)
: After TMT labeling, fractionation (12 or 24 fractions) to reduce complexity
5. LC-MS/MS analysis
: 200 min/ 1 run
6. Data analysis
What kind of results are provided?

The following information is provided according to the purpose of the experiment, and additional necessary information can be discussed through prior consultation.
- Report including sample information, experimental method, and basic results (ID graph, Venn diagram, etc.)
