FAQ

Q1: What types of samples are suitable?

A1: Suitable samples include those with clear origin, good solubility, and basic purity, such as cell or tissue extracts, purified proteins, serum or plasma, recombinant proteins, and other samples that can undergo enzymatic digestion or be directly injected. For complex matrices or low-abundance samples, it is recommended to perform sample pre-treatment for better analysis results. If you have special sample types, it is advisable to consult us in advance for more accurate preparation suggestions.

Q2: What is the service general workflow?

A2:

Q3: What data formats are provided?

A3: MtoZ Biolabs provides various standardized output formats, including:

• Raw mass spectrometry data files (e.g., .raw format, platform-specific)

• Protein analysis results (Excel/CSV format)

• Analysis report in PDF format (including experimental methods, parameter settings, identification details, and statistical results)

• Visual charts (e.g., mass spectrometry graphs, peptide matching charts, in PNG/TIFF formats)

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

Q4: How should I prepare my samples?

A4: To ensure optimal analysis results, we recommend preparing your samples as follows:

(1) Sample purity: Avoid components like high salt, detergents, or other substances that may interfere with enzyme digestion or affect electrospray ionization.

(2) Sample storage: Short-term storage at 4℃ is acceptable; long-term storage should be at -80℃, avoiding repeated freeze-thaw cycles.

(3) Sample transport: Use cold transport (e.g., dry ice or ice packs) and ensure the packaging is sealed to prevent leakage or contamination.

(4) Additional information: Please provide sample type, concentration, buffer system, pre-treatment steps, and other relevant details, so we can tailor the most suitable analysis strategy for your needs.
