Nanoproteomics

Mass Spectrometry Service Specification

Nanoproteomics services are performed using nano-flow liquid chromatography and cutting-edge Orbitrap Fusion Lumos mass spectrometer.

 

Sample Preparation and Services

  • The QC of enzymatic hydrolysis is strictly controlled by LC-MS
  • DDA-Spectral Library generated using HPLC technology and sample fractionation
  • 2h/fraction; 2h for DDA analysis

 

Quality Standard

  • Summary includes all methods and data analysis
  • Reports provided in Excel or PDF format, RAW files available upon request

 

Turn Around Time

Typical 5-6 weeks from sample QC acceptance to data report delivery

 

Sample Requirements  

 SAMPLE TYPE   AMOUNT NOTE
 Library construction samples Mammalian cells from similar or adjacent parts  5×105 More than 50 µg protein can be extracted

Tissue from similar or adjacent parts

10 mg

Nanoscale samples

Mammalian cells  > 100 Collected cells or tissues (not LCM) with 200 µL low adsorption PCR tube and stored in 2-5 µL PBS solution
 Egg cell or early embryo cell  > 1, and 3-5 is better
 Tissue  1 mg
 LCM (Laser capture microdissection) Thickness of 10 µm, > 10 mm2

* By default, it include two parts; but nanoscale samples analysis can also be carried out if there are no suitable library construction samples
