Protein identification

Protein identification using 5800 MALDI-TOF/TOF (SCIEX)
We provide protein identification service to facilitate the gel-based proteomics approach. Customer will provide gel plugs containing protein and we will perform in-gel digestion, instrumentation analysis and database search using the Protein Pilot software. Upon completion, customer will be given the MASCOT (MatrixScience) search result by email.

Linear and reflector modes analyses using 5800 MALDI-TOF/TOF (SCIEX)
We provide linear and reflector modes analyses to obtain mass to charge ratio (m/z) or molecular weight (MW) of peptides, protein, phosphopeptides, small molecules, neutral carbohydrates, synthetic polymers and oligonucleotides. Upon completion, customer will be given the mass spectra result of the sample by email.

Zetasizer Nano S and ZS

TEST@INFORMM is an MS IEC/ISO17025:2017 accredited laboratory with capabilities for mechanical testing of measuring Monodisperse particle size analysis / 20nm-100nm using Zetasizer Instrument. TEST@INFORMM also offer other services as below:

Particle size and size distribution by DLS
Dynamic Light Scattering (DLS) is a method, which measures the frequency shift of laser light reflected by particles in suspension moving by Brownian motion. The distribution of particles speed is converted to a size distribution. The measurement range for size distribution is from 6 nm to 6 microns (sample dependent).

Zeta potential
Zeta potential is a measure of the magnitude of the electrostatic or charge repulsion/attraction between particles, and is one of the fundamental parameters known to affect stability. Its measurement brings detailed insight into the causes of dispersion, aggregation or flocculation, and can be applied to improve the formulation of dispersions, emulsions and suspensions. The most important factor that affects Zeta potential is pH. A Zeta potential value on its own without a quoted pH is a virtually meaningless number.

Autotitration
Equip with MPT-2 Autotitrator - Automates experiments to study the effect of a change in sample conditions such as pH, isoelectric point, conductivity, or the concentration of an additive. Up to three titrants can be used to increase and decrease pH.

Characterization of:

  • mean hydrodynamic diameter of particles in liquids
  • size distribution, polydispersion index
  • zeta potential
  • Isoelectric point (IEP)

Sample preparation requirements:

  • aqueous and organic suspensions (liquid sample)
  • minimum sample volume: 2.0mL
  • sample concentrations from 0.1ppm to 40%w/v (recommended 1mg/ml)
