Improve Trypsin Digestion & LC-MS Performance with Digestif Quality Control Reagent

Universal Quality Standards

Digestif comprises a soluble recombinant protein scaffold + 11 artificial peptides (iRT) with good ionization.
Amino acids flanking iRT cleavage site either favour or hinder protease cleavage.
Retention time & relative intensity pattern of released iRT can assess the quality of sample workup, the extent of digestion, LC-MS performance & inter/intra-lab variability



SIL Proteins for Quantitative Mass Spectrometry

Low Abundant Protein Quantification in Complex Matrices

The Promise Proteomics SIL proteins are of high purity and >99% isotopic incorporation. You get an internal standard with the same sequence as your target protein of interest, thus normalising for variation in sample digestion and purification processes.

Optimise conditions based on the affinity to different chelating metal ions:

Ni2+, Cu2+, Co2+ or Zn2+

The MagReSyn® NTA Screening Kit enables testing of all four alternatives

The MagReSyn® microparticles consist of nitrilotriacetic acid (NTA) residues with a strong metal-chelating property. MagReSyn® NTA is pre-chelated with nickel ions for affinity purification of histidine-tagged proteins. The product has been engineered for exceptional specificity, delivering highly pure target proteins. Since different types of His-tagged proteins may have varying affinities for a particular metal ion, we also offer a His-tagged protein purification screening kit (MagReSyn® NTA-KIT) containing MagReSyn® NTA chelated with 4 alternate divalent metal ions (Ni2+, Cu2+, Co2+, Zn2+) to identify the most suitable metal ion for optimal purification of your particular target protein. MagReSyn® NTA Copper, -Cobalt and -Zinc are currently available in 2
