Great product, we can not work without it!
Application Area: Quality control for liquid chromatography/mass spectrometry.
"I'm very pleased with the service that the Sales representative Paul Banks provides. When I ask for the quote he is very efficient and he always offers a good discount. The product is a high quality, very consistent between the batches, fits for purpose. I am very happy with the product."
The mass spectrometry-compatible yeast and human protein extracts are designed specifically for mass spectrometry applications.
The extracts are predigested and cleaned up by solid-phase extraction for immediate use in liquid chromatography/mass spectrometry (LC/MS) analysis. Both the yeast and human extracts also are available in an intact undigested form to provide a test material for optimizing mass spec protein sample preparation. The yeast extracts are beneficial for users who prefer working with a relatively compact and well studied proteome, whereas the human extract provides opportunity for working with a complex proteome having a large dynamic range. Consistent extract protein composition is ensured by tight control over cell culture conditions and manufacturing process.
Lot-to-lot consistency of extracts is monitored by various protein and peptide qualitative and quantitation methods, including LC/MS and amino acid analysis (Table 1). Our manufacturing process assures compatibility with reverse phase liquid chromatography and mass spectrometry by monitoring nonspecific protein fragmentation, nonbiological post-translational modifications and, for digested extracts, minimal undigested peptides.
