Why use protein crosslinkers?

Protein crosslinking has become an important tool for the preparation of bioconjugates used in immunoassays, isotope labeled crosslinkers are used for probing protein-protein interactions by mass spectrometry, as well as other creative crosslinking methodologies that include:

  • Determining protein structure or spatial orientation of a protein
  • Studying protein-protein interactions
  • Forming carrier protein-hapten conjugates
  • Producing antibody-protein crosslinked conjugates
  • Covalently crosslinking proteins to a solid surface
  • Creating antibody-enzyme or fluorophore-peptides conjugates
  • Analyzing enzyme activity and protein degradation

Mass Spectrometry standards

Why calibrate your mass spectrometer with irrelevant standards when you can use ProteoChem’s peptide mass spec standards that are similar to your samples?

Peptide mass spectrometry standards from ProteoChem are purified peptide standards used for the calibration of mass spectrometry instruments. ProteoChem's mass standards are conveniently packaged for individual use. You are able to dissolve the calibration peptide in buffer or matrix solution right in the tube then analyze by mass spec, either MALDI-TOF MS or ESI-MS. ProteoChem's mass spec standards are the best available.

  • Leu-Enkephalin
  • Gonadoliberin
  • Angiotensin I
  • Neurotensin

UltraPure MALDI matrices

ProteoChem produces ultrapure matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS) matrix products. ProteoChem's UltraPure MALDI-MS matrices are purified by a propriety method designed to yield MALDI mass spectra with increased sensitivity, better resolution, and high signal to noise ratios by removing contaminating matter that can interfere with mass spectrometric analysis. ProteoChem's MALDI matrices are specialized and intended for analysis of proteins and peptides. ProteoChem's MALDI matrices are of the highest purity found in the market. These products are generally in the high 98-100% range.
