產品介紹

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   ☀ Gonadoliberlin   ☀ Angiotensin I   ☀ Neurotensin   ☀ Peptide Caliberin Standard

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.

Protein crosslinkers are chemical compounds used to covalently bind, or conjugate, biomolecules together. In proteomics, "protein crosslinking" refers to utilizing protein crosslinkers to conjugate peptides or proteins together or to immobilize proteins to a solid support. 

Deuterated crosslinkers manufactured by ProteoChem are high quality deuterium-labeled crosslinkers, or "heavy" crosslinker analogs, for isotopically labeling protein and peptides in mass spectrometry (MS) research applications. ProteoChem's unique offering of ultrapure, deuterated crosslinking reagents allows researchers to rapidly analyze protein structure and protein-protein interactions.

ProteoChem’s biotinylation reagents are offered as water soluble (Sulfo-NHS ester containing) or insoluble varieties. ProteoChem also offers biotins with diverse spacer arm lengths which can be used to reduce steric hindrances associated with streptavidin binding, thus allowing for more efficient binding of biotinylated proteins and peptides.

Protein modification reagents are useful for adding labels to or blocking functional groups on proteins, peptides, and other molecules. SATA, HPG, Traut's Reagent and Sulfo-NHS-Acetate are some of the best and most effective protein modification reagents available.
