Pierce™ Peptide Desalting Spin Columns Thermo Scientific™
Thermo Scientific Pierce Peptide Desalting Spin Columns are ready-to-use centrifuge spin columns that enable efficient desalting of peptide samples following enzymatic digestion. The polymer-based hydrophobic resin contained in each column provides excellent binding and recovery characteristics for...
Pierce™ C18 Spin Columns Thermo Scientific™
Matrix-assisted laser desorption ionization (MALDI) and electrospray ionization (ESI) mass spectrometry (MS) provide high sensitivity and mass accuracy; however, interfering molecules from the sample can result in reduced sensitivity and poor-quality spectra.
High Select™ Top14 Abundant Protein Depletion Resin Thermo Scientific™
Analysis of human fluids is often complicated by the presence of high concentrations of serum proteins, including albumin and IgG that can make up more than 70% of total serum protein. Removal of albumin, immunoglobulins, and other abundant proteins is essential for the study of low-abundance...
Pierce™ Intact Protein Standard Mix Thermo Scientific™
The Thermo Scientific Pierce Intact Protein Standard Mix is a high quality mixture of recombinant proteins for use as a quality control standard for LC and LC/MS, LC/MS method development, and intact protein mass measurements.
Invitrosol™ LC/MS Protein Solubilizer Kit Invitrogen™
The Invitrosol™ LC/MS (Liquid Chromatorgraphy/Mass spectrometry) Protein Solubilizer Kit contains a novel, proprietary surfactant blend for simplified preparation of hydrophobic and hydrophilic proteins or peptides for ESI (Electrospray Ionization) mass spectrometry (MS) experiments.
Pierce™ Quantitative Fluorometric Peptide Assay Thermo Scientific™
Pierce colorimetric or fluorescent quantitative peptide assays are easy mix-and-read microplate assays with stable signals for accurate and robust measurement of peptide digest samples. A high-quality peptide digest reference standard is provided as a stand-alone, or in the kits for use in the...
Pierce™ Trypsin/Lys-C Protease Mix, MS Grade Thermo Scientific™
Protein characterization, identification, and quantification by MS begins with efficient, reproducible protein digestion. Sequence specific proteases are utilized to cleave proteins into smaller fragments or peptides. Trypsin is the protease of choice for protein digestion.
