In-Gel Tryptic Digestion Kit Thermo Scientific™

Accurate identification and analysis of proteins is a central component of proteomic strategies for studying cellular functions and processes. Using mass spectrometry, proteins and relevant post-translational modifications can be accurately identified, but the method is highly dependent on the...

EasyPep™ Magnetic MS Sample Preparation Kits and Proteomics Magnetic Clean-up Beads Thermo Scientific™

Proteomic sample preparation for MS analysis is complex, resulting in challenges with reproducibility and peptide quality. For MS sample preparation methods that utilize magnetic beads, a major challenge is the compatibility of the beads with the harsh conditions required for sample processing.

High-Select™ TiO2 Phosphopeptide Enrichment Kit Thermo Scientific™

Mass spectrometry (MS) is a key tool for identifying sites of protein phosphorylation and quantifying phosphorylation changes. However, MS analysis of protein phosphorylation is challenging due to the low stoichiometry, high hydrophilicity, poor ionization, and incomplete fragmentation of...

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™ MS-Compatible Magnetic IP Kit, Protein A/G Thermo Scientific™

Immunoprecipitation is often necessary for the detection and quantitation of low-abundance proteins or rare signaling events. Mass spectrometry analysis relies on two methods for the detection of low-abundance proteins: single reaction monitoring (SRM) and parallel reaction monitoring (PRM), which...

SA MALDI Matrix, Single-Use Thermo Scientific™

The Thermo Scientific SA MALDI Matrices are highly purified, recrystallized reagents packaged in convenient single-use tubes sufficient for analyzing up to 96 samples by matrix assisted laser desorption ionization.
