Thermo Scientific™ 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. The MALDI method for MS peptide analysis is n

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 fo

The Thermo Scientific Pierce 6 Protein Digest Standard, Equimolar, LC-MS Grade, is a highly validated equimolar protein digest mixture for use as a quality control sample for mass spectrometry (MS) analysis of proteomic samples.Positive control sample -

Concentrations of albumin and IgG can make up more than 70% of total serum proteins and often mask lower quantity proteins during protein-profiling experiments. Optimize your serum sample prep by removing albumin or IgG quickly and conveniently. By using

Thermo Scientific™ Pierce APTS (3-aminopropyltriethoxysilane) is a silylation reagent for coating glass and silica surfaces to add primary amines, which can be used to crosslink and immobilize proteins and other molecules. APTS (3-aminopropyltriethoxysil
