MagReSyn TiO2 (10 ml)
Protein phosphorylation plays a pivotal role in most cellular processes, with 30% of the proteome transiently phosphorylated. It is therefore a widely studied post-translational modification. However, the low-abundant nature of phosphopeptides, the low stoichiometry of the modification, and the physico-chemical properties of phosphorylated peptides make proteome-wide characterization of phosphorylation a significant challenge to proteomics researchers. Consequently, technologies than can specifically enrich phosphopeptides, and are compatible with mass spectrometric analyses, are highly desirable. MagReSyn® TiO2 microparticles allow highly specific, reproducible enrichment of phosphopeptides from complex biological samples such as protein digests. Titanium dioxide enrichment shows selective affinity for phosphoserine (pSer), phosphothreonine (pThr) and phosphotyrosine (pTyr) residues. MagReSyn® TiO2 microparticles have been engineered to achieve the ultimate specificity, outperforming competitor products, with excellent phosphopeptide recovery.

MagReSyn Technology Description

New miniaturized, high throughput technologies for bioseparation, diagnostics, DNA sequencing, flow cytometry, drug discovery, proteomics and genomics are in many instances reliant on attachment of functional biological molecules to a microsphere support. The vast array of life sciences applications include: capture reagents for immunoassay (fluorescence, enzyme linked etc); surfaces for immunoprecipitation; diagnostic assays; fluorescence microscopy; flow/imaging cytometry; magnetic cell separation; molecular diagnostics; agglutination tests; nucleic acid separation and protein separation among others.

Conventional microparticle technologies use solid or porous/cracked microparticles with binding of biological molecules limited to the surface, a key factor constraining performance and the development of new applications for microparticle technologies and products. We have developed a novel (patented) microparticle technology platform, comprising a hyper-porous polymer matrix that allows penetration of biological and synthetic molecules throughout the volume of the microparticles. This offers exceptionally high surface area for binding of molecules and allows performance that is orders of magnitude greater than alternate technologies. The binding capacity serves as a major performance contributor to the number of applications and versatility for end-user applications by and further enables miniaturization, increased sensitivity and reducing the cost of R&D.
