WebOct 11, 2016 · Selective enrichment of phosphopeptides is a key factor for successful detection of protein phosphorylations. Here, three types of mesoporous nanoparticles, ZnSn(OH) 6, P 0.5 –Ti-40 and P 0.5 –Ti-50, were evaluated for their efficiency in enriching phosphopeptides from β-casein and Arabidopsis thaliana leaf protein tryptic digests and … WebPhosphopeptides are subsequently eluted from the IMAC material using alkaline buffers such as ammonia water (pH 10–11). Alternatively, phosphopeptides can be eluted with EDTA , highly acidic solutions or solutions including phosphate or phosphoric acid [15, 21]. The eluted phosphopeptides should be desalted and concentrated by reversed phase ...
