Product Description

MOAC micro-SPE cartridge for enrichment of low concentration phosphopeptide samples
TiO2 • ZrO2 • Mixed TiO2/ZrO2
[AUTOMATABLE]

  • Simple, fast enrichment with minimal sample loss
  • MOAC NuTip enriches phosphorylated Ser, Tyr, and Thr, in a highly sensitive and reproducible way, with minimal non-specific binding
  • Media directly embedded on inner cartridge wall (no matrix) for reduced contamination, no back pressure
  • Different sizes to accomodate samples of varying volumes/concentrations (e.g., as small as 0.1 µL volume)

Phosphopeptide Enrichment NuTip provides MOAC, one of the most widely used strategies in phosphoproteomics, powered by Glygen’s patented NuTip micro-SPE technology. This enables separation of low-concentration phosphopeptide samples by maximizing media surface area in contact with the sample.

MOAC media is embedded directly in the inner surface of the tip: there are no polymers, glues or matrices. This proprietary design prevents contamination or permeability problems common in competitor tips.

How NuTip works

how-to-nutip.png


Media selection
Phosphopeptide Enrichment NuTips embedded with proprietary MOAC media. The literature suggests only 30% overlap in phosphopeptides isolated by TiO2 vs. ZrO2, emphasizing importance of an informed (and perhaps mixed-media) approach to enrichment.

Media Use for
TiO2 Selective for multiply phosphorylated peptides
ZrO2 Selective for monophosphorylated peptides
TiO2 / ZrO2 mixed media Broad spectrum


Specifications
Sold in packs of 96 tips.

NT1 1-10 1 µg 30 µg
NT2 10-200 2.5 µg 75 µg
NT3 10-200 15 µg 400 µg
