For peptide fractionation

AttractSPE®Disks Tips C18 – Desalting

  • Microelution SPE Tips made with AttractSPE® Disks C18 sorbent: soft, thin and mechanically stable membrane, made of small sorbent particles tightly embedded, with reduced dead volume, small elution volume and high capacity
  • More than 97% proteins identified after desalting of HeLa digest on AttractSPE®Disks Tips C18 (200µL), with no loss of peptides
  • Good retention of peptides on the whole polarity range
  • Excellent repeatability (RSD < 3%)
  • Broad range of use: from single cell-like analysis (1ng) to high peptide amounts (> 10 µg)

BioSPE PepFrac – Fractionation

  • New reversed-phase resin based on Affinisep disks technology for peptide fractionation at high pH (orthogonal to RPLC peptide separation): reduction of sample complexity for deep proteome sequencing and quantitative analysis
  • Fractionation of 50µg peptides resulting from the tryptic digestion of proteins contained in HEK cells: 8 fractions with ACN gradient (2% to 50%) on BioSPETM PepFrac 200µL Tips
  • High number of proteins identified (increase of 20% compared to unfractionated samples)
  • Good distribution of peptides in all fractions and efficient fractionation with minimum fraction overlapping
  • Results similar to competitor fractionation kit but no storage constraints for BioSPETM PepFrac (store dry at room temperature) and evaporation time divided by two
  • Flexibility of format and capacity: BioSPETM PepFrac available as spin columns for high peptide amounts and as 96 wellplates for high throughput experiments

This tutorial video is for simple analysis of Glyphosate and its metabolites without derivatization in Complex Matrix!

AFFINIMIP®SPE Glyphosate is a very powerful kit for the cleanup of glyphosate, AMPA and glufosinate in water and food. This kit is supplied with a ready-to-use protocol for several tested matrices such as tea, honey, cereals… These applications are also gathered in an application notebook.

To make your life even easier, we have now prepared a tutorial video with tips and tricks.

Or course, our technical support remains available to help you to implement these methods if required…

Passive samplers based on SPE disks is an easy and reliable way to monitor hydrophilic contaminants including emerging compounds in natural waters for long periods.

SPE disks are easy to handle before and after the exposure on the field, strongly reducing risks of loss of information during these steps.
 More particularly, AttractSPE®Disks HLB is becoming the workhorse of this field thanks to the large range of molecules this disk can uptake.   In recent publications, major organizations in passive sampling have used AttractSPE®Disks HLB to monitor contaminants emerging concerns (CEC) in UK or in Central Europe. More than 150 pharmaceuticals, illicit drugs, drug metabolites, personal care products and pesticides were checked.
