Peptide fractionation
Improvement of protein identification by LC-MS/MS in complex biological samples such as plasma by peptide fractionation at basic pH.
BioSPE™ PepFrac is used for peptide fractionation by hydrophobicity at basic pH. This fractionation method being orthogonal to peptide separation by reversed-phase liquid chromatography, sample complexity is reduced for deep proteome sequencing and quantitative analysis.
The BioSPE™ PepFrac kit is composed of:
- Fractionation columns based on an innovative reversed-phase resin
- Adapters (for tips centrifugation) and/or collection tools (centrifuge tubes or collection plates). Each kit contains nine collection tools (one for the conditioning/loading/washing steps and one for each elution fraction)
- A detailed protocol for fast and efficient peptide fractionation (up to 8 fractions)
- Triethylamine (TEA) solution
To determine which format and capacity will best suit your needs, please refer to the tables in the “Formats & Capacities” tab.
- Increased number of identified proteins compared to unfractionated samples (up to 30% increase)
- Minimized fraction overlapping and good distribution of peptides in all fractions
- No desalting step required prior to LC-MS/MS analysis (contrary to fractionation by salt)
- No storage constraint (store dry at room temperature)
- Different formats available to adapt to sample volume and throughput (StageTips, Spin columns, 96 wellplates and SPE cartridges)
- Two capacities available for each format depending on your peptide amount
Details regarding the loading and elution volumes for our different BioSPE™PepFrac products to find the best product depending on your sample volume.
Information table regarding the capacities (maximal amount of peptides/proteins that can be retained) of our different BioSPE™PepFrac products :
- For Standard capacity, product references contain the letter S (e.g. Tips-PepFrac.S8.200.96).
- For High capacity, product references contain the letter H (e.g. Tips-PepFrac.H8.200.96)
