Validation of RNAi Knockdown Using Multiple Reaction Monitoring and Protein-AQUA
The field of proteomics is continually looking for new ways to investigate protein dynamics within complex biological samples. Recently, many researchers have begun to use RNA interference (RNAi) as a method of manipulating protein levels within their samples, but the
Oligonucleotide Quality Control by Analytical HPLC
In many cases oligonucleotides require quantitative analysis to verify specifications have been met. MALDI-TOF and ESI-MS can provide qualitative-quantification for purity.
Rapid Determination of Protein Binding Affinity Using Solid Phase Microextraction
Accurate protein binding affinities were measured using bioSPME more rapidly than membrane dialysis (RED) techniques. Binding affinities correlated to the reference values.
Bioanalysis with SPME
Biocompatible SPME devices employ C18 bonded porous silica sorbent particles, in a binder which resists fouling by biological matrix components
Ascentis® Express Biphenyl UHPLC and HPLC Columns
The bonded, densely endcapped, dimethyl-biphenyl stationary phase of Ascentis® Express 90 Å Biphenyl, based on fused-core particles, provides a stable, reversed phase packing with enhanced π-π and mild steric interactions due to the two sequential phenyl groups bonded to the
Ascentis® Express C8 U/HPLC Columns
When a C18 doesn′t give the desired separation, or your sample contains compounds that are known to be difficult to retain or resolve on a C18, consider changing to an Ascentis® Express C8 column.
Supel™-Select Polymeric SPE
Supel-Select HLB SPE - a hydrophilic modified styrene based polymer developed for the solid phase extraction of a broad range of compounds from aqueous samples.
