GELFrEE 8100 Fractionation System

October 5th, 2018

GELFrEE Fractionation for Sample Preparation Successful sample preparation is a key step during any analytical procedure and begins with a defined experimental design. Important steps in sample preparation include proteolytic digestion of proteins into peptide fragments, and peptide fractionation. This is especially important prior to applications such as mass spectrometry (MS). For “bottom up” proteomics,…

Pre-Cast vs Hand-Cast Gels for SDS-PAGE

July 31st, 2018

Hand-cast gels can delay workflows Hand-cast gels are time-consuming to prepare and, when poured badly, result in irregular bands or streaking of proteins. This makes quantitation difficult and can delay workflows while experiments are repeated. Further disadvantages of hand-casting include the high potential for introducing user-bias and the susceptibility of hand-casting apparatus to leakage. There…
