Sonication – 7 Tips for Mastering the art

Sonication is mostly used during preparation of protein extracts to help break apart the cell. Although most lysis buffers have buckets of detergent that lyse cell membranes, sonication just gives an extra hand in breaking everything apart. Sonication also breaks up, or shears, DNA in a sample—preventing if from interfering with further sample preparation. Have […]

Isoelectric Focusing for separation of proteins and peptides

SDS-PAGE is the standard technique used for separation of proteins in the lab, but that doesn’t meant that other techniques don’t have their place–one such technique is isoelectric focusing (IEF). IEF, also known simply as electrofocusing, is a technique for separating charged molecules, usually proteins or peptides, on the basis of their isoelectric point (pI), […]
