A protein solubilisation buffer for 2D analysis must solubilise proteins effectively, without disturbing the native charge of the proteins. Urea based solubilisation buffers solubilise proteins effectively, however can modify the native charge of the proteins, due to carbamylation. Urea exists in equilibrium with ammonium cyanate that modifies α- and ε-amino groups, inducing changes in the isoelectric point of proteins leading to artifactual results.

Tissue PE LB™ has been developed for extraction of total biologically active, soluble proteins from animal tissues. Tissue PE LB™ is based on an organic buffer and utilises a mild non-ionic detergent, chelating agent, and a proprietary combination of various salts and agents to enhance extraction and stability of proteins. Depending on the required downstream application, additional agents such as reducing agents and protease inhibitors may be added into Tissue PE LB™. Tissue PE LB™ has been tested for use with a wide variety of fresh and frozen animal tissues.

The NE-PER Nuclear and Cytoplasmic Extraction Kit provides for efficient cell lysis and extraction of separate cytoplasmic and nuclear protein fractions in less than two hours. The nuclear protein extraction method involves simple, stepwise lysis of cells and centrifugal isolation of nuclear and cytoplasmic protein fractions. A benchtop microcentrifuge, tubes and pipettors are the only tools required. The NE-PER Reagents efficiently solubilise and separate cytoplasmic and nuclear proteins into fractions with minimal cross-contamination or interference from genomic DNA and mRNA. The isolated proteins can be used to perform immunoassays as well as protein interaction studies such as mobility shift assays (EMSA), co-immunoprecipitation (Co-IP) and pull-down assays.

EDTA (ethylenediaminetetraacetic acid) is a polyamino carboxylic acid. It is a colorless, water-soluble solid and is useful as a chelating agent due to its ability to "sequester" metal ions such as Ca2+ and Fe3+.  These cations are responsible for various undesirable effects in molecular biological and cell culture processes. After being bound by EDTA, these metal ions remain in the solution but exhibit diminished reactivity.  The use of EDTA therefore allows for greater control over many experiments.
