Many recombinant proteins (rec. proteins) are now commercially available. And many of them, mainly secreted soluble proteins, are biologically active, so there shouldn't be any need to look for alternatives

Isolation of highly purified untagged proteins is crucial in today's R&D programs. Up to now, recombinant protein production approaches were often based on the use of "tags" to make protein purification

Pharmaceutical, biotech and medical device industries apply restrictive quality systems in their bio-production processes. Among the numerous parameters controlled daily by scientists, I have selected

SUMO-tag gene fusion acts as both a chaperonin and as an initiator of protein folding in both prokaryotic and eukaryotic systems. Addition of this tag enables protein experts to increase the expression

In a previous post, we looked at the importance of sample preparation methods depending on the biomarker being studied (e.g. MMPs, cytokines). Today, let's focus on cell / tissue lysates.

Tip #1

Traditional methods to detect and purify poly-ubiquitinated proteins require either anti-ubiquitin antibodies or Ubiquitin Binding Associated domains (UBAs). Most of the current methods display rather

Antibody-based techniques are widely used in Life Science laboratories. Antibody purification is often required to raise purity yield of antibody production batches or to reach publication-grade

…or how to make your protein attractive

Biomagnetic separation is a powerful lab tool in protein biochemistry which can be used in a wide range of applications including analysis tools (for protein solubility

Polyethylene Glycols (aka. PEGs) are biologically inert, non-immunogenic, and hydrophilic molecules. These properties make them very attractive for research and drug discovery applications (ex. Antibody-Drug
