Tuesday, April 18, 2017

What is protein enrichment and why is there a need for it? Basically, protein enrichment is a technique where proteins of interest in a biological sample are concentrated to make them more suitable for identification and downstream analysis. ..

Importance of detergent micelle levels in membrane protein purification
Tuesday, April 11, 2017

Detergents  form micelles which can trap hydrophobic molecules into these micelles and allow the extraction of membrane proteins through solubilization.  The “Critical Micelle Concentration” or CMC of a detergent is the concentration of a detergent in which micelles start to form. ... ..
