Founded in 1996, LifeSensors is a privately held biotechnology company located 35 miles west of Philadelphia. The main focus at LifeSensors is to develop enabling technologies to translate genome into proteome. The technology platform is based on an important family of proteins called ubiquitin or ubiquitin-like proteins (UBL), such as SUMO (Small Ubiquitin-like MOdifer). LifeSensors has filed patents to cover the use of UBL and SUMO as gene fusions to enhance expression and facilitate rapid purification of recombinant proteins. Currently, LifeSensors is expanding its protein expression and purification capabilities to develop human receptor based protein chips for drug discovery and diagnostics.
