Company Profile | Leadership | Publications | Press Releases
LifeSensors is a biotechnology company located in Great Valley Corporate Center, a biotech hub 35 miles west of Philadelphia, Pennsylvania, USA. Founded in 1996, the company develops and licenses innovative protein expression technologies enabling the efficient translation of the genome into the proteome.
LifeSensors is known for its innovations in an important family of proteins consisting of ubiquitin and ubiquitin-like proteins (UBL) such as SUMO (Small Ubiquitin-like MOdifier), marketing a series of ubiquitin pathway products, e.g., de-ubiquitylases, ubiquitin ligases.
LifeSensors holds several patents covering the use of SUMO and other UBLs as gene fusion tags to improve protein expression and purification and has filed for or licensed patents for novel assay technologies for de-ubiquitylases and ubiquitin ligases. LifeSensors helps client companies to improve the quality and quantity of their protein production and has expanded its production capabilities to assist customers and partners.
LifeSensors has leveraged its active protein production capabilities to develop Functional Protein Arrays and is proud to introduce first-in-class human de-ubiquitylase arrays (DUB Array). These protein arrays are used for drug discovery and diagnostics markets.
COMPANY HISTORY
October 2009LifeSensors launches ubiquitin ligase kits. Ubiquitin ligases, the largest family of proteins in humans, conjugate ubiquitin to the ligase target proteins. Ligases are highly attractive drug targets for a variety of diseases. LifeSensors’s ligase kits enable a user to assay any protein for ubiquitin conjugating activity or to assay the acceptor protein (ligase substrate). The modular nature of the kits allows one to select from various ubiquitin conjugating enzymes (E2s) as well as ubiquitin ligases (E3s). The modular assay is adaptable to small scale or large scale HTS.
September 2009
LifeSensors launches UBIQUITIN TRAPS to identify, purify, and characterize poly-ubiquitylated proteins. Nearly all cellular proteins are ubiquitylated at one time or other. Usually, ubiquitylated proteins are identified by immunoprecipition with antibodies against ubiquitin. Because ubiquitin is highly conserved, it does not elicit high affinity or immunoprecipitating antibodies. This problem has been solved by the development of poly-ubiquitin binding TRAPS that bind to poly-ubiquitins with nanomolar affinity, affording quantitative precipitation. LifeSensors has licensed this novel technology from bioGUNE in Spain.
May 2008
LifeSensors launches a number of De-ubiquitylases and other ubiquitin and ubiquitin-like protein enzymes, as well as a novel assay platform for De-ubiquitylases and UBL isopeptidases, including De-SUMOlyases, De-NEDDylases, and De-ISGinylases.
November 2007
LifeSensors files novel SUMOstar protein expression patent applications worldwide for production of proteins in yeast, insect and mammalian cells, and launches related products.
2006
LifeSensors’s SUMO technologies for protein production are disseminated worldwide by the publication of new data (see publications).
LifeSensors is granted patent in gender sorting technologies by US patent and trademark offices in August, 2006. The estrogen receptor-based sensor is used to sort poultry eggs. This first-of-its-kind technology improves poultry management, increases production and reduces cost.
2005
LifeSensors enters a licensing agreement with Progenra Inc, a ubiquitin drug discovery company, to launch Progenra technologies for research and consumer markets.
2004
LifeSensors files three patent applications covering novel gene-fusion tags. This series of patents further strengthens the company's position in the development of tools for the therapeutic and structural/functional genomics markets.
June 2003
LifeSensors files a patent application for Split-SUMO technology for the enhancement of protein expression and purification in prokaryotic and eukaryotic cells.
January 2000
LifeSensors signs a multi-year agreement with Embrex, Inc. (now part of Pfizer Animal Health) to develop estrogen receptor-based sensors for the poultry gender sorting market.
The Company files a patent application for protein expression and purification technology using ubiquitin-like proteins as expression enhancers and purification tags.
2000
LifeSensors receives several small business innovation research (SBIR) awards from the National Cancer Institute and NIH, NIEHS, and NASA to develop LiveSensors™ and protein expression technologies.
August 1998
LifeSensors Inc. receives an emerging company investment fund award from Ben Franklin Technology Partners of Southeastern Pennsylvania.
April 1998
Protein Expression Services launched. The Company is relocated to state-of-the-art facilities in the Great Valley Corporate Center in Malvern, PA, a western suburb of Philadelphia.
December 1996
The Company establishes a multi-year research collaboration agreement with Rohm and Haas Company.
July 1996
LifeSensors is founded by Dr. Tauseef Butt following 14 year tenure at SmithKline Beecham Pharmaceutical R&D (GlaxoSmithKline Pharmaceuticals).
