Ubiquitin Research Tools

Interactive Ubiquitin Product Selector

The reversible conjugation of ubiquitin and ubiquitin-like proteins to substrates regulates a large number of cellular processes. Deciphering these complex pathways is the focus of many researchers but the work has been slowed by the lack of high quality research tools. LifeSensors has the largest collection of ubiquitin research tools commercially available for studying the enzymes involved in this complex pathway. Using these tools scientists will be able to characterize enzyme function, identify substrates, discover modulators of this pathway and make scientific breakthroughs that will deepen our understanding of the ubiquitin pathway.

Ubiquitin Affinity Matrices (TUBEs)

The study of ubiquitylated proteins is complicated by the fact that these modified substrates are not stable either in cells or in vitro. In order to aid researchers in the purification and identification of ubiquitylated proteins LifeSensors licensed the TUBE (Tandem ubiquitin binding entity) technology from CICBioGUNE. TUBEs have a superior affinity for poly-ubiquitin chains compared to traditional ubiquitin binding domains (up to 1000-fold increase in affinity). These TUBEs can be used to both stabilize poly-ubiquitin chains and purify ubiquitylated proteins making them a valuable addition to the ubiquitin researcher’s toolbox.

Ubiquitin/Conjugation Assays

The conjugation of ubiquitin to substrates is a multi-step, multi-enzyme process. LifeSensors is committed to developing high throughput, facile, and robust assays for measuring the activity of ubiquitin conjugating enzymes. LifeSensors has recently developed a microtiter plate-based assay for measuring protein ubiquitylation. This assay is amenable to high throughput screening and works with a wide range of E3 ligases including members of the three major classes of E3 ligases (simple RING class, SCF RING class, and HECT class)

Ubiquitin/Ubl Conjugating Enzymes

Ubiquitin/Ubl conjugating enzymes are responsible for the selective modification of substrates. LifeSensors supplies a wide assortment of these enzymes to aid researchers in their efforts to understand the specificity and selectivity of this complex enzyme pathway.

Expression Systems

Isopeptidase Assays

Ubiquitin and ubiquitin-like isopeptidases play key regulatory roles in a variety of disease states including cancer, diabetes, and infectious disease. As such they represent an attractive class of novel targets for therapeutic development. In addition although close to 100 Ub/Ubl isopeptidases have been identified by bioinformatic analysis of the human genome relatively few of these have been characterized. LifeSensors offers a wide range of assays for characterizing the activity of these proteases and these assays are amenable to high throughput screening for modulators of their activity.

Ubiquitin/Ubl Isopeptidases

LifeSensors has the largest collection of deubiquitylases commercially available. These enzymes can be utilized for high throughput screening or determining which enzymes recognize a given ubiquitylated substrate.

Expression Systems

Ubl-Pathway Inhibitors

LifeSensors offers a large number of ubiquitin/ubiquitin-like isopeptidase inhibitors. Along with classical inhibitors such as ubiquitin-vinyl methyl ester and –vinyl sulfone, LifeSensors has an evergrowing number of small molecule inhibitors of Ub/Ubl isopeptidases including PR-619. The use of these inhibitors to block protease function enables scientists to decipher the function of ubiquitylated substrates.
Expression Systems

Isopeptidase Substrates

In addition to the high throughput assays LifeSensors markets for measuring Ub/Ubl isopeptidase activity we also supply many enzyme substrates that can be utilized for in vitro experiments.

Expression Systems

Antibodies

Antibodies can be used in a wide range of applications including Western blotting, ELISA assays, immunofluorescence and immunoprecipitation. Often the existence of a quality antibody recognizing the protein of interest is the most useful reagent to the bench scientist in their efforts to uncover novel protein functions. LifeSensors offers quality antibodies recognizing many of the enzymes involved in protein ubiquitylation to aid researchers in their quest.


Expression Systems

Dub Chip

The world's most versatile and informative microarray, dedicated to the deconjugation side of the ubiquitin (and Ubl) pathways(s). Select one of three application protocols for use with either DUB proteins, DUB antibodies, or catalytically active DUB enzymes. Identify DUBs for proteins of interest, discover biomarkers, or screen DUB inhibitors in a multiplexed fashion. (Coming Soon!)

LifeSensors Launches DiUbiquitin Substrate
A Novel Fluorescent Assay for Ubiquitin Isopeptide Bond Cleavage
MALVERN, PA -- June 29, 2010 --LifeSensors, Inc., a biotechnology company, announces the launch of its novel physiologically relevant diubiquitin substrates for measuring isopeptide bond cleavage (patent applied for). This breakthrough technology, for both basic research and drug discovery targeting the ubiquitin proteasome pathway, offers sensitive, rapid, and robust fluorescent readouts of isopeptidase or de-ubquitylase (DUB) activity.

LifeSensors' Gender Sorting Technology Discussed
Feb 9th 2010 | From The Economist online
Dr Butt’s new device is an oestrogen sniffer. It relies on the fact that female embryos produce this hormone in quantity and male ones do not. The sensor uses a fine needle to penetrate both the shell and the allantoic sac of an egg. This sac is a fluid-filled membrane that cushions the embryo and helps it trade carbon dioxide for oxygen from the air. (It is also the membrane that can make peeling a hard-boiled egg such a frustrating affair.)

An estrogen sensor for poultry gender sorting.

Tran HT, Ferrell W, Butt TR.

The need for segregation of poultry based on sex is driven by gender-related differences in growth rate, market age, management practices, and nutritional requirements. Each day, global poultry industry staff would ideally like to determine the gender of >150 million newly hatched birds. Currently, this can be done only manually at the hatchery, which is a virtually impossible undertaking. LifeSensors has developed a facile, rapid, and low cost yeast-based assay that distinguishes male from female embryonated eggs before hatching based on the estrogen level of their allantoic fluid.
