Description	UBI trap-B are used to isolate and identify ubiquitylated proteins from cells, tissues or organs. Multiple ubiquitin binding domains (UBDs) contribute to enhance their affinity for polyubiquitin chains compared to single UBDs. (1-3). Prototype UBI traps interfere with the action of de-ubiquitylating enzymes (DUBs) and the proteasome which contribute to increase the yield of ubiquitylated proteins purified and facilitate the detection of low abundance proteins. These unique properties are not observed with any other technologies that can be used in a large panel of applications (3). UBI trap-B is based on UBDs with preference for K63 linked polyubiquitin chains but other chains can also be captured (1-3). Furthermore, differences can be observed depending on the relative chain abundance in distinct cell lines and response to various treatments. GST control is provided for a single control reaction.
Molecular Weight	55, 647 kDa
Solubility	>30 mg/mL
Concentration	Variable (5-10 mg/mL)
Storage	-80°C, avoid freeze/thaw cycles
Applications info	Pull down of poly-ubiquitylated proteins from cell and tissue lysates using glutathione beads. Captured proteins can be analyzed by Western blot or Mass spectrometry with the appropriate adaptations. Protection of poly-ubiquitylated proteins from both deubiquitylation and degradation by the proteasome Quantitative or semiquantitative methods using different supports.
Benefits	Up to 1000-fold higher affinity than the single UBD Avoid overexpression of tagged ubiquitin for pull downs Protect poly-ubiquitin chains without inhibitors specific to the proteasome or DUBs activity Replace ubiquitin specific antibodies for enrichment of poly-ubiquitylated proteins
Examples of use	UBI trap-B can be used to detect ubiquitylated cellular factors implicated in the regulation of signaling pathways regulating inflammation, oncogenesis, neurodegenerative diseases and multiple infections (4-8). The ubiquitylated status of these factors can be followed in response to a treatment and determine if cells are responding well (9-10). The ubiquitylation of crucial cellular factors can also be followed after infection with various microorganisms (11). Among other examples. A UBI traps step by step protocol has also been reported (12).
Information	High affinity (nM range) with binding preference for K63 Ub chains
Storage	-80°C, avoid freeze/thaw cycles
Additional Info	More size options available from 200ug up, please inquire
Format	Flexible on 0, 5mg / 1mg or more
