| 20090220470 | UBIQUITIN BINDING POLYPEPTIDES - The invention relates to Tandem Ubiquitin Affinity Entities (TUBES) which are fusion polypeptides comprising at least two ubiquitin binding domains connected to each other by non-naturally occurring spacer regions. The TUBES are capable of binding with high affinity to ubiquitin and to ubiquitylated polypeptides and are therefore suitable for the purification of ubiquitylated polypeptides from cellular extracts as well as for the identification of new ubiquitylated polypeptides. | 09-03-2009 |
