Product Information

The Ubiquitin-Trap Magnetic Agarose Kit is a ready-to-use reagent for the IP of ubiquitin and ubiquitinylated proteins. It consists of an anti-ubiquitin Nanobody/VHH coupled to magnetic agarose beads, along with lysis, wash, and elution buffers to use in the IP process.

DescriptionThe Ubiquitin-Trap Magnetic Agarose Kit contains Ubiquitin-Trap magnetic agarose, lysis, wash, and elution buffers for efficient immunoprecipitation of ubiquitin and ubiqutinylated proteins.

• Fast, reliable & efficient one-step immunoprecipitation

• Ready-to-use

• No heavy & light antibody chains

• Stable under harsh washing conditions

• Suitable for downstream mass spec analysis

• Works in samples from: mammals, plants, yeast, etc.

ApplicationsIP, CoIP
Specificity/TargetBinds to monomeric ubiquitin, ubiquitin chains, and ubiquitinylated proteins. Ubiquitin chains may be linked via lysines; linkages via lysines such as K11, K48 and K63 are compatible with binding by the Ubiquitin-Trap (further linkage types also likely to be compatible, but not tested).
Tested ReactivityHuman, Mouse, Hamster, Dog, Spinach, Yeast
ConjugateMagnetic agarose beads; ~40 um (cross-linked 6% magnetic agarose beads)
Elution buffer2x SDS-sample buffer (Lammli)
Wash Buffer Compatibility2M NaCl, 5 mM DTT, 0 mM β-mercaptoethanol, 5 mM TCEP, 2% NP40, 2% Triton X-100, 0% SDS, 2-3 M Urea
TypeNanobody
ClassRecombinant
HostCamelid
Affinity The KD for monomeric ubiquitin is 90 nM. The apparent affinity is even higher for ubiquitin chains due to avidity effects.
Compatibility with mass spectrometryThe Ubiquitin-Trap is optimized for on-bead digestion. For the application note, please click here: On-bead digest protocol for mass spectrometry
