Product Information
Kit for IP/Co-IP of ubiquitin and ubiquitylated proteins and sample preparations for mass spectrometry (MS)
| Description | The iST Ubiquitin-Trap Kit enables researchers to process ubiquitinylated proteins and their interacting partners for mass spectrometry analysis by including the ChromoTek Ubiquitin-Trap for IP /Co-IP of ubiqiutinylated proteins and the PreOmics iST buffers and cartridges required for bottom-up proteomic sample preparation. This robust method yields purified peptides while dramatically reducing contamination and sample loss. Each kit accomodates up to eight samples and includes pull-down material for 2 controls. |
| Applications | IP, Co-IP, MS |
| Specificity/Target | Binds 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). |
| Conjugate | Agarose beads; ~90 um (cross-linked 4% agarose beads) |
| Type | Nanobody |
| Class | Recombinant |
| Host | Camelid |
| Affinity (KD) | 90 nM for monomeric ubiquitin. The apparent affinity is even higher for ubiquitin chains due to avidity effects. |
| Compatibility with mass spectrometry | The Ubiquitin-Trap is optimized for on-bead digestion. |
| Storage Buffer | 20% ethanol |
| Storage Condition | Shipped at ambient temperature. Upon receipt store Ubiquitin-Trap at +4°C and Digest at -20°C. |
