  • Efficient tool for the selective isolation of ubiquitinylated proteins
  • High binding affinity matrix, able to bind both monoubiquitinated and polyubiquitinated proteins
  • Highly compatible with a wide range of lysate buffer, different sample types (cells, tissues) and a broad range of species
For isolation and enrichment of ubiquitinylated proteins.The UBI-QAPTURE-Q® kit is an efficient tool for the selective isolation of ubiquitinylated proteins. The Kit facilitates the isolation of both mono- and poly-ubiquitinylated proteins (independent of lysine residue chain linkage) from cell extracts, tissue lysates and in vitro assay solutions through use of a high-binding affinity matrix. Captured proteins can be analyzed by Western blotting using the highly sensitive ubiquitin-conjugate specific antibody provided, using antibodies to specific proteins of interest, or eluted from the matrix for subsequent biochemical characterization. The UBI-QAPTURE-Q® matrix supplied with the kit has superior binding characteristics compared to other commercially available matrices and is compatible with a wide range of lysate buffers and cell/tissue samples from a variety of species.
Western blot analysis of ubiquitin enrichment of lysate derived ubiquitinylated proteins. Ubiquitin enrichment experiment set-up and run as described in “Capture/enrichment of ubiquitinylated proteins”. Ubiquitin-protein conjugates present in starting material, unbound fraction and elution fraction were detected by western blotting as described in “Analysis by western blotting”, using the provided ubiquitin-conjugate specific HRP-linked antibody (Prod. No. BML-UW0150) at a dilution of 1:1000 dilution. Capture of Ub-protein conjugates from Control ubiquitinylated-protein lysate (Prod. No. BML-UW0130). Key: SM = Starting Material, UF = Unbound Fraction and EL = Elution Fraction.

Product Specification

Application Notes:Uses:
  1. Isolation and detection of the full range of ubiquitinylated protein conjugates (mono-/multi-/poly-ubiquitin modified, lysine linkage independent) from specific cell/tissue lysates of interest, especially low abundance (regulatory) proteins involved in the ubiquitin-proteasome pathway.
  2. Capture and analysis of specific ubiquitinylated protein conjugates of interest from particular cell/tissue lysates.
  3. Purification/pull down of ubiquitinylated proteins from cell free in vitro assays; for example to isolate Ub-p53 species from ubiquitinylation assays mediated by HeLa S100 lysate (Prod. No. BML-SW8750).
  4. Release of free proteins in their active/native form by cleavage of ubiquitin/ubiquitin chains from the UBI-QAPTURE-Q® matrix using deubiquitinylating enzymes such as USP2 (Prod. No. BML-UW9850).
  5. Release of ubiquitinylated proteins in their active/native form by elution from the UBI-QAPTURE-Q® matrix using, for example, high salt buffer.
