Clone Host Grade Applications
Monoclonal Rabbit Affinity Purified B IP IH IC FC
Polyubiquitin chains linked from the Lys48 of one protein to the C-terminus of the other are the most common ubiquitin linkage. Lys48- linked ubiquitins are abundant in vivo and act as a universal signal for proteins targeted for proteosomal degradation.
Catalog #U1000-06P
ApplicationsSuitable for use in Flow Cytometry, Western Blot, Immunoprecipitation, Immunohistochemistry, Peptide Inhibition Assay and Immunocytochemistry. Other applications not tested.
Recommended DilutionsFlow Cytometry: 1:700 permeabilized Jurkat cells
Western Blot: 1:1000-1:5000
Immunoprecipitation: 10ul/100ug HeLa cell lysate
Immunohistochemistry: 1:100. Formalin fixed sections were heated in citrate buffer, pH 6.
Peptide Inhibition Assay: 1:1000 dilution with K48-multiubiquitin chains inhibited binding to HeLa cell lysate.
Immunocytochemistry: 1:500
Optimal dilutions to be determined by the researcher.
