SpecificityThe specificity of this antibody has been confirmed by WB and IHC against the antigen. Zebrafish; Human; Rat;
Species ReactivityHuman, Rat, Zebra Fish
Immunogen DescriptionA synthetic peptide (DRDYMERDKENPNQYNYIA) corresponding to a region (877-895) from the C-terminus of human Cullin-4B. To enhance the immunological response, this peptide was coupled to carrier protein BSA.
ConjugateUnconjugated
Purity DescriptionAffinity purified on antigen column
Application DetailsWestern Blotting (WB) and Immunohistochemistry (IHC). A concentration of 1.0 µg/mL is recommended for WB. Human Cullin-4B (isoform 1) has a predicted length of 895 residues and MW of 102 kDa. A concentration of 2.0 µg/mL is recommended for IHC in Zebra fish. Heat mediated antigen retrieval is recommended. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Reconstitution InstructionsSpin vial briefly before opening. Reconstitute in 100 µL sterile-filtered, ultrapure water to achieve an antibody concentration of 1 mg/mL. Centrifuge to remove any insoluble material.
Storage InstructionsAt least 12 months after purchase at 2-8°C (lyophilized formulations). After reconstitution, aliquot and store at -20°C for a higher stability. Avoid freeze-thaw cycles.
Batch NumberPlease see item label.
Expiration Date12 months after date of receipt (unopened vial).
Scientific BackgroundCullin-4B is a core component of E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of specific proteins in the cell.
