CBX4 Antibodies

AND CBX4 ELISA kits, CBX4 Proteins

Many biological assays use antibodies to detect CBX4, such as Western Blot (WB), ELISA, Flow Cytometry, Immunocytochemistry (IHC). These antibodies can be polyclonal or monoclonal, and react with CBX4 in Human, Mouse, Rat, and many other animal samples. Boster Bio use mainly mouse and rabbit to develop CBX4 antibodies...

We validate the specificity of these antibodies to CBX4 by testing them on tissues known to express CBX4 positively and negatively. Browse below to find the CBX4 antibody that suites your experiment. We have 2 of these antibodies and many publications and validation images.

If you cannot find antibodies that fit your needs, contact us for making custom antibodies. We have a full suite of custom antibody services covering from research to diagnostic and therapeutic applications.

Designing a Western blot for CBX4? The guide has the expected band size, antibodies backed by real blot images, the controls to run alongside, and protocols taken from published papers.

CBX4 Overview

Facts about E3 SUMO-protein ligase CBX4.

CBX4 3D structure. Source: alphafold

E3 SUMO-protein ligase CBX4 (CBX4)

E3 SUMO-protein ligase which eases SUMO1 conjugation by UBE2I (PubMed:12679040). Involved in the sumoylation of HNRNPK, a p53/TP53 transcriptional coactivator, hence indirectly regulates p53/TP53 transcriptional activation leading to p21/CDKN1A expression.

Monosumoylates ZNF131 (PubMed:22825850). .
