Flow Cytometry analysis of HEL cells using anti-UBE4B antibody (A04338-1).
Overlay histogram showing HEL cells stained with A04338-1 (Blue line). To facilitate intracellular staining, cells were fixed with 4% paraformaldehyde and permeabilized with permeabilization buffer. The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-UBE4B Antibody (A04338-1, 1 μg/1x106 cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-rabbit IgG (BA1127, 5-10 μg/1x106 cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG (1 μg/1x106) used under the same conditions. Unlabelled sample without incubation with primary antibody and secondary antibody (Red line) was used as a blank control.

Background of UBE4B
The modification of proteins with ubiquitin is an important cellular mechanism for targeting abnormal or short-lived proteins for degradation. Ubiquitination involves at least three classes of enzymes: ubiquitin-activating enzymes, or E1s, ubiquitin-conjugating enzymes, or E2s, and ubiquitin-protein ligases, or E3s. This gene encodes an additional conjugation factor, E4, which is involved in multiubiquitin chain assembly. This gene is also the strongest candidate in the neuroblastoma tumor suppressor genes. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

Antibody Homology Across Species
The results generated by this homology analysis tool for commonly used animal species are shown below. For unlisted species, please refer to the homology analysis between the immunogen sequence and the corresponding species.
A homology of ≥90% is recommended. Generally, higher homology indicates a greater potential for cross-species reactivity. However, protein expression levels may vary among different species, tissues, and cell types. Therefore, the homology analysis results are for reference only and do not guarantee antibody cross-reactivity or experimental performance.
