Background Information
TCEB2 encodes the protein elongin B, which is a subunit of the transcription factor B (SIII) complex and is also reported to function as an adapter protein in the proteasomal degradation of target proteins via different E3 ubiquitin ligase complexes (PMID: 26531153). TCEB2 has 2 isoforms with the molecular mass of 13 and 18 kDa.

Reviews
What customers say
Both reviewers gave 5 stars for Western Blot on HEK293T cells using a 1:500 dilution (lot 00001072). One user noted that while bands can appear somewhat diffuse, they are highly specific with no background or off-target signals, calling it the best EloB antibody their lab has tried. The other reported a strong, clean signal when blocking with 5% NFM or 5% BSA in TBST. Overall, users praise its specificity and reliable performance for WB applications.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Anna (Verified Customer) (02-05-2026) | Bands tend to be diffuse but are specific (no background or off-target bands). The best EloB antibody I or anyone in our lab has tried.
