Background Information
SETDB1, also named as ESET, KIAA0067 and KMT1E, belongs to the histone-lysine methyltransferase family. It is a SET domain protein with histone H3-K9-specific methyltransferase activity. H3 'Lys-9' trimethylation is coordinated with DNA methylation and represents a specific tag for epigenetic transcriptional repression by recruiting HP1 (CBX1, CBX3 and/or CBX5) proteins to methylated histones. SETDB1 mainly functions in euchromatin regions, thereby playing a central role in the silencing of euchromatic genes. It probably forms a complex with MBD1 and ATF7IP that represses transcription and couples DNA methylation and histone 'Lys-9' trimethylation. Its activity is dependent on MBD1 and is heritably maintained through DNA replication by being recruited by CAF-1. SETDB1 regulates histone methylation, gene silencing, and transcriptional repression. It has been identified as a target for treatment in Huntington Disease, given that gene silencing and transcription dysfunction likely play a role in the disease pathogenesis. This antibody is a rabbit polyclonal antibody raised against residues near the N terminus of human SETDB1.The calculated molecular weight of SETDB1 is 143 kDa, but the modified SETDB1 protein is about 170 kDa (PMID: 11791185).

Reviews
What customers say
Users report that this SETDB1 antibody performs well for Western Blot across multiple cell types including Jurkat, HeLa, and T cells, typically at 1:1000–1:2000 dilution with overnight incubation at 4°C. One reviewer also confirmed its utility for ChIP, noting good binding at 2 µg. Overall, the antibody produces distinct target bands with minimal nonspecific background, though some variability was observed depending on the cell type used. Average rating is 4.7 out of 5.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Hilda (Verified Customer) (07-29-2024) | SETDB1 antibody works very well with human and mouse cell lines for both western blot and ChIP. It requires a short incubation period and produces distinct bands, with a few nonspecific bands observed variable to the type of cells used. CHIP outcomes are still preliminary, but it has resulted in good binding at 2ug antibody used.
