Specificity/Sensitivity

BACH1 (E4E7B) Rabbit Monoclonal Antibody recognizes endogenous levels of total BACH1 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the central region of human BACH1 protein.

Background

BTB and CNC homology 1 (BACH1) is a basic leucine zipper transcription factor that is widely expressed in mammalian tissues (1). Through its roles in both transcriptional activation and repression, BACH1 regulates a wide range of cellular processes, including senescence, heme homeostasis, oxidative stress response, and the cell cycle (2-5). In competition with NRF2, BACH1 regulates ferroptosis; BACH1 promotes the process while NRF2 inhibits it (6,7). BACH1 heterodimerizes with Maf proteins (8). These heterodimers bind to Maf recognition elements at the promoters of oxidative stress response genes, such as heme oxygenase-1 (HMOX1) and NAD(P)H:quinone oxidoreductase 1 (NQO1) (9,10). As a transcriptional repressor, BACH1 recruits nuclear receptor corepressor 1 (NCoR1) as well as histone deacetylase 1 (HDAC1) (3). BACH1 has recently been implicated as a driver of cancer metastasis and is a potential therapeutic target in breast and lung cancer (11-13).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

Simple Western™ analysis of lysates (0.1 mg/mL) from HEL 92.1.7 cells using BACH1 (E4E7B) Rabbit mAb #33059. The virtual lane view (left) shows the target band (as indicated) at 1:10 and 1:50 dilutions of primary antibody. The corresponding electropherogram view (right) plots chemiluminescence by molecular weight along the capillary at 1:10 (blue line) and 1:50 (green line) dilutions of primary antibody. This experiment was performed under reducing conditions on the Jess™ Simple Western instrument from ProteinSimple, a BioTechne brand, using the 12-230 kDa separation module.
