Western blot analysis of extracts from Hela(lane 2(20ug) and Hela(lane 3(40ug) using Bak Antibody (HY-P80563) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.

Immunocytochemistry analysis of Hela cells labeling Bak with Bak Antibody (HY-P80563)at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with Bak Antibody (HY-P80563) at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Staining at 4 ℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L(HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Immunohistochemical analysis of paraffin-embedded mouse heart tissue using Bak Antibody. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/100 dilution in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background

Function
Bak (BCL-2 homologous antagonist/killer) is a pro-apoptotic Bcl-2 family effector that executes intrinsic apoptosis by permeabilizing the mitochondrial outer membrane together with Bax[1]. Mechanistically, Bak activation enables mitochondrial outer membrane permeabilization, cytochrome c release, caspase activation, and apoptotic cell death[2]. In cancer-related models, dysregulated Bcl-2 family signaling supports apoptosis evasion, while Bak/Bax-dependent mitochondrial permeabilization remains a central checkpoint for therapeutic apoptosis induction[3]. Compared with Bax, Bak shows distinct regulatory behavior inside living cells, because Bcl-2 family interactome analysis indicates differences in Bax and Bak activation by anti-apoptotic and BH3-only proteins[4]. Bak also differs from Bax in mitochondrial targeting biology, since VDAC2 brings both effectors to mitochondria and forms a defined VDAC2-Bak complex that can modulate Bak apoptotic activity[1]. For experimental applications, large unilamellar vesicles provide a tractable biochemical model to test Bcl-2 family protein combinations and real-time membrane permeabilization by Bak/Bax-centered mechanisms[2]. Pharmacologically, interfaces regulating Bak activity may be targeted to inhibit excessive Bak-mediated apoptosis or promote Bak-mediated apoptosis for cancer therapy[1]. Small-molecule or peptide strategies that modulate Bcl-2 family interactions therefore remain practical tools for studying Bak-dependent mitochondrial apoptosis[3][2].
