Human Bax ELISA Kit ab199080 is a rapid single-wash 90-min Sandwich ELISA to measure Human Bax in cell culture extracts, tissue extracts. This SimpleStep sensitivity is 2.2 pg/mL.
How the assay works
Human Bax SimpleStep ELISA
employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA
plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA
protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA
kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Bax is a pro-apoptotic factor of Bcl-2 family. It accelerates programmed cell death by binding to, and antagonizing the apoptosis repressor BCL2 or its adenovirus homolog E1B 19k protein. Under stress conditions, Bax undergoes a conformation change that causes translocation to the mitochondrion membrane, leading to the release of cytochrome c that then triggers apoptosis. Bax promotes activation of CASP3, and thereby apoptosis. Under a normal conditions, Bax colocalizes with 14-3-3 proteins in the cytoplasm. Under stress conditions, Bax undergoes a conformation change that causes release from JNK-phosphorylated 14-3-3 proteins and translocation to the mitochondrion membrane. Bax forms higher oligomers under stress conditions. Bax interacts with BCL2L11. The interaction with BCL2L11 promotes BAX oligomerization and association with mitochondrial membranes, with subsequent release of cytochrome c. Bax forms heterodimers with BCL2, E1B 19K protein, BCL2L1 isoform Bcl-X(L), BCL2L2, MCL1 and A1. Bax interacts with SH3GLB1 and HN. Bax interacts with SFN and YWHAZ; the interaction occurs in the cytoplasm. Under stress conditions, JNK-mediated phosphorylation of SFN and YWHAZ, releases BAX to mitochondria. Bax isoform Sigma interacts with BCL2A1 and BCL2L1 isoform Bcl-X(L). Bax interacts with RNF144B, which regulates the ubiquitin-dependent stability of BAX. Bax interacts with CLU under stress conditions that cause a conformation change leading to BAX oligomerization and association with mitochondria. Bax does not interact with CLU in unstressed cells. Bax interacts with FAIM2/LFG2. Bax interacts with human cytomegalovirus/HHV-5 protein vMIA/UL37. Bax interacts with BOP/C22orf29.

Bax also known as Bcl-2-associated X protein plays an important role in the regulation of apoptosis. It is widely known for its pro-apoptotic function opposing the action of anti-apoptotic proteins like Bcl-2. Bax has a molecular weight of approximately 21 kDa making it identifiable in laboratory techniques such as western blot. Researchers often use anti-Bax antibodies to detect and analyze its expression levels in various studies. The Bax protein is mainly expressed in mitochondria where it undergoes changes in response to apoptotic signals.
Biological function summary
The Bax protein forms homodimers or heterodimers with other Bcl-2 family proteins to facilitate apoptosis. This protein is part of a larger complex involving several members of the Bcl-2 family which finely tunes the balance between cell survival and programmed cell death. Through a change in its conformation Bax translocates to the outer mitochondrial membrane where it promotes the release of cytochrome c and other apoptogenic factors into the cytosol.
Pathways
Bax plays a significant role in the intrinsic pathway of apoptosis also known as the mitochondrial pathway. This pathway involves the release of cytochrome c which further activates downstream proteins such as caspase-9 and caspase-3. Bax interacts closely with proteins like Bak another pro-apoptotic member of the Bcl-2 family providing a cooperative function in mitochondrial membrane permeabilization. Together Bax and Bak act as gatekeepers of the mitochondrial pathway determining the cell's fate in response to apoptotic stimuli.
The dysregulation of Bax often associates with various cancers and neurodegenerative diseases. In cancer reduced Bax expression or function can lead to resistance to apoptosis contributing to unchecked cellular proliferation. Conversely in neurodegenerative disorders such as Alzheimer's disease increased Bax activity results in excessive neuronal apoptosis. The balance between Bax and its partner proteins like Bcl-2 or Bcl-xL is important in maintaining normal cellular function and preventing disease progression.
