Specificity

Clone 4L5 ZooMAb is a rabbit recombinant monoclonal antibody that specifically detects Brain-specific homeobox/POU domain protein 3A, (Brn-3a).

Immunogen

KLH-conjugted linear peptide corresponding to 19 amino acids from the internal region of human homeobox/POU domain protein 3A (Brn-3a).

Application

Anti-Brn3a, clone 4L5 ZooMAb , Cat. No. ZRB1098, is a highly specific rabbit recombinant monoclonal antibody antibody that targets Brn-3a and has been tested for use in Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.

Western Blotting Analysis: 1:1,000-1:10,000 from a representative lot detected Brn3a in mouse and rat brain tissue lysates

Immunocytochemistry Analysis: A 1:40 dilution from a representative lot detected Brn3a in Neuro2A cell line.

Immunohistochemistry (Paraffin) Analysis: A 1:10,000 dilution from a representative lot detected Brn3a in human and mouse retina tissue sections.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Target description

POU domain, class 4, transcription factor 1 (UniProt: Q01851; also known as Brain-specific homeobox/POU domain protein 3A, Brain-3A, Brn-3A, Homeobox/POU domain protein RDC-1, Oct-T1) is encoded by the POU4F1 (also known as BRN3A, RDC1) gene (Gene ID: 5457) in human. Brn-3A is a multifunctional transcription factor with different regions mediating its different effects. It regulates the expression of specific genes involved in differentiation and survival within a subset of neuronal lineages. It is expressed in the brain and the retina and is present in the developing brain, spinal cord and eye. Its expression peaks early in embryogenesis and is undetectable 14 days after birth. Its C-terminal domain can act as both DNA-binding domain and a transcriptional activator. The N-terminal domain is also required for transactivation activity on some target genes acting as a discrete activation domain. Brn-3A acts by binding to sequences related to the consensus octamer motif 5′-ATGCAAAT-3′ in the regulatory regions of its target genes. The POU-specific domain of Brn-3A is localized to amino acids 261-338. Brn-3A is shown to activate Bcl-2 expression and protect neuronal cells from apoptosis. Two isoforms of Brn-3A have been described that are produced by alternative splicing. Isoform 2 can act as a transcription factor but cannot regulate the expression of the same subset of genes and does not have any anti-apoptotic effect on neuronal cells. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
