ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Target description

CCAAT/enhancer-binding protein alpha (UniProt: P49715; also known as C/EBP alpha, C-EBP alpha) is encoded by the CEBPA (also known as CEBP) gene in human. C-EBP alpha belong to the bZIP family of proteins that serves as a transcription factor that coordinates proliferation arrest and the differentiation of myeloid progenitors, adipocytes, hepatocytes, and cells of the lung and the placenta. It binds directly to the consensus DNA sequence 5′-T[TG]NNGNAA[TG]-3′ acting as an activator on distinct target genes. It can bind DNA as a homodimer or as a stable heterodimer with CEBPB, CEBPD, CEBPE, and CEBPG. It is reported to be essential for the transition from common myeloid progenitors (CMP) to granulocyte/monocyte progenitors (GMP) and has also been shown to be critical for the proper development of the liver and the lung and for terminal adipocyte differentiation. C-EBP alpha down-regulates the expression of genes that maintain cells in an undifferentiated and proliferative state through E2F1 repression, which is critical for its ability to induce adipocyte and granulocyte terminal differentiation. It can be phosphorylated on multiple sites. Phosphorylation at serine 190 is shown to be essential for its interaction with CDK2, CDK4 and SWI/SNF complex leading to cell cycle inhibition. Phosphorylation at threonine 226 and threonine 230 by GSK3 is constitutive in adipose and lung tissue and these sites are also shown to be phosphorylated in liver during feeding, but not during fasting cycle. Four isoforms of C-EBP alpha have been described that are produced by alternative splicing. Mutations in CEBPA gene are known to cause acute myelogenous leukemia (AML). This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
