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.

Specificity

Clone 3I14 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects Chromobox protein homolog 2 (CBX2). It targets an epitope within 25 amino acids from the N-terminal region.

Immunogen

KLH-conjugated linear peptide corresponding to 25 amino acids from the N-terminal region of human Chromobox protein homolog 2 (CBX2).

Application

Quality Control Testing

Evaluated by Western Blotting in HEK293 cell nuclear extract.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected CBX2 in HEK293 cell nuclear extract.

Tested Applications

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected CBX2 in nuclear extract from NIH3T3 cells, HeLa cells, and L6 cells.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected CBX2 in HeLa, A431, HepG2, and NIH 3T3 cells.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected CBX2 in human skin tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound CBX2 peptide with a KD of 8.7 x 10-7 in an affinity binding assay.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-CBX2, clone 3I14 ZooMAb®, Cat. No. ZRB1084, is a recombinant Rabbit monoclonal antibody that specifically targets CBX2 and is tested for use in Affinity Binding Assay, Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.

Target description

Chromobox protein homolog 2 (UniProt: Q14781; also known as CBX2) is encoded by the CBX gene (Gene ID: 84733) in human. CBX2 is a component of a Polycomb group (PcG) multiprotein PRC1-like complex that is expressed during interphase and metaphase. It plays a role in the lineage differentiation of the germ layers in embryonic development and is involved in sexual development, acting as activator of NR5A1 expression. It is shown to be localized in distinct foci on chromatin and in chromocenters. CBX2 is reported to be expressed from week 9 to week 25 post-fertilization in both male and female gonads. It is required to maintain the transcriptionally repressive state of many genes throughout development via chromatin remodeling and modification of histones. Disruption of this gene in murine models is shown to result in male-to-female gonadal sex reversal. Levels of CBX2 are reported to decrease in macrophages upon viral infection and knockdown of CBX2 gene in macrophages can inhibit virus-induced production of interferon-. CBX2 is reported to bind and recruit Lysine demethylase 6B (Jmjd3) to the IFN- promoter, leading to demethylation of H3K27me3 and increased transcription of IFN-β. Mutations in CBX2 gene are associated with gonadal dysgenesis in humans. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
