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 3B22 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects Proliferating cell nuclear antigen (PCNA). It targets an epitope within the first 150 amino acids.

Immunogen

GST/His-tagged recombinant fragment corresponding to the first 150 amino acids from the N-terminal region of human Proliferating cell nuclear antigen (PCNA).

Application

Anti-PCNA, clone 3B22 ZooMAb, Cat. No. ZRB1442, is a recombinant Rabbit monoclonal antibody that specifically targets PCNA and is tested for in Affinity Binding Assay, Immunocytochemistry, Immunohistochemistry, and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected PCNA in HeLa cell lysate.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected PCNA in HeLa, A431, HUVEC cell lines.

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

Affinity Binding Assay: A representative lot of this antibody bound recombinant PCNA with a KD of 2.0 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

Target description

Proliferating cell nuclear antigen (UniProt: P12004; alsoknown as PCNA) is encoded by the PCN gene (Gene ID: 5111) in human. PCNA is a homotrimeric nuclear protein thatserves as an auxiliary protein of DNA polymerase delta and is involved in thecontrol of eukaryotic DNA replication by increasing the polymerase′sprocessability during elongation of the leading strand. It Induces a robuststimulatory effect on the 3′-5′ exonuclease and 3′-phosphodiesterase, but notapurinic-apyrimidinic (AP) endonuclease, APEX2 activities. It is reported tocolocalize with CREBBP, EP300 and POLD1 to sites of DNA damage. It acts as aloading platform to recruit DDR proteins that allow completion of DNAreplication after DNA damage and promote post-replication repair. PCNA canundergo phosphorylation on tyrosine 211 by EGFR that stabilizeschromatin-associated PCNA. Following DNA damage, it can undergomonoubiquitination to stimulate direct bypass of DNA lesions by specialized DNApolymerases or polyubiquitination to promote recombination-dependent DNAsynthesis across DNA lesions by template switching mechanisms. Mutation in PCN gene are known to causeAtaxia-telangiectasia-like disorder 2 (ATLD2) that is characterized bydevelopmental delay, ataxia, hearing loss, and short stature. This ZooMAb® recombinant monoclonal antibody, generated by our proprietary technology,offers significantly enhanced specificity, affinity, reproducibility, andstability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in lyophilized from PBS with 5% Trehalose, normal appearance a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitution

0.3 mg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
