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

Target description

Protein FosB (UniProt: P53539; also known as FosB proto-oncogene AP-1 transcription factor subunit, G0/G1 switch regulatory protein 3, Transcription factor AP-1 subunit FosB) is encoded by the FOSB (also known as G0S3) gene (Gene ID: 2354) in human.  FosB is a member of the Fos family of transcription factors that is shown to accumulate in a subset of neurons of the nucleus accumbens and dorsal striatum following repeated administration of drugs of abuse. It persists in neurons for LONG^® periods of  time due to its high stability. The genic expression of FosB seems to be modified after LONG^® time exposure to drugs of abuse and these changes may be involved in craving and addicted behavior. The FosB protein exhibits a truncated and stable splicing variant known as ΔFosB, whose accumulation is critical for the establishment of addictive behavior. FosB heterodimerizes with proteins of the Jun family to form an AP-1 transcription factor complex, thereby enhancing their DNA binding activity to gene promoters containing an AP-1 consensus sequence 5′-TGA[GC]TCA-3′. Together with Jun, it also plays a role in activation-induced cell death of T cells by binding to the AP-1 promoter site of Fas ligand (CD95L) and inducing its transcription in response to activation of the TCR/CD3 signaling pathway.  Recurrent rearrangement of Fos and FosB are observed in the most common benign tumors of bone, osteoblastoma, and osteoid osteoma. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity^™, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstitution

300 µg/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.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
