Product Specific Information
Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems. These systems clone specific antibody DNA sequences from immunoreactive rabbits, followed by screening to select optimal clones for production.
Advantages include:
- Improved specificity and sensitivity
- Lot-to-lot consistency
- Animal origin-free formulations
- Broader immunoreactivity due to the extensive rabbit immune repertoire
Target Information
CEA (Carcinoembryonic Antigen, CD66e) is expressed during fetal gut development and re-expressed in various carcinomas. It belongs to the immunoglobulin superfamily, containing one N domain and six immunoglobulin constant-like domains (A1, A2, A3, B1, B2, B3).
Antibodies against CEA are useful in:
- Identifying origins of metastatic adenocarcinomas
- Differentiating pulmonary adenocarcinomas (CEA+) from pleural mesotheliomas (rarely or weakly CEA+)
CEA functions as a cell adhesion molecule and is implicated in:
- Tissue differentiation and 3D structure organization
- Angiogenesis, apoptosis, tumor suppression, and metastasis
- Modulation of innate and adaptive immune responses
Multiple transcript variants exist, though not all full-length forms are defined.
