Product Specific Information
Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems. The antibody DNA sequences from immunoreactive rabbits are cloned and expressed, and the best clones are selected for production.
Advantages include:
- Improved specificity and sensitivity
- Lot-to-lot consistency
- Animal origin-free formulation
- Broader immunoreactivity due to the rabbit immune repertoire
Target Information
Cytokeratins are a subfamily of intermediate filament proteins with high biochemical diversity, represented by at least 20 different polypeptides in human epithelial tissues.
They range in molecular weight from approximately 40 kDa to 68 kDa and have isoelectric points between pH 4.9–7.8.
Cytokeratin expression patterns are characteristic of epithelial type and differentiation stage, making them valuable for distinguishing epithelial malignancies.
Cytokeratin antibodies are useful in:
- Differential diagnosis of tumors via immunohistochemistry
- Cytopathology and flow cytometry assays
For Research Use Only. Not for use in diagnostic procedures. Not for resale without express authorization.
