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 in HEK293 cells. Individual clones are screened to select the best candidates for production.
Advantages include:
- Improved specificity and sensitivity
- Lot-to-lot consistency
- Animal origin-free formulation
- Broader immunoreactivity due to the larger rabbit immune repertoire
Target Information
Periostin (PN), also known as osteoblast-specific factor 2 (OSF-2), is a disulfide-linked, secreted protein that binds heparin and functions as a ligand for αVβ3 and αVβ5 integrins. It acts as a cell adhesion molecule in preosteoblasts and plays a role in osteoblast recruitment, spreading, and attachment.
Periostin is mainly detected in the lower gastrointestinal tract, aorta, stomach, placenta, uterus, and breast tissues, but is up-regulated in epithelial ovarian tumors and overexpressed in breast cancer. Its expression is induced by BMP2 and TGF-β1. The protein contains a signal sequence, a cysteine-rich domain, four fasciclin-like repeats, and a C-terminal domain.
