Yes! Rabbit Fabs have a unique disulfide architecture that historically has caused expression problems in E. coli, leading to the development of sub-optimal systems that do not use the full rabbit immune repertoire. However, we are able to bypass this barrier with our RabWizTM platform. Our proprietary phage vector has been highly optimized specifically for rabbit Fabs, allowing us to express the dominant Ckappa1 clones that cause expression problems in traditional phage systems. We have successfully used this platform to develop functional rabbit antibodies for hundreds of targets, including peptide, protein and cell-based antigens.
