piggyBac splinkerette PCR Kit (PB-SPLK-1)

Catalog #: KPB-001

Optimized protocol and verified primers required for identification of piggyBac transposon integration sites.


Production of sufficient quantities of antibody early in the development process to allow for testing in an expanding collection of biological and physicochemical assays is challenging. Transient gene expression in CHO cells allows for the rapid generation of small quantities of material. Although this can be rapid, scaling up to provide gram quantities of material can be prohibitive. Switching to stable gene expression is preferred for generating these large quantities of protein but the generation of clonal CHO cell lines can be both time consuming and labor intensive. More recently stable CHO cell pools have been utilized which can reduce the time to produce protein but may be generally less stable than clonal lines and may also have lower expression titers.

Transposagen has developed a piggyBac transposon system that has been validated for use in the generation of antibodies from CHO cell pools and individual clones. In these collaborative studies, published by Eli Lilly and others, antibody titers as high as 7.6g/L were obtained from a heterogenous CHO cell population. Titers were improved for each of the four antibodies tested in comparison with control pools. On average the fold increase for the three mono-functional antibodies was approximately 4-fold and for the bi-functional antibody tested was nearly 12-fold (specific productivity ranged from 4.2-9.3-fold improvement with the piggyBac pools)2. In addition, the PB system significantly increased the frequency of high titer clone isolation suggesting that the isolation of high producing stable CHO clones could be accelerated. Further studies have shown that the product quality attributes for protein obtained from the piggyBac system are identical to that from standard techniques; the system can be readily adapted to growth in bioreactors (demonstrated at 36L scale) and the PQA are stable over multiple passage (55 generations)3.

Therefore, these data demonstrate that the piggyBac transposon system is superior to standard methods for generation of CHO cell pools and would also make clonal isolation more efficient. Improved protein production and acceleration of clonal CHO cell generation make this system ideal for early development and may reduce the time for entry into the clinic significantly.
