    CHO Cells & Transgenic Rabbits


The traditional CHO antibody production and animal bioproduction methods are inefficient because they require random gene insertion and forced amplification of transgenes. Applied StemCell has addressed these problems by utilizing our expertise in cell line and animal model engineering with our proprietary TARGATT™ technology to develop two bioproduction methods: TARGATT™ CHO Master Cell Lines and Transgenic TARGATT™ Rabbits. Both methods offer low-cost, efficiency, consistent protein expression and high protein yield that is easily scalable for large scale bioproduction.
