Features of YBIRD

YBIRD consists of the GMP controlled facility (745m²) and the Manufacturing Technology Research Laboratory(MTRL)(130m²). The GMP controlled facility is a pilot-scale manufacturing facility for manufacturing of non-sterile investigational drug substances. We also run non-GMP grade pilot-scale manufacturing. Process development, bench-scale sample preparation, and any other bench-scale experiments are performed in MTRL. We handle mammalian cells and microbial cells in separated areas to protect contamination both in the GMP controlled facility and in MTRL.


manufacturing of recombinant proteins both with mammalian cells and with microbial cells

Special feature

In the GMP controlled facility, cross contamination risks are minimized by separating the two areas by the waste transfer hallway, non-sharing apparatuses in both upstream and downstream processes, and controlling air current.


maximum culture volume is 200L for microbial cell lines, 500L for mammalian cell lines

Special feature

In the GMP controlled facility, the maximum working culture volume is 200L for microbial cell lines with a stainless-steel bioreactor, and 500L for mammalian cell lines with a single-use bioreactor.


Reduction of cleaning validation

In the GMP controlled facility, all tanks except the microbial bioreactors are single-use types. Adoption of single-use tanks for media/ buffer preparation and mammalian cell culture reduces cross contamination risks, resulting in the reduction of cleaning validation burden.

Special feature

Details of the facilities

GMP controlled facility

Each operational room is in both microbial and mammalian cell areas arranged simply in the order of actual process, that is, starting with media/ buffer preparation room, culture room, purification room and a filling room (only the filling room is shared but not-simultaneously used).

In the microbial culture room, a bioreactor, disk type continuous centrifuge, and high pressure homogenizer (French press) are connected as a series to build a system that enables cleaning and sterilization of all connected apparatuses after use by the CIP and SIP program.
In the mammalian cell culture room, all bioreactors are single-use bag types. Culture in 0.1~25L volume range is run by a WAVE bioreactor, and cultures in 50L~100L volume range and 250~500L volume range are run by tank type bioreactors. The WAVE bioreactor is compatible with perfusion culture.

In either area, GE Healthcare’s AKTAplilot system is furnished for automated protein purification. The glass columns for chromatography with diameter of 10cm, 20cm, and 30cm are available. chromatography chambers and mobile chiller-jacketed buffer tanks are also available in the case of low temperature purification.

Filling drug substances is implemented in the bio-clean bench(class 100, inside) set up in the class 100,000 clean room. The filling process is mannually operated bulk filling.

Quality control room is in the uncontrolled air conditioning area where we use spectrophotometers, electrophoreisis apparatuses, HPLC, and UPLC for analyses.

Production technology laboratory (Non GMP controlled area)

Manufacturing Technology Research Laboratory is a P2 level lab, which consists microbial cell area, mammalian cell area, and an anteroom between them.

Have we do process development including small scale culturing and purification using a single-use small shaking bioreactor, parallel bioreactor systems, and medium pressure chromatograph systems.
