#SCPH05 I Biotechnology
  1. Homology modeling requires a  model to be built 
  2. Homology modeling requires alignment of a target to a template 
  3. Homology modeling is usefully applied to any protein sequence 
  4. The accuracy of homology modeling is independent of the percent identity between the target and the template

Hybridoma cells immobilized on surfaces of Sephadex beads are used in a packed column for production of monoclonoal antibodies (Mab). Hybridoma concentration is approximately X = 5 g/l in the bed. The flow rate of the synthetic medium and glucose concentration are Q = 2 l/h and S0 = 40 g/l, respectively. The rate constant for Mab formation is k = 1 gX/l-d. Assume that there are no diffusion limitations and glucose is the rate limiting nutrient.  Determine the volume of the packed bed for 95% glucose conversion. Bed diameter is D0 = 0.2 m. Neglect the growth of the hybridomas and assume first order kinetics.
