Experimental design recovery

The scope of this chapter is devoted to solving Eq. (2) and the implications that thereby arise. Accordingly, a description of the physical system is presented (Section 4.2), experimental design is discussed at length (Section 4.3), data pre-processing is addressed (Section 4.4) the current status of pure component spectral recovery is reviewed along with the salient mathematical issues (Section 4.5), and future directions are indicated (Section 4.6). 

Thyroid hormone pretreatment has not been consistently resulted in cardioprotec-tion. Postischemic recovery of function has been reported to be reduced in hyperthyroid hearts subjected to no-flow global ischemia.79-81 However, this discrepancy is due to differences in the experimental design (reviewed by Pantos73). 

A lab-scale procedure for refolding the recombinant protein, secretory leukocyte protease inhibitor, was scaled to 1000 liter production batches. Optimization of reaction conditions by a statistical experimental design approach resulted in consistent activity recoveries of 80-85%, and lowered cost. The statistical design method allows simultaneous optimization of interacting process variables. Changes in the refold reaction conditions greatly influence the level of specific contaminants, thus purity becomes an important parameter in addition to yield. Our experience in the development, scale-up, and cost analysis of a protein refolding operation is presented.

Tom and coworkers obtained microparticulate protein powders of bovine insulin and catalase from solutions in ethanol/water mixtures by application of the SAS process (11). The experimental design required the proteins to be dissolved in ethanol/water 90 10 mixtures, which permitted only low concentrations of protein in the process flow. Particles of uniform size, but variable morphology, were obtained, but difficulties in product recovery were reported.
