Interbasin water transfers are globally important water management strategies, yet little is known about their role in the hydrologic cycle at regional and continental scales. Specifically, there is a dearth of centralized information on transfer loc

Optimization of refolding conditions for progenipoietin was performed. The molecule has five disulfide bonds and, hence, is a challenge to refold. Variables studied included pH, DTT (dithiothreitol) concentration, cystine concentration, urea concentr

We have studied the effect of protein PEGylation on ion-exchange adsorption using bovine serum albumin as a model system. The free sulfhydryl group of BSA, located on cysteine 34, was PEGylated using the maleimido-PEG chemistry. Several different BSA
