Subsequent attempts, however, on their part to isolate the compound were unsuccessful. As the quantity of our selenium-sulfur compound was small, and the supply of the source material was exhausted and could not be replenished for several weeks, it was decided that in the meantime it would be worth while to repeat the work of Kiister and Irion with the hope(More)
Food materials of vegetable origin constitute a large proportion of the diet of man and of animals. In many of the human foods, but more especially in the various animal feedingstuffs, lignin is present in some cases to the extent of 20 to 25 per cent of the dry weight of the food material. It is therefore rather surprizing that such a common food(More)
This paper is a continuation of a series of studies carried on in this laboratory some time ago on the digestibility of proteins in vitro (l-3). The data now presented are the results of some preliminary experiments carried out in connection with proposed studies on the rate of liberation of amino acids from different proteins on digestion. It is known that(More)
An important criterion used for the characterization of proteins is the amount of certain neutral salts that is required for the precipitation of proteins from their saline or aqueous solution. The amount of salt, such as ammonium sulfate, that is required to precipitate any given globulin is largely characteristic for the individual globulin. The(More)
The efficient expression and purification of an interfacially active peptide (mLac21) was achieved by using bioprocess-centered molecular design (BMD), wherein key bioprocess considerations are addressed during the initial molecular biology work. The 21 amino acid mLac21 peptide sequence is derived from the lac repressor protein and is shown to have high(More)
Surface plasmon resonance (SPR) measurements were used to screen refolding conditions to identify a physicochemical environment which gives an acceptable refolding yield for samples of glutathione-S-transferase (GST) denatured in 6 M guanidine hydrochloride and 32 mM dithiothreitol. The SPR measurements were performed on carboxymethylcellulose coated chips(More)
