Effect of centrifugation on tryptic protein digestion

The effect of halogen salts on tryptic digestion.

THE effect of halogen salts on salivary and peptic digestion has been described previously [Clifford, 1925; 1927; 1928], and in this paper an account is given of their action on tryptic digestion. The earliest work on the subject appears to be that of Pfeiffer [1884] who found that, with the exception of sodium carbonate, all salts, especially sodium chloride, retard tryptic digestion. Later, W...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

The tryptic digestion of S-aminoethylated ribonuclease.

The peptides produced by the tryptic digestion of S-aminoethylated bovine pancreatic ribonuclease support the generally accepted amino acid sequence for this enzyme and also demonstrate the usefulness as well as some special limitations of the aminoethylation procedure. The relative extents of hydrolysis at different peptide bonds were estimated from the yields of purified peptides. Under the c...
