The technique of chemically assisted fragmentation was used to obtain de novo amino acid sequence data from tryptic peptides. |
In the first experiment, a fresh aliquot of intact actin was added to the tryptic digestion reaction of actin that has proceeded for 30 min. |
Those of Professor Hawk show a tryptic activity of from 18 to 20 per cent. |
This can be ascribed only to tryptic activity under the conditions of this experiment. |
The figures for tryptic activity given by Dr. Benedict do not differ materially from those of the first referee. |
In direct tests, however, practically no tryptic activity was demonstrated. |
