After dialysis the sample was centrifuged and the supernatant placed on a * * f cm column of DEAE-cellulose equilibrated with starting_buffer .
For preparative ultracentrifugation , fractions from the column were concentrated by negative pressure dialysis to volumes of 1 ml or less , transferred to cellulose tubes and diluted to 12 ml with isotonic saline .

The last column shows the rate of exchange that would have been observed at a relative intensity of 4 ( 14.7 cm. distance ) calculated on the assumptions that the incident light intensity is inversely proportional to the square of the distance of the lamp from the cell and that the rate is directly proportional to the incident light intensity .
Direct proportionality of the rate to the incident intensity has also been assumed in obtaining the value in the last column for the fourth sample of series /2 , where the light intensity was reduced by use of a screen .
