Proteins iodinated by the chloramine-T method appear to be degraded at an abnormally rapid rate after endocytosis.


Proteins labeled with either (3)H by reductive methylation or (125)I by the chloramine-T method were incubated with Xenopus laevis oocytes; the incorporation and acid precipitability of the proteins were then studied. The uptake rates of both specifically incorporated (vitellogenin) and nonspecifically incorporated proteins (bovine serum albumin and X… (More)
