Abstract: | Rabbit alpha-1-M and alpha-2-M labelling was carried out in vitro with 131I and in vivo with 75-Seleno-methionine in order to determine the half-life of these proteins. alpha-2-M catabolism is faster than the alpha-1-M one. This result is the same when these proteins were obtained from a plasma of a rabbit exhibiting an inflammatory reaction though their half life was shorter. |
