Plasma protein patterns in captive American kestrels

Abstract

1. 1. Plasma proteins of the American kestrel ( Falco sparverius) were analyzed by polyacrylamide disc electrophoresis for 3 different groups of birds: laying and non-laying females, and males. 2. 2. The electrophoretic patterns were homogeneous for each group and showed differences in the mobility of some proteins among the 3 groups. 3. 3. There was no significant difference among the 3 groups in the amount of proteins and in the standard parameter of albumin to globulin ratio.
