Time-dependence of [14C]heme-binding to α1m.
Approximately 0.2 nmol plasma-α1m, t-α1m, human serum albumin (HSA), and orosomucoid was incubated with 25 pmol [14C]heme for 1, 3, 15, 60, and 180 minutes. The binding of [14C]heme to the proteins was then determined by SDS-PAGE, staining (A), and phosphoimaging (B).
