This stable form of PAI-1 contains an N-terminal cysteine mutation in addition to the four stabilization point mutations. A substitution of Glutamic Acid for Arginine at position 76 greatly decreases the binding of this Human PAI-1 mutant to the low density lipoprotein receptor-related protein (LRP). The protein is supplied in buffer with 1mM DTT to prevent dimerization. To label with thiol reactive dye, buffer exchange into degassed 0.05M Sodium Phosphate; 0.1M NaCl; 1mM EDTA; pH 6.6 by desalting column. Collect into 10 fold molar excess of maleimide or iodoacetamide dye and incubate for 1 hour at room temperature. To preserve PAI-1 activity minimize the percentage of DMSO/DMF in the reaction. Remove free dye by desalting, ammonium sulfate precipitation, or dialysis.
