| 摘要 |
The present invention relates to a plasmin solution comprising: (A) plasmin and (B) the following component (B-1), (B-2) or (B-3): (B-1) an oligopeptide comprising at least two amino acids bonded each other, said two amino acids being selected from lysine, arginine, glycine, alanine, aspartic acid and methionine; (B-2) at least two amino acids selected from lysine, arginine, glycine, alanine, aspartic acid and methionine; or (B-3) an amino acid selected from lysine, arginine, glycine, alanine, aspartic acid and methionine and a polyhydric alcohol. This solution is maintained stably without deteriorations in the plasmin activity and binding activity with alpha 2PI even after long-term storage so that it is useful as a reagent for the quantitative measurement of alpha 2PI. n |
