a-萘磷酸钠-坚牢兰B显现精斑指印研究

Detection of Semen Fingerprints by Solution Sodium α-Naphthyl Phosphate-Brentamine Fast Blue B

1987年英国法科学工作者B·H·Parkin采用琼脂制板法显现精斑指印，该法有一定的作用，但同时也受到许多条件的制约．如琼脂板的尺寸，限制了显现范围．不能完全满足现场劫查中搜寻、显现精斑指印的需要．

Acid phosphatase (AcP) in semen is very active and resistant to deneturation in old semen stains. When it reacts with solution Sodium α-Naphthyl Phosphate-Brentamine Fast Blue B, semen trace can be rapidly developed. Using this principle, we develop the latent semen fingerprints and find that this is an effective method.
