Flashcards
Seminal Acid Phosphatase (SAP)
Seminal Acid Phosphatase (SAP)
An enzyme found in high concentrations in semen, with levels rising at puberty and peaking around age 40.
Brentamine Fast Blue
Brentamine Fast Blue
A color developer highly sensitive to semen, even when diluted up to 500x, used in forensic testing.
Semen Identification: Reaction Time
Semen Identification: Reaction Time
The reaction should occur rapidly (within 30 seconds) to be considered diagnostic for the presence of semen.
Study Notes
- Semen contains high levels of Seminal Acid Phosphatase (SAP).
- SAP levels rise at puberty until approximately age 40.
- Brentamine Fast Blue (a color developer) is highly sensitive to semen.
- It can detect semen even when diluted up to 500 times.
- Swabs should be obtained from orifices, skin, floors, condoms, walls, etc., to collect potential semen samples.
- A strong reaction within 30 seconds is diagnostic for semen.
