iLG
Bloodstain Enhancer
iLG Bloodstain Enhancer is a water-based staining solution for traces in blood. It has a number of advantages compared to other staining solutions. It is safe (water-based), stains well, and can be lifted with a white gelatin lifter. A special characteristic of iLG Bloodstain Enhancer is that the lifted traces fluoresce under green light, making it possible to visualize weak traces, even when they are present on a dark surface.

Features
· Using water as solvent, the formula is harmless, non-irritating odor, safe and environmentally friendly
· It has high visibility in natural light and at the same time has strong fluorescence
· Suitable for a wide range of impermeable object surfaces from light to dark
· The fluorescence is a distinctive red color, which effectively avoids interference from other visible fluorescence produced by the background
· The formula system is stable and valid for more than 18 months at room temperature
· After staining, it can be easily extracted and transferred through film
· Does not destroy DNA.
How to use (Please do a controlled test first)
1. Treat the potential blood stains with fixative first, and wet themthoroughly for more than 1 minute;
2. Then wet the potential blood stain with dye reagent for more than 1minute to fully color the blood stain;
3. Wash the stained blood stains with detergent until the dye on theobject background is fully rinsed;
4. Dry by cold air, or gently absorb the residual solvent throughabsorbent paper;
5. Then observe the effect of dyeing in a sufficient light environment,further check the fluorescence effect through green light, and use a filter tocompletely filter out the excitation light when viewing fluorescence;
