Product Overview

Acid Fuchsin Reagent is a colorimetric protein stain used in forensic investigations to enhance and visualize bloodstain patterns, particularly on porous surfaces such as textiles, paper, unsealed wood, and drywall. This reagent reacts with protein components—especially those found in blood—producing a deep magenta or reddish-purple coloration that increases the visibility of latent or diluted blood evidence.

In forensic applications, Acid Fuchsin is especially effective for enhancing faint or degraded bloodstains and can be used in both presumptive screening and blood pattern documentation. It offers excellent contrast on light backgrounds and helps define the edges and directionality of bloodstain patterns, supporting accurate interpretation and reconstruction at crime scenes.

While Acid Fuchsin is not specific to blood, its strong protein affinity makes it a valuable tool when paired with other confirmatory techniques. It is especially useful in cases where traditional luminol-based methods may be unsuitable or where non-fluorescent, visual enhancement is preferred.

Key Features:

• Stains proteins in blood to produce a deep magenta or red-purple coloration
• Enhances latent or faint bloodstains on porous surfaces
• Provides strong visual contrast for blood pattern documentation
• Ideal for crime scene reconstruction, especially with impact or drip patterns
• Works well on fabric, drywall, unsealed wood, and paper
• Non-fluorescent, making it useful where chemiluminescent methods may interfere

With Acid Fuchsin Reagent, forensic professionals gain a reliable and visually striking enhancement method for revealing subtle bloodstains—supporting both the detection and interpretation of critical scene evidence.
