Used heavily in violent crime scene processing, this pre-mixed protein stain binds selectively to biological material on both porous and non-porous surfaces. The resulting dark blue coloration maximizes visual contrast for forensic documentation. Investigators rely on this solution to recover intelligence from faintly stained or visually noisy evidence.\u003c\/p\u003e\n\u003cp\u003eEngineered for high-throughput forensic environments, this ready-to-use formulation eliminates the need for complex manual powder mixing. By providing a standardized working strength, technicians ensure court-admissible enhancements with consistent batch-to-batch reliability. When incorporated into standard workflows, the specific carrier solvents promote deep penetration into the protein matrix. This creates a long-lasting, brilliant stain that resists fading during the photographic phase.\u003c\/p\u003e\n\u003cp\u003eTo prevent sample degradation, the evidence must be properly stabilized with a chemical blood fixative before applying this aqueous stain. Maintaining strict control over the application sequence keeps the delicate print structures securely attached to the substrate. For optimal laboratory safety, this chemical should always be applied within a certified fume hood. Technicians must utilize appropriate personal protective equipment to minimize exposure to the solvents.\u003c\/p\u003e\n\n\u003cdiv style=\"background-color: #f8f9fa; border-left: 4px solid #0056b3; padding: 15px; margin: 1.5em 0;\"\u003e\n  \u003cp style=\"margin: 0;\"\u003e\u003cstrong\u003eRequired Processing Step:\u003c\/strong\u003e For optimal background clearing and print visibility, use this primary protein stain in conjunction with the dedicated \u003ca href=\"\/products\/coomassie-blue-rinse\" style=\"color: #0056b3; text-decoration: underline; font-weight: 600;\"\u003eCoomassie Blue Rinse\u003c\/a\u003e.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eAvailable Sizes and Configurations\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #ddd;margin:1em 0\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n  \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eSKU\u003c\/th\u003e\n  \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eVolume\u003c\/th\u003e\n  \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eFormat\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n  \u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePF30092-500mL\u003c\/td\u003e\n  \u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003e500 mL\u003c\/td\u003e\n  \u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eBottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #ddd;margin:1em 0\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n  \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eSpecification\u003c\/th\u003e\n  \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eProduct Type\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePre-Mixed Protein Stain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eTarget Material\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eBlood-contaminated latent prints\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eDeveloped Color\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eDark Blue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eApplication Phase\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePrimary enhancement (post-fixation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePreparation Requirement\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eReady to use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eLaboratory Applications\u003c\/h2\u003e\n\u003cp\u003eFor specialized forensic operations, integrating this pre-mixed dye is critical after the initial blood fixation process. Crime scene investigators rely on this step when processing challenging items like clothing, linoleum, or painted surfaces. Because it selectively adheres to the biological proteins, the formula is highly valuable when natural contrast is insufficient. Extracting usable intelligence requires a chemical wash that binds aggressively to the target evidence.\u003c\/p\u003e\n\u003cp\u003eWhen processing blood evidence, the working solution is typically applied via complete submersion or a controlled flow method. Technicians gently wash the item with a dedicated destaining clearing solvent to remove excess background staining before air drying. Upon achieving the desired ridge contrast, the evidence is immediately photographed under standard lighting conditions. This critical documentation step ensures the capture of the highest possible resolution.\u003c\/p\u003e\n\n\u003ch2\u003eForensic Reagent Comparison: Why Choose Rocky Mountain Reagents?\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #ddd;margin:1em 0\"\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eFeature\u003c\/th\u003e\n      \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eRocky Mountain Reagents Coomassie Blue Reagent\u003c\/th\u003e\n      \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eTypical Competitor\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eFormat\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePre-mixed liquid\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eRequires manual powder mixing\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eConsistency\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eStandardized working strength\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eVariable batch quality\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePricing\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eBelow retail pricing\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eFull retail\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eShips From\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eUSA inventory\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eVaries\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eAcademic and Institutional Pricing\u003c\/h2\u003e\n\u003cp\u003eLabSupplies.com offers tiered quantity pricing for academic and research institutions.
