Used primarily as a protein stain, this high-purity dye binds selectively to blood-contaminated friction ridges on porous and non-porous surfaces. The compound produces a dark blue coloration that significantly increases visual contrast. Forensic professionals rely on this specific formulation to extract critical ridge detail from complex or faintly stained crime scene evidence.\u003c\/p\u003e\n\u003cp\u003eEngineered for laboratory customization, the dry powder format allows technicians to formulate specific working solutions based on casework requirements. By dissolving the dye into appropriate carrier solvents like methanol and acetic acid, examiners can control the exact concentration of the stain. When integrated into standard operating procedures, this flexibility ensures court-admissible visual enhancements. The fine particulate structure dissolves efficiently into standard forensic solvent mixtures, minimizing preparation time.\u003c\/p\u003e\n\u003cp\u003eTo prevent sample degradation, the targeted evidence should ideally be pre-treated with a chemical fixative before applying the prepared dye solution. Maintaining strict control over the application and rinse processes keeps the active chromophores firmly attached to the targeted blood print. For optimal laboratory safety, preparation and mixing should always occur within a certified fume hood. Technicians must utilize appropriate personal protective equipment to prevent inhalation of the fine dust.\u003c\/p\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\"\u003ePF15019-25g\u003c\/td\u003e\n  \u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003e25 g\u003c\/td\u003e\n  \u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePowder\/Bottle\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\"\u003eProtein Stain Powder\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\"\u003eMust be dissolved in solvent prior 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 rigorous forensic environments, integrating this protein dye is critical when processing evidence recovered from violent incident scenes. Crime scene investigators rely on this step when examining complex items like clothing, footwear, or textured flooring. Because it selectively adheres to the protein matrix of blood deposits, the solution is highly valuable when natural contrast is insufficient. Extracting usable intelligence requires a chemical dye that binds aggressively to biological material.\u003c\/p\u003e\n\u003cp\u003eWhen processing blood evidence, the prepared working solution is typically applied via submersion or a controlled wash over the fixed print. Technicians gently rinse the item with a clearing solvent (like a methanol rinse) to remove excess background staining before air drying. Upon achieving the desired ridge contrast, the evidence is photographed under standard lighting conditions. This critical documentation step ensures the capture of the highest possible resolution of the print.\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 G250\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\"\u003eQuality Control\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eHigh purity \/ COA available\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eUnverified purity\u003c\/td\u003e\n\u003c\/tr\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\"\u003eDry powder for custom mixing\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePre-mixed only\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.
