Potential Applications in Research
Strictly in-vitro or analytical contexts. No health, diagnostic, or therapeutic claims.
- Redox & photochemistry — electron-transfer studies, photosensitization, and light-driven reactions with controlled illumination.
- UV-Vis method development — dye calibration, extinction-based quantitation, and instrument performance checks.
- Cell-free/microbiology staining — model staining and visualization protocols under controlled conditions.
- Assay QC/controls — colorimetric assay benchmarking and stability checks in buffered matrices.
- Chromatography/LC–MS sample prep — test analyte for method validation (carryover, recovery, light-stress studies).
Quality, Storage & Handling
Every lot is supported by a QR-linked COA. Independent U.S. labs verify identity and quantity, with endotoxin testing where applicable.
- Storage: 2–8 °C; protect from light; keep tightly closed. Do not autoclave the filled container.
- Handling: Use light-minimizing practices; avoid metal contamination; dye will permanently stain porous surfaces and some plastics.
- Shelf life: See lot COA and label. Use clean, dedicated tools to avoid introducing reductants/oxidants.
Shipping & Fulfillment
Ships in validated cold-chain packaging. In-stock orders placed before the daily cutoff ship the same day. 2-Day FedEx/UPS is standard, with overnight options available. Automated text/email updates included; international shipping available where permitted.
Compliance & RUO Disclaimer
For laboratory research only. Not a drug, cosmetic, food, or household chemical. Not for human or animal use, ingestion, diagnostic, or therapeutic applications. Buyers warrant they are qualified to handle RUO materials under applicable laws and institutional guidelines.
FAQs
- What is the concentration and volume?
- The bottle contains 500 mg of active dye in water. The exact concentration (mg/mL) and fill volume are printed on the label and listed on the COA (scan the on-vial QR).
- Is it sterile?
- Lots are 0.22 µm sterile-filtered and aseptically filled unless otherwise noted. Confirm sterility status on the COA for your lot.
- How should I store and handle it?
- Store at 2–8 °C, protected from light. Use amberware when possible, minimize light exposure during experiments, and avoid introducing strong oxidants/reductants unless required by your protocol.
- Can I use this in living systems?
- No. This product is sold strictly as RUO and is not for human or animal use.
