Methylene Blue Solution, 3% Acetic Acid

CCM-DT-0006 is an acidified methylene blue staining solution supplied as a 100 mL liquid reagent. The formulation contains methylene blue with 3% acetic acid, combining a cationic biological dye with an acidic diluent that supports contrast development and sample clarification in common microscopy and cell-counting procedures. It is part of the CellCultureMedia detection reagent portfolio for R&D, process development, academic laboratories, and biomanufacturing support groups.

Methylene blue is widely used as a visual indicator stain because it binds strongly to negatively charged cellular components and provides blue contrast under brightfield microscopy. The 3% acetic acid component can help condition cell suspensions for manual examination and counting, particularly when users require rapid differentiation of cellular material against a lighter background. This product is not a complete culture medium and is not intended as a nutrient supplement; it is a prepared staining reagent for controlled analytical steps within cell-culture and bioprocess workflows.

• Manual cell counting workflows using hemocytometers or comparable counting chambers where visible blue contrast is required.
• Microscopy-based assessment of suspension or dissociated adherent cell samples during cell-culture process monitoring.
• Routine laboratory staining for training, protocol development, and comparative evaluation of sample preparation methods.
• In-process research checks where a simple colorimetric stain supports visual confirmation before downstream assays.
• Quality-control support in cell-culture operations when operators need a standardized 100 mL reagent format for repeatable handling.

Because staining response depends on cell type, sample density, exposure time, and dilution scheme, users should qualify the reagent in their own protocol before adopting it for routine release testing or regulated internal procedures. For coordinated supply with related buffers, media, sera, or reagents, procurement teams may use the request quote workflow to consolidate items and volume requirements.

Store CCM-DT-0006 at 2 to 30 °C in the original closed container. Keep the bottle tightly sealed when not in use to reduce evaporation and contamination risk, and protect the reagent from unnecessary exposure to intense light during storage and bench work. Allow the solution to equilibrate to the required working temperature before use if it has been stored in a cooler environment. Mix gently before dispensing; avoid vigorous shaking that may introduce bubbles into small-volume counting preparations. Use standard laboratory PPE and follow institutional chemical-handling procedures for acidified dye solutions. Do not use material that shows unexpected precipitation, leakage, container damage, or visible contamination.

CellCultureMedia supplies this reagent under ISO-aligned supplier-management and documentation practices appropriate for research and bioprocessing procurement. Lot-level documentation can be requested to support receiving inspection, internal traceability, and protocol records. Sterility, endotoxin, pH, osmolality, and shelf-life limits are not stated in the provided product specification; if these attributes are critical for your workflow, confirm available lot data before ordering through our quality documentation channel. Each order is packed for international laboratory supply, and free worldwide shipping is available where destination and carrier conditions permit.
