Overview
CCM-RG-0005 is a phenol red-free Dulbeccoโs phosphate buffered saline formulation containing calcium and magnesium ions. It is designed as a balanced salt solution for routine cell culture operations where a defined inorganic salt environment is required without serum, proteins, dyes, or animal-derived components. The presence of Ca2+ and Mg2+ supports procedures where divalent cations are required for cell attachment characteristics, cell-to-cell interactions, or compatibility with downstream reagents. The absence of phenol red reduces color interference in workflows that use optical, fluorescence, or absorbance-based readouts.
This product is supplied as a sterile-filtered liquid in a 500 mL format and is classified as animal origin-free. Key release specifications include pH 7.0โ7.4 and osmolality of 270โ300 mOsmol/kg, aligning it with common isotonic handling requirements for mammalian cell culture. The reagent is positioned in the balanced salt solution segment of our cell culture reagents portfolio and is suitable for procurement programs that require consistent documentation, lot traceability, and predictable supply. For standing orders, multi-site purchasing, or volume planning, buyers can request a quote referencing CCM-RG-0005.
Applications
- Rinsing adherent cell monolayers before dissociation, staining, media exchange, or reagent addition when calcium and magnesium should remain present.
- Short-term cell handling, washing, or dilution steps in research cell culture workflows that require an isotonic phosphate buffered saline system.
- Preparation of cell suspensions, reagent dilutions, and assay wash buffers where phenol red-free composition is preferred to reduce background signal.
- Use in upstream process development, academic core laboratories, quality-control development, and non-GMP bioprocess support environments requiring sterile-filtered liquid reagents.
- Compatibility screening for cell lines and primary cell-derived research models where animal origin-free raw materials are part of sourcing requirements.
Storage and Handling
Store CCM-RG-0005 at 2โ30 ยฐC protected from light. The product ships at room temperature, supporting simplified receiving and inventory workflows without cold-chain handling for standard transit. Do not freeze unless internally validated, as freezing may affect container integrity or salt distribution after thawing. Before use, inspect the bottle for seal integrity, clarity, particulates, and expiration status. Handle aseptically after opening and minimize repeated exposure to non-sterile environments. The stated shelf life is 48 months when the product is stored unopened under recommended conditions. Once opened, laboratories should apply their own in-use dating policy based on aseptic technique, frequency of access, and internal quality requirements.
Quality and Documentation
CellCultureMedia supplies CCM-RG-0005 under ISO-aligned quality practices appropriate for research and bioprocess reagent distribution. Lot-specific documentation can be provided on request, including a Certificate of Analysis when available, to support incoming inspection, batch record attachment, and supplier qualification files. Release attributes include sterile-filtered status, animal origin-free classification, pH range, osmolality range, fill size, storage conditions, shipping conditions, and shelf life. For procurement teams standardizing balanced salt solutions across sites, this specification set supports easier comparison, approval, and reorder control.
Free worldwide shipping is available through CellCultureMedia ordering channels, with final logistics confirmed by destination, quantity, and export requirements. For supplier onboarding, quality questionnaires, or documentation review, visit our quality resources or contact the sales team with the CCM SKU, required quantity, and delivery location. Bulk pricing, scheduled releases, and consolidated shipments can be arranged for laboratories and manufacturing support groups that require recurring supply.

Learn more about this
- HBSS (Hank's Balanced Salt Solution)HBSS (Hank's Balanced Salt Solution) is an isotonic balanced salt solution used to wash cells, transport tissue, dilute reagents and hold cells briefly outside their growth medium. It contains 8.0 g/L sodium chloride, 1.0 g/L D-glucose, phosphate and 350 mg/L sodium bicarbonate, and is supplied either with calcium and magnesium (1.26 mM Ca, ~0.9 mM Mg total) or without them. Its low bicarbonate means it is designed for use at atmospheric CO2 or in sealed vessels, not for prolonged culture in a 5% CO2 incubator.
- PBS vs DPBS: What Is Different, and Which One to UsePBS and DPBS are both phosphate-buffered saline solutions; the difference is the recipe, not the function. Dulbecco's formulation (DPBS) adds potassium chloride and carries roughly twice the phosphate of a typical PBS (about 9.5 mM versus about 4 mM), and it is sold in two versions - with calcium and magnesium, and without. In practice the with-or-without-divalent-cations choice matters far more than the PBS-or-DPBS label: use a calcium- and magnesium-free solution to wash cells before trypsinisation or EDTA dissociation, because Ca2+ and Mg2+ support the cadherin and integrin bonds you are about to break, and use the version containing calcium and magnesium when cells must stay attached and intact through the wash.
- Cell culture buffersCell culture buffers hold medium in the pH 7.2-7.4 range that mammalian cells require, against the acid load cells generate as they metabolise. The default system in almost every classical medium is sodium bicarbonate working with the CO2 in the incubator atmosphere, which is why bicarbonate content must be matched to the incubator setting: about 1.5-2.2 g/L NaHCO3 for 5% CO2 and 3.7 g/L for 10% CO2. Organic buffers such as HEPES (pKa 7.48) are added at 10-25 mM to hold pH when cultures are outside a CO2 atmosphere, while phosphate-buffered solutions such as PBS and DPBS are used for washing and short-term handling rather than for growth.
