PurMa™ Dulbecco’s Modified Eagle’s Medium (DMEM)

Dulbecco’s Modified Eagle’s Medium (DMEM), High Glucose (4.5 g/L) – PurMa Biologics

Product Description for DMEM Media

Dulbecco’s Modified Eagle’s Medium DMEM high glucose 4.5 g/L is a high‑performance cell culture medium based on the classical Basal Medium Eagle (BME) formulation and optimized for robust, reproducible mammalian cell growth. it is one of the most widely used media in cell biology, molecular biology, and biotechnology applications due to its balanced composition of amino acids, vitamins, and salts. PurMa Biologics has been a major DMEM media supplier for more than 10 years.

High Glucose DMEM for Demanding Cell Lines

PurMa™ Dulbeccos Modified Eagles Medium DMEM is a modified version of Eagle’s Medium (DMEM) that has more glucose (4.5g/L) compared with the old version, which contained 1.0 g/L (1000 mg/L) glucose. PurMa Biologics DMEM culture media is formulated with:

• High glucose: 4.5 g/L – ideal for metabolically active and fast‑growing cell lines
• Optional low glucose variant (1.5 g/L, Cat. P3SO28105) – for cells requiring reduced glucose levels or more physiological conditions

This flexibility allows you to choose the optimal glucose concentration for your specific cell type and experimental design.

Enhanced Nutrient Profile

Compared to the original BME formulation, Dulbecco’s Modified Eagle’s Medium (DMEM) contains approximately fourfold higher concentrations of amino acids and vitamins, making it suitable for a broad range of cell culture applications. PurMa Biologics DMEM supports:

• Primary cultures of mouse and chicken cells
• A wide variety of normal and transformed mammalian cell lines

The enriched nutrient composition ensures reliable cell growth, viability, and productivity in both routine culture and more demanding experimental workflows.

Key Components of PurMa Biologics DMEM

Dulbecco’s Modified Eagle’s Medium DMEM high glucose 4.5 g/L  includes:

• High glucose (4.5 g/L)
• L‑glutamine (0.585 g/L) – supports protein synthesis and cell metabolism
• Non‑essential amino acids – reduce the biosynthetic burden on cells
• Phenol red (0.0015 g/L) – colorimetric pH indicator for easy visual monitoring
• Enhanced buffering capacity (3.7 g/L NaHCO₃) – provides stable pH in a CO₂ incubator

DMEM does not contain proteins, lipids, or growth factors, and therefore requires supplementation, typically with 10% Fetal Bovine Serum (FBS) or a suitable serum‑free supplement compatible with your cell type.

Superior Buffering and Culture Stability

The increased sodium bicarbonate content (3.7 g/L NaHCO₃) gives Dulbecco’s Modified Eagle’s Medium (DMEM) significantly improved buffering capacity compared with earlier formulations. This helps maintain:

• Stable pH during extended culture
• Consistent cell morphology and performance
• Reproducible experimental outcomes across batches

Types of DMEM by PurMa Biologics

PurMa Biologics manufactures three optimized forms of Dulbecco’s Modified Eagle’s Medium (DMEM):

1. DMEM Standard – reliable, general‑purpose formulation for routine cell culture
2. DMEM MAX – enhanced formulation for high‑density cultures and demanding cell lines
3. DMEM Advanced – optimized for modern applications such as serum reduction, scaled‑up production, and advanced research workflows

Each DMEM type results from decades of cell culture research and optimization, delivering exceptional cell growth, viability, and lot‑to‑lot consistency for your projects.
