Isolate mononuclear cells from peripheral blood, cord blood, or bone marrow with Lymphoprep™—a cost-effective alternative to Ficoll-Paque™.

Product name Nycodenz AG®
It’s a gradient medium derivate of benzoic acid with three aliphatic hydrophilic side chains.

Simplify the isolation and purification of macromolecules; viruses; a wide range of cell types; and organelles such as nuclei, mitochondria, endosomes, or exosomes by using OptiPrep™ medium. This flexible, versatile, and gentle density gradient medium is non-ionic, iodixanol-based (60% w/v) and has a density of 1.320 ± 0.001 g/mL. OptiPrep™ has been used clinically in X-ray contrast imaging and has been shown to have lower toxicity when compared to ionic gradient compounds such as metrizamide.

Storage and Stability Conditions of Polymorphprep™

• Polymorphprep™ should be stored at room temperature (20°C).
• It’s stable for 3 years provided the solution is kept sterile and protected from light.
• Prolonged exposure to direct sunlight leads to release of iodine from the Sodium Diatrizoate molecule (this effect is negligible when working with the solution on a day to day basis.)
Brand Axis-shield

Polymorphprep is a type of density gradient medium that is used in laboratory settings to separate cells or other biological particles based on their size and density. It is commonly used in a technique called density gradient centrifugation, which involves spinning a tube of Polymorphprep and other components at high speeds to create a gradient of increasing density. This gradient allows cells or other particles to be separated based on their density and size, with heavier or denser particles settling towards the bottom of the tube and lighter or less dense particles remaining towards the top.

Polymorphprep is a specific brand of density gradient medium that is made by Sigma-Aldrich, a company that specializes in supplying chemical, biological, and pharmaceutical products to researchers and other professionals. It is commonly used in a variety of applications, including blood transfusion, tissue culture, and gene expression analysis. Polymorphprep is also used in research and diagnostic laboratories to purify or isolate cells or other biological materials, such as viruses or proteins.

Applications Isolation of human polymorphonuclear cells
Composition The solution contains Sodium Diatrizoate and Dextran 500 in the following concentrations:

• Sodium diatrizoate 13.8% (w/v)
• Dextran 500 8.0 (w/v)
Principle of the separation procedure
How Polymorphprep™ works

Polymorphonuclear leukocytes (PMNs) has a lower buoyant density than erythrocytes (1.09-1.11 g/ml) but a higher buoyant density than the mononuclear cells (higher than 1.085 g/ml). Therefore, it is difficult to isolate polymorphonuclear granulocytes using a density barrier similar to that used for mononuclear cell. Several procedures have been developed to overcomes these issues.
The high osmolality of Polymorphprep™ causes erythrocytes to lose water and shrink, thus increasing their effective buoyant densities. This allows the dextran aggregated erythrocytes to sediment rapidly through the dense medium.
As the cells sediment further into the medium, the osmotic gradient between the medium and the erythrocytes declines. This means that water loss from the erythrocytes is greater at the top of the Polymorphprep™ and progressively decreases as they sediment further. A gradient of diatrizoate is formed within the density barrier. The PMNs band within this density gradient while the mononuclear cells remain at the sample/medium interface.
Advantages
Polymorphprep™ vs Ficoll-Paque

• Ficoll-Paque (GE Health Care) is not endotoxin tested at a base level and higher price
• Unlike Polymorphprep, Ficoll-Paque is not manufactured under EU cGMP compliance.
Alternatives Polymorphprep™ can be a good substitute for Ficoll-Paque

Dr. Arne Bøyum reported in 1968 a simple and efficient method for the isolation of mononuclear cells from human blood. For more than 45 years, a commercial medium known as Lymphoprep has been widely used to isolate these cells.

PPM is a type of Plant Preservative Mixture
sold by Maxanim in volunes of 100ml with the product code PPM.0100

Plant Preservation Mixture (PPMTM) is a robust broad-spectrum biocide formulated for use in plant tissue culture. PPMTM targets bacteria and fungi in plant tissue culture growth media as well as contaminated tissue. It affects key enzymes in the Krebs cycle and in the Electron Transport Chain. Depending on the dose and the level of contamination, PPM is a biocidal component in plant culture medium. In addition, it may also function as a biostatic compound as a preventative measure. When diluted with plant growth media it is effective as a microbiocide (i.e. bactericide and fungicide) against non-human health pathogenic organisms component of liquid or semi-solid plant culture media.

Plant Preservative Mixture, also known as PPM, is a solution that is used to preserve plant tissues for scientific research or other purposes. It is typically made up of several chemicals that help to prevent the tissues from deteriorating or becoming contaminated during storage or transportation.

There are many different formulations of PPM, and the specific composition of the mixture can vary depending on the specific needs of the research or application. Common ingredients in PPM formulations include chemicals that help to inhibit the growth of microbes (such as antibiotics or antimicrobial agents), protect against oxidative damage (such as antioxidants), and maintain the structural integrity of the plant tissues (such as tissue fixation agents).

PPM is commonly used in research and diagnostic laboratories to preserve plant tissues for analysis or other purposes. It is also used in a variety of other applications, including horticulture and agriculture. It is important to follow the manufacturer's instructions and safety precautions when handling PPM, as some of the chemicals it contains may be toxic or hazardous.

PPMTM is effective for most seed baring plants - angiosperm, as well as gymnosperm,- however, it is not recommended for use in ferns, mosses, algae and aquatic plants. Optimization may be required to maximize potency. While PPM is an excellent tool in the prevention and elimination of culture contamination it is not a substitute for asceptic laboratory techniques and appropriate air handling systems are recommended.
