How do you dissolve Ficoll 400?

To prepare a 20% (w/v) of Ficoll 400, dissolve the Ficoll in sterile H2O and store the solution frozen in 100-μl aliquots at -20°C.

How do you cook Ficoll?

Preparing a discontinuous gradient: Prepare Ficoll 400 in buffer or isotonic sucrose solution (0.25M) at concentrations that should separate the material of interest. Most cells and organelles have a buoyant density between 1.0 and 1.2 g/ml in Ficoll 400. Often a two-layer gradient is sufficient.

How do you store Ficoll?

Ficoll-Paque PLUS should be stored between 4 °C and 25 °C and protected from direct light. Storage of unopened bottles in the dark will increase their shelf-life. Deterioration of Ficoll-Paque PLUS is indicated by the appearance of a distinct yellow colour or particulate material in the clear solution.

What is ficoll400?

Ficoll 400 is a highly branched polymer formed by the copolymerization of sucrose and epichlorohydrin. Ficoll 400 is completely non-ionic. The most common application for Ficoll 400 is as a density gradient medium for the separation and isolation of eukaryotic cells, organelles and bacterial cells.

Can you filter Ficoll?

Dissolve Ficoll and NaCl in 600 ml water using a magnetic stirrer at low speed. When all components are in solution, add water to 1 liter. Filter sterilize with a 0.22-μm filter unit. Store at 4° to 25° C and protect from direct light.

Is 47% lymphocytes normal?

The normal range for lymphocytes is between 800 and 5000 (0.8-5.0) lymphocytes per mL of blood. A normal lymphocytes percentage is 18-45% of total white blood cells.

What is Ficoll 400 used for?

The most common application for Ficoll 400 is as a density gradient medium for the separation and isolation of eukaryotic cells, organelles and bacterial cells. Density ranges up to 1.2 g/ml can be attained. It has also been utilized in a variety of other applications.

What is the density of Ficoll 400?

Because of the abundance of hydroxyl groups, Ficoll 400 is very hydrophilic and extremely water-soluble. The most common application for Ficoll 400 is as a density gradient medium for the separation and isolation of eukaryotic cells, organelles and bacterial cells. Density ranges up to 1.2 g/ml can be attained.

What is Ficoll-Hypaque made of?

Applications calling for Ficoll-Hypaque employ a mixture of Ficoll and sodium diatrizoate. We offer preformed mixtures of three different densities under the product names Histopaque-1077, 1083, and 1119. Ficoll 400 is a constituent of Denhardt’s solution used in Northern and Southern blot analysis.

What is the solubility of Ficoll in water?

Concentrations of 50% (w/v) can be attained in water. Ficoll should be added slowly with constant stirring. Sigma tests the solubility of Ficoll 400 at 1 g in 10 ml of deionized water yielding a clear to slightly hazy, colorless to faint yellow solution. Ficoll is stable in alkaline and neutral solutions.
