Allgemeine Beschreibung
Histopaque®-1119 ist ein steriles, endotoxingeprüftes, gebrauchsfertiges Medium. Die Lösung besteht aus Polysaccharose und Natriumdiatrizoat, eingestellt auf eine Dichte von 1,119 g/ml und einen pH-Wert von 8,8 bis 9,0.
Anwendung
Histopaque®-1119 eignet sich zur Verwendung in Kombination mit Histopaque-1077, da es die schnelle Rückgewinnung von lebensfähigen mononukleären Zellen und Granulozyten aus kleinen Mengen Vollblut oder Knochenmark ermöglicht.
Leistungsmerkmale und Vorteile
Histopaque®-1119 bietet zahlreiche Vorteile, z. B.:
- optimale Rückgewinnung von lebensfähigen Zellen
- selektive Trennung der Blutzelltypen
- keine Zellverformungen
- Lebensfähigkeit der Zellen bleibt erhalten
- minimale Interferenz durch Fremdzellen
- reproduzierbare Leistung von Charge zu Charge
- sterilfiltriert und endotoxingeprüft
- vor Licht geschützt bei 2–8 °C mindestens 2 Jahre stabil
Prinzip
Der Prozess umfasst das Bilden eines Doppelgradienten beim Schichten eines gleichen Volumens Histopaque-1077 über Histopaque-1119. Antikoaguliertes Vollblut wird vorsichtig auf das obere Histopaque-1077-Medium geschichtet. Beim Zentrifugieren werden Erythrozyten durch Polysaccharose aggregiert und setzen sich dadurch schnell ab. Granulozyten kommen an der unteren Histopaque-1077/1119-Grenzfläche vor, wogegen Lymphozyten und andere mononukleäre Zellen an der oberen Plasma/Histopaque-1077-Grenzfläche vorkommen. Die meisten unerheblichen Thrombozyten, die in der oberen Grenzfläche vorkommen, werden durch Zentrifugieren bei langsamer Geschwindigkeit während Waschschritten entfernt. Die Erythrozyten-Kontaminierung ist vernachlässigbar.

Ficoll 400® is a non-ionic polymer with high hydrophilicity and water solubility, suitable for various biological applications.
Ficoll®-400 ist ein hochverzweigtes Polymer, das durch Copolymerisation von Saccharose und Epichlorhydrin gebildet wird. Ficoll® 400 ist vollständig nicht-ionisch. Aufgrund der großen Anzahl an Hydroxylgruppen ist Ficoll® 400 sehr hydrophil und extrem wasserlöslich.

Is the Histopaque-1119 solution compatible with blood stored in PAXgene cell-free DNA tubes for separating different cells from the blood when used in combination with Histopaque-1077 for a double gradient?
1 answer-
The PAX gene Blood DNA tubes were not tested for compatibility with any of the Histopaque products. As a general rule, fresh blood provides the best results with the Histopaque products, and it is generally not recommended to use blood stored for more than 24 hours.

Is it possible to use Histopaque 1119 as a double gradient media with another brand of density gradient media, such as Ficoll paque plus, or does it only work with Histopaque 1077?
1 answer-
Histopaque and Ficoll Paque are chemically identical solutions. For all practical purposes, both have polysucrose 400.

Are there any comparable products for Pancoll at densities 1.119 g/ml and 1.077 g/ml, to be used in cell isolation for gene expression studies or diagnostics.
1 answer-
As Pancoll is polysucrose-based, Histopaque and Ficoll Paque have essentially the same formulations. For Histopaque and Ficoll Paque, products are available with densities of 1.073, 1.077, 1.083, 1.084, and 1.119 g/ml. Any of the Histopaque and Ficoll Paque products with densities of 1.077 g/ml and 1.119 g/ml should be suitable crossmatches for Pancoll products with densities of 1.077 g/ml and 1.119 g/ml.

Hi. I am trying to adapt an older protocol that calls for a certain percentage of Ficoll. What percentage does this product contain?
1 answer-
This product is a mixture of Ficoll (polysucrose 400) and sodium diatrizoate at 60 grams and 167 grams per liter, respectively. The solution may not be a suitable substitute for protocols requiring Ficoll, only. Please see product F5415 to review a 20% Ficoll solution in water. This item may a better option:

The Product 11191, Histopaque®-1119, froze in transit. Is the product still suitable for use?
1 answer-
Mix the bottles upon receipt several times to ensure the product is uniform. The products are shipped ambient and gradients in situ can form if the solution freezes during transport. As long as the bottle has not broken and no precipitate is noted, the product is suitable for use after slowly thawing and mixing.

Can the procedure for using Product 11191, Histopaque®-1119, be used successfully with species such as rats and mice?
1 answer-
The Histopaque 1119-1 procedure was developed for use with human blood. Due to the lower number of circulating neutrophils in rat or mouse peripheral blood, the technique tends not to work as well with rats or mice.
