General description
ACCUSPIN System-Histopaque-1077 products are intended for use in the isolation of lymphocytes and other mononuclear cells. The separation medium, Histopaque-1077, is a sterile-filtered, endotoxin-tested solution of polysucrose and sodium diatrizoate, adjusted to a density of 1.077 g/mL. ACCUSPIN System-HISTOPAQUE-1077 employs centrifuge tubes specially designed with two chambers separated by a porous high-density polyethylene barrier ("frit").
γ-irradiated 12 mL polypropylene tubes fitted with a HDPE porous barrier and asepticallyfilled with 3 mL of Histopaque 1077. Each tube will separate 3-6 mL of anticoagulated blood.
Application
ACCUSPIN System-Histopaque-1077 is used for the separation of lymphocytes and other mononuclear cells from whole blood and bone marrow using density gradient separation media. Histopaque 1077 is suitable for:
- human lymphocyte antigen (HLA) typing and as the initial isolation step prior to enumeration of T, B, and ‘null’ lymphocytes.
- the preparation of pure lymphocyte suspensions for cell culture and cytotoxicity assays.
ACCUSPIN System-HISTOPAQUE-1077 employs centrifuge tubes specially designed with two chambers separated by a porous high-density polyethylene barrier ("frit"). The lower chamber contains HISTOPAQUE-1077 which allows the addition of anticoagulated whole blood without risk of mixing with the separation medium. On centrifugation, the whole blood descends through the frit to contact with the HISTOPAQUE-1077 below the frit, giving a clear separation of the blood components. The erythrocytes aggregate and the granulocytes become slightly hypertonic, increasing their sedimentation rate, resulting in pelleting at the bottom of the ACCUSPIN tube. Lymphocytes and other mononuclear cells, i.e., monocytes, remain at the plasma-HISTOPAQUE-1077 interface.
Features and Benefits
ACCUSPIN™ System-Histopaque®-1077 offers numerous advantages, such as:
- Optimal recovery of viable cells
- Permits selective separation of blood cell types
- Prevents cell distortion
- Preserves cell viability
- Minimal extraneous cell interference
- Reproducible performance from batch to batch
- Histopaque is sterile-filtered and endotoxin-tested
- Stable at 2-8°C for at least 2 years when protected from light
Principle
The lower chamber contains HISTOPAQUE-1077 which allows the addition of anticoagulated whole blood without risk of mixing with the separation medium. On centrifugation, the whole blood descends through the frit to contact with the HISTOPAQUE-1077 below the frit, giving a clear separation of the blood components. The erythrocytes aggregate and the granulocytes become slightly hypertonic, increasing their sedimentation rate, and resulting in pelleting at the bottom of the ACCUSPIN tube. Lymphocytes and other mononuclear cells, i.e., monocytes, remain at the plasma-HISTOPAQUE-1077 interface.
