Frequently Asked Questions

Frequently Asked Questions are available for this Product.


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.

General description

γ-irradiated 50 mL polypropylene tubes fitted with a HDPE porous barrier and aseptically filled with 15 mL of Histopaque 1077. Each tube will separate 15-30 mL of anticoagulated blood.


Package contains 12 prefilled tubes

Frequently Asked Questions

Which document(s) contains shelf-life or expiration date information for a given product?

How do I get lot-specific information or a Certificate of Analysis?
A Certificate of Analysis is available by lot number and can be obtained through our Advanced Search Option: http://www.sigmaaldrich.com/catalog/AdvancedSearchPage.do
What are the most commonly used anticoagulants for the Accuspin tubes (Product A7054)?
EDTA or heparin are the most commonly used anticoagulants.  Heparin however should not be used when performing RNA assays.  EDTA can interfere with certain calcium binding assays.  Other anticoagulants have been reported to give acceptable results.
Does peripheral blood need to be diluted prior to loading into the Accuspin tubes (Product A7054)?
No.  The blood may either be used without dilution or with a 1:2 dilution.   In house studies at Sigma Aldrich have showed no decrease in recovery for peripheral blood specimens loaded directly into the Accuspin tubes.
May buffy coats or donor packs with reduced red cell numbers be used with Accuspin tubes (Product A7054)?
No.  For the mononuclear cells to band above the "frit", the specimen must contain a sufficient number of red cells to displace the density gradient above the "frit"
Can granulocytes be collected using the Accuspin tubes (Product A7054)?
No.  After centrifugation, the granulocytes will end up at the bottom of the Accuspin tube - just above the packed red blood cells.
