Bovine Whole Blood, Heparin, Non-Sterile

Whole blood and plasma come with sodium citrate, EDTA, heparin, ACD, CPD or Alsever's solution, and a few with potassium oxalate or sodium fluoride. Citrate, ACD, CPD and EDTA bind calcium (citrate reversibly, so it is the usual pick for coagulation work); heparin acts through antithrombin and leaves calcium available; Alsever's is a citrate preservative that extends red cell life; fluoride and oxalate hold glucose stable for clinical chemistry. Use whichever your assay tolerates. EDTA, for example, interferes with calcium- and magnesium-dependent reactions.

Typical anticoagulant ratios are 9 parts blood to 1 part anticoagulant. Specific ratios are provided in the Product Datasheets and Certificates of Analysis for each product where applicable.

For applications demanding fresh whole blood, we recommend usage within 5-7 days or as soon as possible after delivery. These products may be suitable for a longer period in other applications with less stringent requirements, though we suggest usage within 30 days of delivery.

Generally, we do not recommend freezing whole bloods as the freeze-thaw process will result in red blood cell lysis. However, certain applications may call for freezing or other treatment of whole bloods or any of our other products. Our products are meant to serve as raw materials or intermediates and therefore may be used in a wide variety of end use applications.

Our typical animal blood product lot sizes range from 50 L to 200 L.

Yes, depending on the species and collection environment, aseptic collection techniques are practiced whenever possible. In animal collection facilities where aseptic technique may not be feasible, materials are collected as carefully as possible by highly trained technicians. Animal blood products are collected in an abattoir environment.
