Human Whole Blood
Gain unparalleled access to freshly collected human
whole blood—even from populations and for study
designs that seem impossible to achieve.
Whole Blood Samples
Our whole blood samples are suitable for numerous downstream applications and can be further processed if you need to isolate specific cell types. Using standardized sample collection and storage protocols, we can deliver same-day or next day including disease-associated event-based samples while ensuring high quality and cell viability.
With every human whole blood sample, you’ll receive detailed patient data that’s validated through medical record review, so you can confidently develop your next therapeutic or diagnostic solution.
FAQ
Once removed from the body, the handling of whole blood is crucial to ensuring it’s preservation and overall function. As a standard rule, whole blood should be stored at a temperature between +2 ℃ to +6 ℃. Data has shown that this temperature will dramatically slow degradation and ensure viability for future use for about a month. Below +2 ℃, whole blood will become hemolyzed, which means that red blood cells will begin to rupture. Above +6 ℃, the risk of bacterial contamination will dramatically increase.
Fresh whole blood becomes important when working with specific isolates, such as platelets. Platelets will begin to denature as soon as they are removed from a biological environment, with maximum stability for about 8 hours at ambient conditions, and notable degradation beginning at the 2-hour mark.
Sanguine’s same-day delivery is critical for getting sensitive isolates such as platelets to its customers—stably and ready for use. We even have the ability to collect and deliver a sample within a 4-hour period.

Compliance & Quality Assured
Sanguine utilizes two internationally-recognized IRBs (Advarra and WCG IRB) for review and approval of all study protocols, specific study documentation, and study participant facing information. Both Advarra and WCG IRB are organized and operates in compliance with: FDA, OHRP, International Conference on Harmonization (ICH) and Association for the Accreditation of Human Research Protection Programs (AAHRPP).
Sanguine operates under an electronic informed consent process which executes 21 CFR part 11 compliant e-signatures, and Sanguine systems interacting with study participant information are HIPAA-compliant.
