What are PBMCs?
PBMCs, or peripheral blood mononuclear cells, are a type of blood cell that plays a crucial role in the immune system.
Why is cryopreservation important?
Cryopreservation allows for the long-term storage of cells, enabling time-independent analysis and multi-center studies.
What challenges are associated with cryopreservation?
The freezing and thawing process can damage cells, affecting their viability and the accuracy of subsequent measurements.
How does this protocol improve PBMC preservation?
The protocol minimizes cell damage during freezing and thawing, ensuring that bioenergetic parameters are preserved.
Can samples be analyzed at different locations?
Yes, the protocol allows for samples to be collected from various centers and analyzed at a single location.
What types of studies can benefit from this method?
Studies focusing on immune functions, metabolic diseases, and mitochondrial functions can benefit from this cryopreservation method.
