Human PBMC

Understanding and Utilizing the Cornerstone Cells for Immune System Research

Peripheral blood mononuclear cells play an essential role in immunology, toxicology, inflammation, vaccination, and other research into the human immune response. As a cornerstone of discovery, it’s important for researchers in all branches of science to have a deep understanding of PBMC.

We’ve compiled some of our most popular PBMC resources — ranging from in-depth case studies to thought-provoking blog posts to detailed research protocols — into one in-depth guide. Browse the materials below to get tips and insights from our immune cell experts.

Using a Recall Antigen Assay as a Tool for Understanding Immunity (Case Study)

While there is no industry-accepted protocol for measuring PBMC functionality, it’s an important test that should be conducted for quality control.

We needed a reliable, reproducible way to measure the functionality of our cryopreserved PBMC, so we developed a custom assay using recall antigens to understand the in vitro activity of our cells. By testing PBMC for immune response to several different antigens over time, we intended to better understand an acceptable range of variation in recall response from PBMC samples from the same donor over time.

What Are Irradiated PBMC? (Blog Post)

Sometimes researchers need access to the components and benefits of normal PBMC, but don’t want the cells to proliferate. That’s where irradiated PBMC come in handy.

Irradiated PBMC are normal PBMC that have been exposed to radiation from a cesium 137 source to create enough DNA damage that they can no longer divide. The irradiated cells are still alive and can produce cytokines and other soluble factors, but they cannot proliferate.

How Fresh Are Your PBMC? (Case Study)

Post-Thaw Cell Viability chart

When ordering human or animal blood cells for research, many scientists subscribe to the adage fresh is best. But just how viable and functional are those “fresh” PBMC you ordered after sitting out of the body for 24 hours or more?

How does the timing of isolation and cryopreservation following blood sample collection impact cell viability and functionality? See the results of our experiments designed to put this freshness myth to rest.
