- Ready access to PBMCs.
No need to wait for home-made preparation of large batches. They are already available and characterized for you.

- Experiments can be designed online based on established HLA-types
and antigen reactivity.

- Sizable donor pool facilitates screening for new reactivities and markers.

- Unlimited cell number available for experimentation.

- Continuous access to PBMC of the same donor and of the same bleed permits rapid progress with controlled experimentation.

- Experiments can be readily repeated and extended, e.g. if reviewers ask
for additional experiments.

- Ability to share the same batches of PBMCs with colleagues anywhere helps
collaborative work.

- Assay comparisons and validations are facilitated by access to precharacterized reference samples.

- Availability of positive and negative control samples, e.g., for clinical trials.
