Frequently Asked Questions
What is the difference between pooled and single-donor products?
Pooled products combine material from multiple donors, which averages out donor-to-donor variation and gives large, uniform lots. Single-donor products come from one donor: their properties trace to that donor and can differ more between lots. Studies that need a single, well-characterized source, such as one complement lot carried through a clinical trial, use single-donor material.
How do I reconstitute lyophilized human serum products?
Lyophilized human serum products may be reconstituted by bringing the vial to ambient temperature then resuspending in sterile water equal to the volume on the product label. For lyophilized complement products, resuspending in a volume less than the label volume will increase complement potency, useful in applications requiring increased complement activity.
