Lot Release Testing

Sidebar Image

Unprocessed bulk (UPB) is the material collected directly from the bioreactor in which genetically engineered cells grow and produce product. Low levels of adventitious agents such as bacteria, yeast, fungi, molds, mycoplasma and viruses that bypass detection during raw materials testing, may grow to detectable levels under the highly enriching conditions of the bioreactor. At this point in the manufacturing process, it is optimal to test for these adventitious agents and testing of each lot of UPB is a regulatory requirement.
