Allocell AF represents a new class of allograft engineered for enhanced intra-operative handling and increased biologic responsiveness at the defect site.  Allocell AF is designed with broad, augmented bone fibers that maximize the surface area, allowing the fibers to better fill the defect site. Each lot of Allocell AF undergoes an in vivo rat osteoinductive (OI) potential testing, which is the gold standard in verifying osteoinductivity of the demineralized allograft.  Allocell AF offers osteoinductive and osteoconductive entangled fibers that creates cellular highways for easier cell attachment and proliferation.
