SELECTIVE ACCESS TO CRYOPRESERVED SAMPLES

摘要

Methods and apparatus for selectively accessing a portion of a sterile cryopreserved sample are disclosed. The apparatus may include a container configured to receive the cryopreserved sample and having a first portion and a second portion, a heat sink chamber surrounding the first portion of the container, and a heat source adjacent to the second portion of the container. The chamber may be configured to maintain a non-accessed portion of the sample in a cryopreserved state. The heat source may be configured to separating an accessed portion of the sample from the non-accessed portion of the sample while maintaining the viability of the accessed portion while the non-accessed portion is maintained in the cryopreserved state.
