Summary for Patent: 5,667,985
| Title: | Tissue biopsy cell suspender for cell analysis |
| Abstract: | A tissue biopsy cell suspender device includes a receptacle having a sealable opening. The receptacle contains a sufficient quantity of an aqueous medium to support an enzymatic dissociation of cells from a tissue biopsy sample. The device has a removable closure with a first sealing position and a second sealing position for sealing the opening in the receptacle. The device further includes a frangible container having a sufficient quantity of an enzyme therein to dissociate cells from the tissue biopsy sample. The frangible container is covered with a membrane that is permeable to water and to the enzyme. The frangible container is disposed within the receptacle so that the container is intact when the closure is in the first sealing position and the container is breached when the closure is in the second sealing position. When the frangible container is breached, the enzyme is released to permeate into the medium and for dissociation of the cells from the tissue sample. |
