Abstract: A mixing container wherein two or more chamber members each contain a material to be mixed. A first chamber member has a threaded port. A second chamber member has a threaded neck which is threadedly receivable in the port to threadedly connect the chamber members. The neck has a terminal opening. A sealing member covers the opening. The first chamber member has a frangible portion which sealingly closes an inner end of the port and which is broken is as the neck bears there against as the neck is threadedly received in the port.

Abstract: A method of predicting the lymphotropic metastatic potential of a solid non-lymphoid tumor. The percentage of cells of each of a plurality of representative samples of the tumor which express lymphoid gene products is determined.
