Abstract: Methods and reagents are provided for determining the activation state of a signal transduction pathway signaling protein. There exists a need in the art for methods that can monitor the efficacy of a signal transduction inhibitor in a patient. Other needs exist for detecting and monitoring certain disease or disorders that are associated with aberrant activation of a signal transduction pathway signaling protein. The present assay provides a highly sensitive assay that is also useful in patient populations in which obtaining a large cellular sample is difficult, for example, neonates.

Abstract: A connector apparatus has a first portion and a second portion. The first portion mounts to an upright that has knobby hand grip protrusions. The second portion provides a connection for a laterally extending cross-member. The first portion interacts with the knobby hand grip protrusions to have a combination of a first degree of freedom permitting motion in one direction, while inhibiting motion in a second degree of freedom. The second portion has a releasable connection to the cross-member, and when engaged, has a degree of freedom of motion about an axis of the second portion cross-wise to the axis of the upright. The second portion has a releasable, retained, pin connector with a quarter-turn lock to prevent accidental disengagement. The connection of the second portion is offset such that when two connectors are seated back-to-back their cross-tie connections stand in substantially the same horizontal plane relative to the ground.

Abstract: A method of expanding double negative T cells in culture is described. The method comprises (a) providing a starting sample comprising DN T cells or precursors thereof; (b) substantially depleting CD8+ and CD4+ T cells from the starting sample; (c) culturing the sample from step (b) with an immobilized T cell mitogen in a culture medium comprising an agent that can stimulate DN T cell growth; (d) washing the cells obtained in step (c) and resuspending in a culture medium comprising the agent without the T cell mitogen; and (e) washing the cells obtained in step (d) and resuspending in a culture medium comprising the agent and a soluble T cell mitogen. The DN T cells obtained by the method are useful in a variety of applications including the treatment of cancer, infectious diseases, graft versus host disease and autoimmune disease.
