Compositions and methods are provided for integrating one or more genes of interest into cellular DNA without substantially disrupting the expression of the gene at the locus of integration, i.e., the target locus. These compositions and methods are useful in any in vitro or in vivo application in which it is desirable to express a gene of interest in the same spatially and temporally restricted pattern as that of a gene at a target locus while maintaining the expression of the gene at the target locus, for example, to treat disease, in the production of genetically modified organisms in agriculture, in the large scale production of proteins by cells for therapeutic, diagnostic, or research purposes, in the induction of iPS cells for therapeutic, diagnostic, or research purposes, in biological research, etc. Reagents, devices and kits thereof that find use in practicing the subject methods are also provided.

Provided are a system and methods for selectively inducing expansion of a population of T cells in the absence of exogenous growth factors, such as lymphokines, and accessory cells for research purposes. The cell based expansion system and methods permit the long-term growth of CTLs, preferably human CTLs. In addition, T cell proliferation can be induced without the need for antigen, thus providing an expanded T cell population that is polyclonal with respect to antigen reactivity. Further provided are methods for using the system and methods to screen and identify antigens related to specific diseases or conditions, tumors, autoimmune disorders, or an infectious disease or pathogen, and to identify target molecule for research purposes, or for developing a vaccine based thereon.

A system, method, and computer program product for separating a seed aliquot from a bulk sample and preparing the seed aliquot for downstream research purposes is provided. The system embodiments may comprise a counter device, which is configured to receive at least a portion of the bulk sample and to separate the seed aliquot from the portion of the bulk sample, and a packaging device, which is configured to receive the separated seed aliquot and to dispense the aliquot into an aliquot container. Other embodiments may include a conveyor system for advancing the bulk sample and/or seed aliquot along a conveyance path that may be determined from a research protocol received from an input source. Various embodiments of the present invention may maintain an identity of the seed aliquot as it is advanced along the conveyance path and may selectively subject the seed aliquot to a variety of processing steps in accordance with the research protocol with little or no manual control or supervision.

The present invention provides polymers and methods for increasing the viability of cryopreserved cells after thawing. Thawing cryopreserved cells in the presence of a polymer such as poloxymer P1 88 or other non-ionic polymers is thought to stabilize the membranes of the cells leading to increased post-thaw viability. Such methods may be used in the processing of cells and tissues for transplantation or for research purposes. Other agents such as antioxidants, vitamins, or osmotic protectants may also be added to cells to improve viability.
