Abstract: The present invention relates to primers for the universal amplification and detection of Archaea, which primers are designed based on a multiple sequence alignment of Archaea Type II chaperonin (thermo-some) genes. For detection of Archaea having templates with a GC content of below 60%, primers are designed so that inosine residues are found at degenerate positions. For amplification of higher GC content templates, degenerate positions are replaced with specific nucleotide bases found in the high GC organism. The primers are useful for detecting, identifying and quantifying Archaea in a sample and for determining a phylogenetic relationship of a test Archaea organism.

Abstract: Prognostic methods useful in assessing patients who have received a transplant and reagents that can be used to carry out those methods are provided. The inventions are based, in part, on our analysis of gene expression in renal allografts and clinical parameters, i.e., variables associated with the donor, the recipient and/or the graft. The genes that can be assessed include those encoding agents that mediate inflammation, immune activation, and cell death (we may refer to these genes as “inflammatory”, “immune” or “cytoprotective”). Surprisingly, the levels of gene expression could predict the occurrence of DGF, AR, and the quality of later graft function even when analyzed shortly after (e.g., after vascular anastomosis and tissue reperfusion). We also found that clinical parameters available at the time of transplantation correlate with decreased graft health and can be considered in combination with gene expression to evaluate a patient's risk for an adverse outcome.

Abstract: Disclosed are methods of selecting phage encoding a target binding protein. The methods can include forming a mixture comprising a plurality of diverse display phage, a target, and a support, and forming phage immobilized to the support, each of which comprises a phage which binds the target and the target immobilized to the support. Phage that do not bind to the target are separated. Host cells are contacted with the phage immobilized to the support via binding to the target so that the host cells are infected by the phage immobilized to the support. Replicate phage are produced from the infected cells in the presence of the target immobilized to the support, thereby forming replicate phage immobilized to the support via binding to the support. Replicate phage that do not bind to the target are separated. Host cells are contacted with the replicate phage immobilized to the support.

Abstract: Described are methods and means for enhancing enzyme activity toward insoluble substrates. This is achieved by means of in vitro compartmentalization in which an insoluble microparticle functions both as the enzyme substrate and as a structure for negative selection. Enhanced enzymes expressed from a microparticle-linked polynucleotide library preferentially degrade the microparticle releasing specific gene variants into solution. Gene variants encoding less active enzyme variants remain linked to the microparticle and may be removed through centrifugation, thus enriching the polynucleotide library for more active enzyme variants. These methods may be used to enhance cellulase and ligninase activity toward insoluble cellulosic biomass.
