The Human Serum Metabolome
As part of our objective to systematically characterize the human metabolome and advance the fields of quantitative metabolomics, we present a global metabolic profiling of the human serum. Our experimental results indicated that global metabolic profiling methods can routinely detect more than 4200 different compounds in serum.

A simple, fast and quantitative single-step dead-cell indicator for flow cytometry
We have evaluated a series of new compounds for dead cell stain and identified a new product, SYTOX® AADvancedTM dead cell stain, which demonstrates improved properties over 7-AAD. These properties make the SYTOX® AADvancedTM dead cell stain a simple, fast and quantitative single-step no-wash dead-cell indicator as well as ideal for use in multicolor application requiring DNA content.

Microcarrier based production of cryopreserved cells
The use of cellular assays in drug screening continues to grow with over 50% of primary screens using cell based formats in 2006. The majority of cells used in the drug discovery industry are fresh, using ‘just in time’ batch processing from in house facilities. This process could give rise to a number of issues, namely batch variation, scheduling of cell production and capacity management. We describe the use of microcarrier technology in combination with a suitably configured bioreactor to pro

Smart Solutions in drug discovery
Here we present data on the development of a large scale production process for the provision of two different cryopreserved transiently transfected cell lines. Included is identification of a suitable transfection reagent that is efficient, non-toxic and cost effective. This process has been validated using these two cell lines and two different cell-based assays.

The application of microcarrier technology for the provision of receptor membranes for high-throughput screening
The recent growth in cell use for drug discovery, particularly for high-throughput screening (HTS), has posed a number of challenges including batch performance, cell production scheduling and capacity management in response to the increasing demands for cells and assay components derived from cells (e.g. membrane fractions).

Quality Tools and their Application in the Production of Cellular Reagents for Screening Assays.
The use of mammalian cell based assays in compound screening continues to grow. Over 50% of all screening assays (HTS and HCA) now utilise cells or cell derived reagents.

Single stage reversed-phase liquid chromatography-mass spectrometry for the characterization of triglyceride positional isomers.
The high level of selectivity afforded by RP-HPLC in combination with CID allowed recognition of eight groups of TAG positional isomers. Development of UPLC approach has reduced the run time by half while maintaining separation. The improved method combined with principal components analysis was used to assess the extent of variation of major TAGs in subcutaneous and intermuscular pork fat from four different locations of adipose tissues.

Protein array-based screening of autoantibody signatures
The evidence for an association between autoimmune diseases and chronic HCV infection has been clearly established. To this aim, a protein array was employed to analyze serum samples of HCV patients w/wo autoimmune complications, of patients with autoimmune hepatitis but not infected with HCV and of healthy donors as controls. A panel of autoantigens able to discriminate among the three groups of patients was identified for potential use as biomarkers.

PROTEOME WIDE PLASMA PROFILING USING ANTIBODY SUSPENSION BEAD ARRAYS
A newly developed antibody suspension bead array assay allows for a systematic and high-throughput plasma profiling. This microtiter based assay uses antibody-coupled beads for a multiplexed analysis of minute amounts of directly labelled samples. The key requirement of a?nity reagents towards all human proteins is met by the Human Protein Atlas project.

Clinical Evaluation of human embryonic stem cells (hESCs) induced with directed differentiation to gonadotrope cells to cure vasculogenic impotency and to improve coital frequency in males. An open st
This work demonstrates the clinical efficacy, tolerability and safety of patient-syngenic hESC induced with directed differentiation to gonadotrope cells. Hypothalamus transmits gonadotropin releasing factor to pituitary that sets off LH and FSH to Sertoli cell and Seminiferous tubule resulting Leydig cell to produces testosterone. This potential offers a rationale to evaluate hESCs to cure patients with vasculogenic impotency and to improve coital frequency in males.
