Random homozygous gene perturbation (RHGP) can identify and validate any host (cellular) gene target that directly causes a desired phenotype without requiring prior knowledge of the target. The central feature of RHGP is a unique lentiviral-based genetic element, known as a gene search vector (GSV) designed to interrogate the entire genome and identify target genes that cause the phenotype of interest.

The main objective of this work was to develop a surface chemistry which maintains protein function and orientation per unit surface area, regardless of the surface used.

Since the end of the 1990’s, the pharmaceutical industry has seen an increased interest in biologics, especially in the therapeutic areas of oncology and inflammation. Here we present the automation of two assays for the characterization and selection of potent antibody drug candidates. Both assays rely on HTRF® detection. The first assay quantifies the binding affinity of antibodies to their target antigen, on live cells.

Assays that can assess the ability of a biosimilar to act in a manner similar to the original biologic have seen increased interest. This poster describes the use of a non-radioactive luminescent chemistry to simplify the assay process and provide improved data quality.

ELISA is one the most utilized assay formats in biomedical research. Numerous clinical, veterinary, and research assays use the specificity of antibodies to identify a diverse array of analytes from any number of different matrices. This poster details a modular bench top workstation capable of automating the assay process steps of most conventional ELISA assays.

SpectroSens, a multi-channel optical microchip sensor system suitable for rapid, label-free multiplexed detection of a wide range of bio-hazardous agents is presented. Optical chips containing multiple high-precision planar Bragg gratings are exploited as low-cost, robust refractive index sensors.

The conventional antibody screening assay based on antibody-antigen binding has been enzyme-linked immunosorbent assay (ELISA). While tedious and consuming, ELISA has proved sufficient for the identification of antibodies directed against secreted antigens. However, cell surface antigens (e.g. GPCRs) provide challenges for ELISA due to the shortage of soluble antigens and high variability resulting from loss of cells during wash procedures.

Peripheral blood is widely used as starting material for biomarker discovery and validation using molecular biology technologies. The vast majority of currently published transcriptome data is based on RNA derived either from stabilized whole blood or peripheral blood mononuclear cells (PBMCs). Here, gene expression profiling studies and SOPs for fast, easy and specific manual or automated isolation of monocytes directly from whole blood are being described.

Residues 261-273 of type II collagen bound to the MHC class II allele HLA-DR4 play a crucial role in rheumatoid arthritis. The protein–protein interactions between TCR and CII-MHCII complex may therefore serve as targets for the development of new drugs against RA. The aim of this study is to develop a pharmacophore virtual screening followed by molecular docking and dynamics calculations leading to the identification of new TCR/CII-MHCII inhibitors.

We discovered that in vitro high dose of Progesterone (P) together with FGFa, EGF, VEGF, LPS had dual effect on Liver tissue cells: increased multiplication of Hepatocytes and suppressed all non-parenchymal (NP) liver tissue cells and created immune tolerance between two allogeneic mice Liver tissue
