One-step sandwich ELISA delivers specific and sensitive results in 90 minutes.

We have developed a microfluidic device capable of hydrodynamically trapping cells over polymer lines which encourage 1D migration based on topographical cues. These lines have been fabricated with both femtosecond laser ablation and dewetting/stamping. This type of precise control will allow precise microfluidic assessment of potential drug targets to limit cancer cell migration.

Understanding the molecular details of drug-target protein interactions is a critical component of the drug discovery process in the modern pharmaceutical industry.

Immunotherapy, also called biologic therapy or biotherapy, stimulates certain parts of the immune system to fight diseases such as cancer. Important drug targets in immunotherapy include: Co-inhibitory receptors, such as PD-1/PD-L1, CTLA-4, LAG3, Tim3; and co-stimulatory receptors, such as GITR, CD40, OX40, 4-1BB.
Current approaches to assaying these targets are cumbersome and variable. Here we offer an improved in vitro bioassay approach.

We describe the application of back-scattering interferometry (BSI) to the characterization of small molecule ligand binding to human GPR39 (a GPCR targeted for type-2 diabetes therapy) overexpressed in crude membrane fractions in free solution, including how BSI-derived affinity and functional assay-derived potency correlate for compounds of varying scaffolds.

This study aimed to identify and characterize strain specific essential protein targets, which will eventually help in the identification of druggable proteins in two strains of MRSA by using different Bioinformatic tools and databases. We adopting a subtractive genome approach within the domain of Computational Biology.

The primary function of this application note is to demonstrate automated methods for a HTS-ready universal methyltransferase activity assay.

Epigenetic processes are attracting considerable attention in drug discovery as their fundamental roles in controlling normal cell development and contributions to disease states become more clearly defined. This work combines a fluorescence-based assay with liquid handling and dispensing instrumentation and a multi-mode reader which can be used to monitor the biological activity of the histone methyltransferase (HMT) G9a, a model system.
