Cell line development – global market drivers, trends and its impact on improving biologics development from early phase to IND during the drug discovery process

19 March 2019 | By

Cell line development is a major step for examining the efficiency of drug discovery, toxicity and in-vitro testing. It reduces time, effort and cost, which minimises the chance of research drugs failing at the clinical trial stage. This stage involves the production of recombinant proteins such as monoclonal antibodies, bi-specific…

Expert view: Three-dimensional cell cultures as predictive tools in early drug discovery

6 December 2018 | By

Three-dimensional cell cultures (spheroids, organoids) are becoming widely used as a new predictive tool in early drug discovery. The use of 3D cell cultures is believed to provide a more physiologically relevant response than monolayer (2D) cell cultures because they closely mimic the extracellular matrix and cell-cell interactions that occur…

A high-throughput approach for measuring intracellular ATP levels to access compound-mediated cellular toxicity

30 November 2018 | By , , ,

Many drugs fail in clinical trials due to toxicity-related issues; therefore, drug-mediated cellular toxicity should be determined at an early stage in the drug discovery value chain. There are many assay systems that can be utilised to measure cellular toxicity. In this article we demonstrate that intracellular ATP concentrations are…

Application note: Production of human induced pluripotent stem cell-derived cortical neurospheres in the DASbox® Mini Bioreactor System

29 November 2018 | By

There is substantial interest in the scientific community in using human induced pluripotent stem cell (hiPSC)-derived neural cells to study basic mechanisms of brain development, neuronal function, and drug-induced effects. In vitro-generated brain organoids are promising models, because they show a remarkable degree of maturation and can be kept in…

Application note: Sensitive fluorometric quantification of DNA in microplate format

29 November 2018 | By

This technical note demonstrates the feasibility of using the Thermo Scientific™Fluoroskan™ or Fluoroskan FL instruments with the Invitrogen™ Quant-iT™ dsDNAhigh-sensitivity assays. Sensitive and specific quantification of double-stranded DNA is carried out in microplate format. This is part of a series of technical notes aiming to help customers choose the best…

Application note: A novel solution to expedite antibody discovery

29 November 2018 | By

With breakthroughs in molecular engineering and antibody humanisation, monoclonal antibodies (mAb) are one of the fastest-growing classes of biopharmaceuticals for multiple clinical indications including cancer, cardiovascular disease, autoimmune disorders and infectious disease. Most therapeutic antibody candidates are initially generated using hybridoma technology or primary B-cell screening after antigen immunisation.

Using bioactivity profiling to support the progression of phenotypic hits

7 September 2018 | By ,

This webinar, held on 28 June 2018, illustrated the optimisation of hits derived from a target-agnostic phenotypic screen, using a strategy based on combining bioactivity profiling and reference compound characterisation. Keynote speaker Arsenio Nueda, Head of Molecular Biology at Almirall, responded as follows to questions posed during the webinar.
