General description

The Transcreener® GDP TR-FRET Red Assay is a competitive immunoassay for GDP with a far-red, time-resolved Förster-resonance-energy-transfer (TR-FRET) readout. Because it is highly selective for GDP, the assay can be used with any enzyme that converts GTP to GDP, regardless of what other substrates are used. Examples of enzymes include GTPases and fucosyltransferases. The Transcreener® assay is designed specifically for high-throughput screening (HTS), with a single-addition, mix-and-read format. It offers reagent stability and compatibility with commonly used multimode plate readers. The generic nature of the Transcreener® HTS assay platform eliminates delays involved in assay development for new HTS targets and greatly simplifies compound and inhibitor profiling across multiple target families.

The Transcreener® GDP TR-FRET Red Assay provides the following benefits:
  • Accommodates GTP concentrations ranging from 0.1 μM to 1,000 μM.
  • Excellent data quality (Z′ = 0.7) at low substrate conversion (typically 10–30%).
  • Overcomes the need for time-consuming, one-off assay development for individual members within a group transfer enzyme family by using a single set of assay reagents that detect an invariant product.
  • Time-gated detection method largely eliminates interference that can result from prompt fluorescence of test compounds.
  • Far-red tracer further minimizes interference from fluorescent compounds and light scattering.

Megakaryopoiesis represents a multi-step, often unclear, process leading to commitment, differentiation, and maturation of megakaryocytes (MKs) that release platelets. To identify the novel genes that might help to clarify the molecular mechanisms of megakaryocytopoiesis and be regarded as potential candidates

The pathway of spermatogenesis involves the conversion of diploid stem cells (spermatogonia) to tetraploid primary spermatocytes, followed by meiosis and two cell divisions, first forming diploid secondary spermatocytes and then haploid round spermatids. Differentiation of round spermatids results in spermatozoa

Injury to kidney podocytes often results in chronic glomerular disease and consecutive nephron malfunction. For most glomerular diseases, targeted therapies are lacking. Thus, it is important to identify novel signaling pathways contributing to glomerular disease. Neurotrophic tyrosine kinase receptor 3
