Ubpbio 100X RELAYTR Europium/Cy5 Ubiquitin Mix, 200 x 20 µl Reactions

Time resolved (TR)-FRET offers a sensitive, low background, stable and homogenous assay for determination of protein ubiquitination. Europium-ubiquitin and Cy5-ubiquitin are a pair of modified ubiquitin suitable for TR-FRET assays to assess formation of polyubiquitin chains, thereby reporting the activity of E2 and E3 enzymes in the reaction. The concentration and molar ratio of europium-ubiquitin and Cy5-ubiquitin in the RELAYTR Europium/Cy5 Ubiquitin Mix are optimized to achieve excellent signal-to-background ratio in ubiquitination reactions. Optimization of protein concentrations is often necessary to achieve a desirable signal-to-background ratio. Typical protein concentration ranges are: UbE1 (10-30 nM), E2 (25-250 nM) and E3 (10-250 nM).Reaction time is usually 1-3 hours in kinetic or end point assay.

Medchemexpress LLC Fenbendazole-d3 | 1228182-47-5 | 99.70% | 5 MG

Fenbendazole-d3 is a deuterium-labeled version of Fenbendazole. It acts as a HIF-1α agonist, stimulating the HIF-1α-related GLUT1 pathway. Fenbendazole is an orally active benzimidazole anthelmintic agent known for its broad antiparasitic effects. It functions as a microtubule destabilizing agent, leading to cell-cycle arrest and mitotic cell death, and has also demonstrated antitumor activity in mice xenografted with wild-type p53.

Can be used as a tracer
Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
Reverses the inhibiting influence exerted by miR-143-5p on proliferation, colony-forming capacity, and migration in BT-549 and MCF-7 cells at 20 μM for 48 h
Elevates the protein expression levels of HIF-1α and GLUT1 in BT-549 and MCF-7 cells at 10 μM for 48 h
