Many initiatives led by worldwide scientific networks are currently being launched to decipher cellular mechanisms involved in SARS-CoV-2 cellular entry. For example, a recent study has identified 332 high confidence SARS-CoV-2-human protein-protein interactions (Gordon D.E. at al. “A SARS-CoV-2-Human Protein-Protein Interaction Map Reveals Drug Targets and Potential Drug-Repurposing” (March 2020) bioRxiv). All these efforts are aimed at rapidly discovering antiviral drugs with proven efficacy, and at developing vaccines to prevent COVID-19 outbreaks. This crisis also enables pharma & biotech companies to reposition their existing antiviral drugs (Harrison C. “Coronavirus puts drug repurposing on the fast track” (Feb. 2020), Nature). In this post, we’ll introduce new, recently released in vitro assays and SARS-CoV related chemical compounds and compound libraries to support COVID-19 early phase drug discovery projects.
Neuronal polarity is essential for the proper development, growth, and physiolog
y of neurons. Within neurons, microtubules (MTs) and motor protein polarities are required for establishing and maintaining neuronal polarity. However, unanswered questions remain: 1. Why are some cytoplasmic molecules in axons but not dendrites? 2. How do MAPs become compartmentalized differently in each type of neurite? 3. Why does a neuron have a single axon but multiple dendrites?5
To help you, the researcher, to answer these questions (as well as many others regarding MT functions in the central nervous system!) for a number of years now we’ve been providing a reliable range of kits by Cytoskeleton Inc. Their highly useful reagents include the Signal-Seeker Enrichment kits for quantifying levels of endogenous PTMs such as acetylation, tyrosine phosphorylation, ubiquitination, and SUMOylation, as well as purified cytoskeletal proteins (e.g., actins, tubulins, kinesin and dynein motors) and functional assay kits to measure the activities of these same proteins.

Monoclonal antibodies (mAbs) are used as immunotherapeutics to
treat cancer and other diseases, and either aim to induce target cell destruction or immune cell activation. After binding to their cognate antigens, mAbs engage Fc gamma receptor (FcγR), localised on the surface of the Immune cells, and identified by many research groups as regulator of mAbs activity. To help researchers working on immunotherapeutic mAbs development, BPS Bioscience have developed a new CHO K1 cell line stably expressing full length human FcGR2B.
