CHZ868 was synthesized by Novartis and stored at 1mM in DMSO for in vitro use. For in vivo applications, CHZ868 was administered orally at 15 mg/kg twice daily (bid) or at 15, 20, 30 or 40 mg/kg once daily (qd). CYT387, BMS911543 and ruxolitinib were purchased from Chemietek. SAR302503 was synthesized as described(Marubayashi et al., 2010 (link)); these agents were stored at 1mM in DMSO at −20°C.

HepG2 cells (purchased from ATCC-HB-8065) were grown at 4×105 cells/cm2 in Permanox® (Nalge Nunc International) slides for 24 h in the presence of 2 μM AZD1480 or 10 μM of TG101348 (both Selleckchem) or 2 μM of BMS911543 (Chemie Tek) or vehicle before addition of human platelets treated or non-treated with sialidase. Immunofluorescence for anti-pSTAT3 (Cell Signaling Technology) was performed 1 h after platelet addition to HepG2 cells following antibody manufactor’s protocol. After 6 h incubation with humans platelets treated or non-treated with sialidase, HepG2 cells were fixed in 4% PFA, followed by permeabilization in 2% Triton X-100. Cells were incubated for 30 min at 37 °C with 5% goat-serum to block unspecific binding and incubated overnight at 4 °C with a polyclonal anti-human TPO antibody (R&D Systems, USA) followed by secondary AlexaFluo®568 conjugated polyclonal goat-anti rabbit antibody (Invitrogen). Nuclei were visualized by inclusion of 4′, 6-diamino-2-phenyllidole (DAPI) (Invitrogen) in the mounting medium.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
