After 3 days of incubation at 37 °C under a 95% air/5% CO2 atmosphere, cell aggregates were formed. For experiments with cells alone (ФV = 0), the same protocol was followed except that the addition of MPs was omitted. Preparation of coated glass substrates for cellular assays ...
After three washing steps with PBS/0.1% (w/v) BSA, bound samples were detected using Ultra-TMB (100 μl/well, ThermoFisher) as the substrate. The reaction was stopped after 10 min by addition of 100 μl 0.2 M H2SO4, and the absorbance at 450 nm was measured using an...
This reduction did not occur if prostaglandin E 2 (PGE 2 ) was present. When 5-bromo-2鈥 -deoxyuridine (BDU) was injected into 4-day old mice, newly formed TRAP+OC nuclei became labeled 1 day later; these bones were then cultured with Ind for 1 day. TRAP+OC and newly labeled TRAP...
