Visualising actin dynamics has always been a real challenge. For this reason, Spirochrome have developed unique probes based on the much used SPY probes technology, enabling you to label very fast actin dynamics.
These probes present many advantages:
- They do not require any genetic manipulation, transfection or overexpression of fluorescent proteins.
- They are based on bright, photostable fluorophore, far superior than fluorescent proteins.
- They’re available under far red (Abs/EM: 696/718 nm) fluorophore (SPY700-FastAct™) or orange (Abs/EM: 555/580 nm) fluorophore (SPY555-FastAct™) or far red (Abs/EM: 652/674 nm) fluorophore (SPY650-FastAct™).

2 populations of primary human endothelial cells were separately labeled with SPY595-DNA or SPY505-DNA.
After the DNA labeling, the 2 populations were trypsinized, mixed together, stained with with SPY700-FastAct and imaged.
