Cambinol Inhibits JCPyV Infection

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cambinol (Sigma) was resuspended in DMSO to a stock concentration of 1 mM. For the Cambinol experiments, cells were first infected with purified JCPyV in serum-free media (SFM). After 2 hr virus inoculum was removed and cells were washed with 1X PBS, then complete EV-depleted media with 10 μM Cambinol or a volume-matched vehicle control was added. At 6 days post infection (dpi), additional media with drug or vehicle control was added to cells at the same final concentration (96w format – 50 μL; 24w format – 0.5 mL).

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.
