Should I work with IC50s or pIC50s?

Posted on June 13, 2016 by Gary Mirams

When you are expressing how much a drug inhibits something, it’s common to fit a Hill curve through a graph of concentration against % inhibition as shown here: In our case this is often ‘% inhibition’ for a given ionic … Continue reading →

If computational biologists did astronomy…

Posted on September 12, 2015 by Gary Mirams

Here is a cheeky post along the lines of Can a biologist fix a radio? (well worth a read). The discovery that Pluto wasn’t the size we expected got me thinking about how we would have tackled it. So in … Continue reading →
