slope-ratio assay for calculating relative potency

Created: Sep 25, 2020 06:17 PM  |  Last Modified: Jun 8, 2023 5:21 PM (2467 views)

Hi,

 

I am trying to analyze the relative potency of different samples. Parallelism test doesn't work this set of data. I was suggested to use slope ratio assay. Can anyone guide me how to do that? The figure is attached below.

 

Thanks,

HY

Can you fit a linear model and test parallelism?  

Maybe try a log10 transform of time, and then fit a 3p model for testing parallelism?
