Point and Interval Estimates of IC_50 by Line Approximation
Abstract
When computing IC_50 in experiments which assess the inhibitory effect of tested compounds or physical agents, one is often restricted by a low number of measurements. This paper shows how to progress when only limited data are available. In these cases, a line approximation for the practical computing of IC_50 appears as the most suitable method. In this study, we focus on how to solve the problem of the insufficient number of x-axis points n by optimizing linear regression. Our conclusions are also demonstrated on real data from medical biochemistry.

Disclaimer/Regarding indexing issue:
We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
