You need to log transform your X-axis variables; X is log (concentration) and use non-linear regression analysis in GraphPad prism. I am also attaching the snapshot of GraphPad prism page, where.
GraphPad Prism 9 Curve Fitting Guide Example Simple logistic regression
For example, setting the classification cutoff to 0.5 is common (and default for simple logistic regression in Prism), and means that if the model predicts a probability of success greater than or equal to 0.5, then that prediction is classified as a "success" (Y=1), while if the model predicts a probability less than 0.5, it will classify it as.

When a categorical variable is inserted in a regression model as a predictor, Prism automatism encodes this variable using "dummy coding". This process generates (behind the scenes) an number of new set equal at the number on floor of the original criteria variable minus one.

When a variable is categorical (survived/died, male/female, 1st/2nd/3rd class, etc.), we can encode those responses as a set of 0s and 1s in a process called dummy coding (there are other coding techniques, but dummy coding is probably the easiest to understand).

Odds = (Probability of success)/ (1 - Probability of success) For example, let's say there's a 75% probability of success, the odds would then be calculated as: Odds = 0.75/ (1 - 0.75) = 0.75/0.25 = 3 Commonly, we would say that "the odds are 3:1" (read "three to one").

1. Create a data table From the Welcome or New Table dialog, choose to create an XY data table. Be sure to select the option "Enter and plot a single Y value for each point." Simple logistic regression in Prism currently does not allow for replicates in subcolumns.

Analyzing radioimmunoassay (RIA) or an enzyme-linked immunosorbent assay (ELISA) data is a two-step process: Prepare and assay a set of "known" samples, i.e., samples that contain the substance of interest in amounts that you choose and which span the range of concentrations that you expect to be present in your "unknown" samples.
GraphPad Prism 10 Curve Fitting Guide Example Multiple logistic regression
The goal of logistic regression is to perform predictions or inference on the probability of observing a 0 or a 1 given a set of X values. In the following, we write the probability of Y = 1 as P (Y=1). Logistic regression fits a linear regression model to the log odds. The odds are defined mathematically as P (Y=1) / P (Y=0).
