in the equation Y=mX+C, Here i got zero(0) m value then how to calculate unknown sample concentration based on standard curve.

Tutorial : Extrapolate protein concentration using Standard Curve in Excel - Part4

4) Calculate unknown. Initial data consist of response (signal) of different concentrations of standard and response of unknown sample. 1) Calibration curve.
Feb 10, · I have a set a data generated by a biological assay. The data consists of a set of standards and 33 samples. I use the known concentration of the standards to make a standard curve in Excel. Is there a way to calculate the concentrations of the unknown samples, based on the standard curve?

You need a minimum of three points on the calibration curve. The concentration of unknown samples is calculated by solving this equation for C using the.

How to calculate unknown concentration from standard curve in excel - Jan 03, · Enter data for a calibration curve in excel; Make a calibration curve with linear regression trend line; Display the linear regression equation of the line on the graph; Display r 2 value of the regression line on the graph; Calculate the slope and intercept for the regression line using formulas; Calculate the concentration of unknown samples using the equation y = mx + c. 1. Check the protocol booklet to determine whether a standard curve is required for your kit. Standard curves are usually required if you're looking to use the kit for quantitative measurement of concentration (rather than semi-quantitative or qualitative analysis). 2. Measure the signal on a range of known concentrations of a standard. Jan 19, · 2) In A3, enter an x. 3) In B3, enter the formula =$A$1*A3+$B$1. 4) In D3, enter a y. 5) In E3, enter the inverse formula = (D3-$B$1)/$A$1. You can stop at this point if you want. At this point, you can enter different values of x into A3 and get the corresponding y values just as fast as you can enter values into A3.
