Thank you for your suggestions, I am sorry that http://www.nabble.com/file/p21168216/ds2_panelA_p8_B3_dil4x.csv ds2_panelA_p8_B3_dil4x.csv I forgot to include the concentration of Standard to use. the first standard (A1, A2) is 67000 and dilution series is created by diluting it 1/3. i am reposting the full Absorbance data once again to have a full idea about the output file created by the ELISA software. I am also uploading the sample file for a better understanding, serum samples in this case are diluted 4 times
