| Hi everyone, I'm a newbie with ELISA and I have a basic question. I'm working with mouse serum in order to quantify IFN-gamma and my supervisor asked me to dilute 2x the sample in assay diluent. So once I get my OD, in order to calculate the original concentration : Do I have to multiply the OD by 2, or do I have to multiply the calculated concentration by 2? Thank you for your help Dusan |

| multiply the calculated concentration off the standard curve by 2. Generally you dilute so that it will be in the OD range for the standard curve |
