Hi Amir

Inter refers to the variation between separate runs of the same ELISA e.g. same assay run on different days with the same samples and standards/controls using the same conditions, instruments, etc.  Intra refers to the variation  between replicate samples in a single ELISA run.  Intra gives an indication of the assay's reproducibility while inter gives an indication of the assay's robustness.

Hope that helps.
