Analysis of antibodies from whole-cell immunization by a tANCHOR cell-based ELISA

Abstract

Monitoring specific antibodies derived from whole-cell immunization through cell-based ELISA methods poses challenges due to humoral responses against various cell proteins. In this report, we outline a technique involving pre-adsorption on cells to remove undesirable antibodies from immune serum. This step provides the subsequent monitoring of antibodies specific to the targeted antigen using a tANCHOR-based ELISA. Notably, this approach accelerates result acquisition, eliminating the necessity to purify the expressed antigen or obtain a customized peptide for coating assay plates.
