Antigen-binding abilities of anti-nephrin antibody are prescribed by signal sequence of expression vector in genetic immunization

Background Nephrin is an essential protein for maintaining the normal structure of podocyte foot processes and the glomerular filtration barrier. To analyze the mechanism of proteinuria and nephrotic syndrome, we previously reported on a new method of producing polyclonal anti-nephrin antibody by genetic immunization. In the present paper, we investigate the effect of signal peptide sequence cDNA on the characteristics of polyclonal anti-nephrin antibodies induced by genetic immunization.
