From: Development of nanobody-horseradish peroxidase-based sandwich ELISA to detect Salmonella Enteritidis in milk and in vivo colonization in chicken

Scheme 1

Graphic abstract of the developed sandwich to detect S. Enteritidis in practical sample. a Nbs were screened by the phage display platform. b SE-Nbs and SE-Nbs-vHRP were produced by E. coli expression system and eukaryotic expression system in HEK293T cell, respectively. c Detection practical sample with the developed sandwich ELISA
