The titer detection of polyclonal antibody serum.

Exploring the expression characteristics of FcμR in small intestinal lymph nodes of bactrian camels can lay the foundation for further revealing the function of FcμR. The FcμR expression characteristics were systematically analysed by using prokaryotic expression, antibody preparation, immunohistochemical staining and statistical analysis. FcμR positive cells were mainly located in the lymphoid follicles and their numbers decreased in the order of duodenal lymph nodes, jejunal lymph nodes and ileal lymph nodes, and the number of positive cells was statistically significant between different intestinal segments (P
