In the classic peptidergic neurosecretory system of vertebrates the neurohormone oxytocin is associated with the carrier protein neurophysin. By using small gold particles (3 to 12 nm) in the protein A-gold technique, both the hormone and the carrier-protein will be labelled, while larger particles (20 nm) label only the neurophysin. To bind the latter particles, a greater number of Fc-regions of antigen-IgG-complexes seems to be necessary.
在脊椎动物经典的肽能神经分泌系统中，神经激素催产素与载体蛋白神经垂体素相关联。通过在蛋白A-金技术中使用小的金颗粒（3至12纳米），激素和载体蛋白都会被标记，而较大的颗粒（20纳米）仅标记神经垂体素。为了结合后一种颗粒，似乎需要更多数量的抗原-IgG复合物的Fc区域。
