While it is known that female bottlenose dolphins can spontaneously produce milk if a calf is present, the practice is not well documented and aquarium staff are carefully watching the process.
It also turns out that they're made stable in these environments like milk and mucus secretions because of this secretory chain which is wrapped around it.
同时,连接抗体还可以,使抗体在像乳汁或是粘液分泌物,这样的体内环境中保持稳定,因为分泌循环系统可以将抗体包裹在内
So, milk contains large quantities of this special class of antibodies called secretory IgA.
所以,乳汁中含有大量,这类特殊的,称为分泌型IgA的抗体
