Science Blind Draw Test 2

Last week, me and @nanosesame has piloted the Science blind draw pre-run, this idea was proven to be quite feasible and interesting. So we are trying it for another round. Our last week was about human anatomy, so please feel free to visit our post here and here

Rules:
Science keywords for @nanosesame (Artist) to draw, ideally @nanosesame (Artist) has no idea on this field
Descriptions could be added if @nanosesame (Artist) finds it too difficult
Explanations of @nanosesame (Artist)’s art must be given after the drawing, to verify, as well as to provide knowledge to all the readers.
Add the tag #scienceblinddraw
We are trying to make fuse knowledge with arts, and we welcome others artist to join~ Leave us a tag with #scienceblinddraw so we can see your work~

I recently wrote an article about the Okinawa measles outbreak, and vaccine is the key player. and when we talk about vaccines, it always reminds me of ANTIBODY.

So this round topic will be ANTIBODY, I know it is very difficult for @nanosesame to picture the protein, so my description will be: Antibody is a Y shaped protein than can bind to microbes~
