A long time ago in a land far away, Scopalamine/Atropine were used to prep a person for anaethesia to prevent secretions buildup in bronchial passages. One use in particular, was obstetric delivery. Q1. Would there be signifi...

Re:

Yes capsid proteins can self asemble in solution. I am not sure what you mean by manufactured, but the genes can be cloned in plasmids, and protein can be synthesized without anything else from plamids. Re self assembly: do you have any source material handy, something I can look at that might expl...

b cells and active immunity

I have a question about developing active immunity. Upon recognizing some antigen, B cells are stimulated to divide into either plasma cells or memory cells. My question is how Memory cells are 'chosen' for the job. I understand that they're clones by process, but is there a signal that picks specif...

some general capsid questions

What kind of proteins are the capsid shells made of?

Will a collection of capsid proteins in soln' generally form an icosahedral (or other geometric shape, depending on protein..) shape; Will they from encapsulating shapes on their own?

can capsid shells be manufactured?
