Help please!

[MACKENZIE J.]

I have a few questions that are begging to be answered.Can anyone out there
help please?
1:-How many structural proteins does Coxsackie virus have?
2:-Are HIV-1 and HIV-2 the same virus?
3:-For what virology technique are plasmacytoma (myeloma?) cells comonly used?
4:-What is the usual source of complement for a complement fixation test?

Any help with these would be greatly appreciated.
Thank You
