This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

This seems easily testable. – Frank Nov 4 '12 at 4:34
This question should not be receiving upvotes, it can be tested easily solo in less than 5 minutes. It shows ZERO research effort. – Ender Nov 4 '12 at 11:12
Remember that medivacs can heal your biological protoss units. – mkaito Nov 4 '12 at 13:13
You are right this question is easily testable. Does this question not have value despite that? – Justin Tanner Nov 5 '12 at 7:19
@JustinTanner The SE network is predicated on some basic premises. One of those is, "Do your homework". As it applies to Arqade, that means that anything that would be simple to try yourself, such as this question, is frowned upon. Remember, we're here to help, but you have to help yourself, first. – Frank Nov 5 '12 at 18:00

SCVs can repair anything that is deemed 'mechanical', Terran Buildings are mechanical, Protoss buildings are not.

SCVs cannot repair non-terran structures. They can however be used to repair a variety of Protoss units (Hit Points only, NOT shields):

  • Probe
  • Stalker
  • Sentry
  • Immortal
  • Colossus
  • Observer
  • Warp
  • Prism
  • Phoenix
  • Void Ray
  • Carrier
  • Interceptor
  • Mothership

For completeness, here are the list of Terran units that an SCV can repair too:

  • SCV (note that SCVs can also be repaired by medivacs)
  • MULE
  • Hellion
  • Siege Tank
  • Thor
  • Viking
  • Medivac
  • Raven
  • Banshee
  • Battlecruiser
  • Point Defense Drone
  • Auto-Turret
  • All Terran Buildings

SCVs can not repair anything from Zerg, sorry (although if a zerg player uses neural parasite on a mechanical unit, it can be repaired by an ally's SCV or an SCV that is also NP controlled).

No you can't but still there is great synergy between Protos and Terran.

SCVs can repair the HP (not shield) of friendly Protos units except Zealot, High Templar and Dark Templar. To heal these biological units, you can use Medivacs.

@Ender - my bad. I changed the answer to more appropriate. – iber Nov 4 '12 at 13:37
