Indicate which of the following statements regarding haptens and carriers are true. 

#Unit 4. Cell Communication and Cell Signaling
  1. Haptens are large protein molecules such as BSA. 
  2. When a hapten-carrier complex containing multiple hapten molecules is injected into an animal, most of the induced antibodies are specific for the hapten. 
  3. Carriers are needed only if one wants to elicit a cell-mediated response. 
  4. It is necessary to immunize with a hapten-carrier complex in order to obtain antibodies directed against the hapten.
