Question 7

You were out in the garage going through boxes when you were bitten by an a spider.You tell the doctor that the spider was tiny and black,causing the doctor to think perhaps that it was a black widow spider The doctor gives you an injection of antibody to the spider venom to give you immediate protection.The antibody is produced in horses by injecting them with small doses of the spider venom,causing the horse's immune system to make large amounts of specific antibody to the antigen.The horse serum is then purified before being given to humans.
