main idea: the transgenic animals provide alternative methods to produce therapy proteins
structure:
p1. therapy proteins became popular in terms of number and frequency and the existing 2 ways of produce the proteins
-since 25years ago, first case
-purify from blood: 1. cost high 2. contamination 3. low production
-produce by yeast and bacteria: low cost but hard to purify, and no post-translations
p2.merits and disadvantages of the transgenic animals and the evaluation of the author
-post exist in milk of transgenic animals, number of experiment animals is half of pronuclear injection , 40g/l high,
-? only when lactation begins can get the proteins & genes from outside impact some important functions of animals
-summary: demand>supply in the near future, so the method can provide alternative resource of the proteins
new words:
efficacy: 功效
notwithstanding: 尽管如此 adv, prep, conj
