What technologies are used in the antibody design process?

answer:

single-use technologies.

info about it: "single use technology started with the use of membrane filters, which have been in use in biopharmaceutical processing since the earliest days of the industry and their use can be traced to the mid-1970s, when the united states food and drug administration required non-fiber releasing filters to be used in the production of injectables."

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

the unequal cytoplasmic division that  results  in  one egg  and three polar bodies ensures that a fertilized  egg has  ample nutrients  forits journey  to  the uterus.
