Hybridoma Production
- Immunise mouse with antigen
- Extract B cells from spleen
- Fuse B cells + myeloma cells = hybridoma
- Hybridoma = antibody ability + immortality
- Select, clone, mass produce
Applications
- Pregnancy test: detects hCG hormone; line = positive
- Cancer treatment: targets cancer surface antigens
- ELISA: detects pathogens or antibodies in blood
- Blood typing: identifies ABO antigens
- Drug delivery: antibody carries toxin to cancer cells
Common Marks Lost
- Saying hybridoma = B cell + T cell (it is B cell + myeloma)
- Confusing mono (identical) with polyclonal (mixed)
- Pregnancy test "detects pregnancy" — it detects hCG
- Saying monoclonal antibodies are vaccines (they are not)
- Not explaining WHY myeloma cells are used (immortality)
