Plantibodies are antibodies that are produced by genetically modified plants. They are made by transforming plants with antibody genes from animals, allowing the plants to produce antibodies. The first plantibody was a mouse antibody produced by tobacco plants in 1989. Plants are now used as antibody factories to produce large amounts of clinically useful proteins through their endomembrane and secretory systems. Methods for producing plantibodies include transforming plants and targeting the antibodies to be secreted to areas like the apoplast or endoplasmic reticulum. Plantibodies can be purified cheaply in large quantities from transgenic seeds and may be useful for treating illnesses through clinical trials.

3. What are plantibodies ??
 A plantibody is a Antibody
produce by genetically modified
plant.
 Antibody are part of Animal
immune system, and produce in
plant by transforming them with
Antibody genes from Animals.

4. Cont….
 This was first done in 1989,
with a mouse antibody made
by Tobacco plant.
 Although plant do not
naturally make antibody,
Plantibody have been shown
to function in the same way
as normal antibodies.

5. Antibody factories
 Plant are being used as antibody factories,
using their endomembrane and secretory
system to produce large amount of clinically
visible proteins.
 Antibodies can be expressed in plant as either
full –length molecules or as smaller fragment.

7. Methods for plantibody production
 Using transformation
and translent
expression to introduce
new genes into a host
cell.
 Targetting to the
APOPLASM by the
tagging with a small
peptide sequence.

8. Cont….
 Single molecule added to target the
protein to Endoplasmic Reticulum
(E.R); to ensure correct folding of the
protein.
 Higher protein level obtained in the
E.R and the apoplasm as compared to
the crystol.

9. Purification of plantibodies
 Purification can be purified
cheaply in large quantity
 Transgenic seeds assure
excellent storage properties and
due to limited range of
endogenous proteins in seed,
separation of plantibodies is less
complicated
 There is no risk of srading animal
disease to human as the
antibody produced by plants.

10. Technique for purification of
plantibodies
 Filtration
 Immunofluoresence
 Chromatography
 Difiltration
 Polymer fusion.

11. Evaluation technique for the
Plantibodies:-
 RIA (Radioimmunoassay)
 ELISA (Enzyme linked
immuno sorbant assay)
 Immunofluorence
southern blot analysis.

12. Production cost of Plantibodies

13. Advantage:-
 Large-scale production of plantibodies for
immunotherapy
 Benificial to human, plants as well as
economy.
 No risk of transmitting diseases to human
 Eliminate the toxic compound;

14. Application:-
 Antibodies generated by plant are
cheaper, easier to manage, and safer
to use than those obtained from
animals.
 Treatment of illness such as immune
disorder, cancer and inflammatory
disease.
 Plantibodies are close to passing
clinical trail.
