Interesting and potentially valuable in situations when "very large-scale manufacturing  of antibodies" (as in the case of pandemics) is required - but first you must identify your high affinity monoclonal Ab. Not always that easy!

Hi
 
I just came across this review in Chemistry world (from a paper in ProcNatAcadSci), which describes the production of gram quantities of IgG antibodies from tobacco plant leaves.
 
This may be of interest to two groups; firstly those who remember the history of raising antibodies for the NHS in the farmyard (literally).
Secondly, it may appeal to any 'soft pinko lefties' among us who don't really like the idea of sacrificing hoards of mice or other furry creatures to run our immunoassay industry.  Sorry if I get my phone tapped for that thought.
 
The antibodies apparently are intact but lack the ability to bind Fc receptors, which may initially hinder pharmacological uses. However I would imagine that could be an advantage in immunoassays by removing potential interference from rheumatoid factor etc.

Apologies if you are doing this already.
 
Regards
Steve
