AQA GCSE biology 1 (higher tier)

Inject protein into rat to stimulate rate B lymphocytes to produce antibodies. Obtain rat lymphocytes and combine them with tumour cell to form hybridoma. Hybridoma divides and produces monoclonal antibodies which are specific to the antigen of the virus. Collect and purify antibodies.

How did you find this paper today? I really struggled with the monoclonal antibodies question, I knew how to get them from animals but I had no idea about plants ☹️

I only realised right at the end 😂. What did everyone out for that child with CF having a slower growth rate

any1 know what calculation you had to do for how much extra milk u obtained?

Omdsss tht was acc hard yano ... what did u put for the question abt what molecules make up genes or sumfin i put dna molecules but some smart guy in my year sed it was some sugar substarre of somebing

Divide how much you needed by how much was in 500cm^3 then times by 500. That’s how much you need to drink to get your daily intake. Work that out for the two things and find the difference x

i don't think you have to get them from plant, i think you just inject the PVY into a rat and make monoclonical antibodies from that.

I put down that it's a protein
