  • To produce ABs in cell culture you usually create a hybridoma cell line, by fusing the B-Cell to an immortal tumour cell line (as you postulated). This approach does however require you to identify the cells that produce the proper antibody.

    It gets much easier if you know the exact sequence/structure. To learn this (or find a better one) it is also possible to generate libraries of antibody sequences with semi-random hypervariable regions (the part that binds the antibody) using for example phages that will display any protein on their surface area and then measuring the binding affinity! This is called - drum roll - phage display (very creative).

    Alright, enough trivia for now.

    I know a town with I think five or six large furniture (or general household item) stores basically next to each other. Big brands.

    It is probably a combination of factors: The area is easy to reach by car, it’s easy to supply by truck, plenty of space for storage and people actively come there to shop furniture - yes you will be competing with five different stores, but since the customer base travels quite a bit anyway, you’d be stupid to set up shop in a different town. People will walk/drive 5 minutes to check a different store if they already came all this way, but they probably won’t head to a store two towns over just to compare prices.

    A) Evolution is not directed. If a pre-tiger happens to be a more advantageous colour, it will have more offspring. There is no goal.

    B) An orange tiger has the same camouflage from its prey’s point of view as a green one, which is the thing that really matters. There is only one species a tiger is afraid of, and it’s humans. I would wager that the orange also happens to act as a signal colour, both to other tigers and other predators (such as humans). Less run-ins and less territorial dispute sound pretty good.
