    Also, the cancer cells which don't produce mAb aren't cost effective. They would just form a tumour that would take up nutrients given but wouldn't produce yield.

    I think it is to identify if the cancer cells have fused with the plasma cells or not. If the cell doesn't produce mAb, it hasn't fused with a plasma cell. So it is just a cancer cell and poses risks to the future person using the mAb.

    Suggestion : CIE Candidate numbers

    I just want to suggest that you make a partnership with CIE and collect the candidate numbers of all the users of Xtremepapers. In that way, it will be more scary for a user to do something illegal. Just a suggestion ;)

    And also, how often do you write more than the given space? For me, quite often. And most of the time, the first two sentences I write are just BS :(
