Smaller channels always have the best content. It's only annoying that I only found this one 3 days before the first exam😂
Same ahahaha
same hahaha
Underrated. The only video that made me understand this topic
ay dis guy knows what hes on about
Ayyyyyyy
this makes so much sense, thank you! omg biology paper 1 2024 is tomorrow
clearest stuff I've ever seen.
Kay science, your content is next level
Thank you very much, I actually understand this now
Thank you very much for this video so clear
You are welcome!
thanks this is really helpful
Hello past self
Just a bit of a minor mistake i spotted. The mobile antibodies in the reaction zone which do not bind to HCG (since not all mobile antibodies in the reaction zone bind with HCG even if the woman is pregnant ) binds to the immobile antibodies in the control window. The antibodies in the control window are only specific to the antibodies from the reaction zone not HCG
What does it mean when antibodies are specific to antibodies?
Out of curiosity, does anyone know how we get the monoclonal antibodies to be specific to HCG? I thought antibodies were only specific to the antigens on pathogens?
I don't know if I'm being confusing with this question
For monoclonal antibodies - they are made using tumour cells and a lymphocyte - most of the time, in labs they inject the antigen into mouses which produces antibodies (from lymphocyte) as an immune response - the memory cell (lymphocyte) will be extracted and then combined with a tumour cell making many monoclonal antibodies specific to a cell or whatever as long as it has a antigen. So for HCG... hope this helps
@@shahzarbukhlaw5963 Thank you, this does help=) When I wrote this, I couldn't understand why HCG was setting off its immune response; to me it couldn't be pathogen, it was just a regular cell! I didn't think about their proteins, or that it's completely foreign 🤦my brain must have failed for a minute
@@OneOfYourFrenchGirIs no problem - glad it helped
yo man this is crazy
