ELISA a Powerful Technique to Detect and Quantify Specific Proteins or Antigens
ELISA (Enzyme-Linked Immunosorbent Assay) is a powerful technique used to detect and quantify specific proteins or antigens in a sample.
How ELISA Works:
Immobilization: Antigens or antibodies are immobilized onto a solid surface (e.g., microplate).
Binding: A primary antibody (specific to the target antigen) is added and binds to the immobilized antigen.
Secondary antibody: A secondary antibody, labeled with an enzyme, binds to the primary antibody.
Enzyme reaction: A substrate is added to the well, and the enzyme on the secondary antibody catalyzes a reaction that produces a detectable signal (e.g., color change).
Measurement: The intensity of the signal is measured, which is proportional to ...

Dr. Mahdi, thank you for the great video. Could you please share the paper references for the look into the following Biotin reactions? I wanted to learn more about these reactions and try to replicate them in the lab.
Please find below the link for my papers which are about protein immobilization and reaction between biotin and streptavidin onlinelibrary.wiley.com/doi/full/10.1002/admi.202002117 www.beilstein-journals.org/bjnano/articles/10/241 onlinelibrary.wiley.com/doi/abs/10.1002/admi.201801343 onlinelibrary.wiley.com/doi/abs/10.1002/smll.201800131

Do you transfer them To the ground after ?
It's better to leave them in the pot for a few months and when they are big enough, it's time to transfer them to the garden.
Danke schön hübsch

Very helpful, thank you so much. I've subscribed to your channel.

Your blurrry ash
Sir is only fresh seeds will germinate
No, you can also dry and keep them somewhere and plant them whenever you want
@@FunwithDrMahdi thanks sir
How to make this picture on top of all other items.. means "brint to top" for this picture.?? I did what you said, and my picture went behind other pictures in every slide.🥲🥲
When you go to the insert and select the picture, you can move the picture with your mouse to wherever you want
So i just need to water it and wrap it untill germination? I dont need to water again right?
No, you don't need to water it anymore
You should check if the solid is dry. if it is dry then the germination will stop/slow
@@Selahattin-em1uh it did not work since my last comment nothing happened, but can I try germinating with paper towel?
@@finestbird4784 Of course you can. Actually I use that method for propagation most times. But there is a risk that seeds might rot in the paper towel. I hope you can grow it
This is present perfect not past perfect
matsalam ng marami lodz!
Thanks :)
Hello. You forgot the situetion if the ball become diffective during a penalty kick. if the ball does not end up somewhere then the penalty kick is repeated. However, if the ball ends up in the goal post for example and then the ball become diffective, then the match is restarted with a droped ball. thank you!
Good Points. Thanks
I just remembered this in my book thanks 😅🎉
You're welcome
Thanks for this tutorial❤🎉. I need to know how I allow the to play alternately like what I see on Tiktok? Please
thanks for the video!
You're Welcome
Hello and thank you very much for this video! I just have begin my personnal RUclips channel (you can have an eye on it: already 5 videos in one mouth :) ) and I edit with Kdenlive but Shotcut seems very more simple for this kind of multi- windows! Dio you confirm ? Do you know also Kdenlive? :) I'm on Linux Mint :) Thanks for your smile! Cheers from France. Michael
Thank you so much for your nice explanation. It was very helpful and fruitful.
You are welcome!
