Antibodies Definition and 11 Threads

THIS POST TITLE IS MISLEADING. I paraphrased/lifted from the jpost. com article but did not read the research article. @Ygggdrasil graciously points out the error in post #3 below. Thanks...

I have a doubt. It is said that antigens detected by macrophages and and Dendritic cells (by way of PAMPs and DAMPs) can initiate and mount an immune response, why antibodies need to be produced. Ok, antibodies opsonize the intruders. But then even without antibodies, the innate immune system...

This week, the US National Institutes of Health released an update on a trial in the Democratic Republic of the Congo comparing the effectiveness of two new antibody-based drugs (REGN-EB3 and mAb114) against existing treatments for Ebola (ZMapp and remdesivir). The trial was halted early...

I watched many videos and read bunch of answers about this, but I was having a hard time finding an answer to this one point: What is the exact moment an organism realizes that it is under an attack? I understand that there might be a few different types of ways a body can react too. So far...

Recently I came upon the description of medical tests for hormones like cortisole, or tyroid hormones like T3 and T4, which use polyclonal antibodies from hamsters, pigs, sheep or thelike. As far as I know, they are obtained by vacunating these animals and harvesting the antibodies from their...

Hello. Sorry in advance for my ignorance, but I am looking for a reaction that will yield a colorimetric signal when an antigen and an antibody meet. Similar to a one-step ELISA. My plan was to use HRP-conjugated BSA and anti-BSA. Will this work, and in how many steps? Any kits out there for...

Nice little paper about properly validating your reagents: http://www.ncbi.nlm.nih.gov/pubmed/22361696Why is it in academia absolutely no one validates their reagents like antibodies while in industry it is absolutely required? Rather than admitting their results are due to nonspecific...

i was told that only mammals have(can produce by their own) antibody... then how abt other animals like reptile,bird n fish?? without antibody,how can those animals protect themselves against diseases??

Hello everyone, There was a simple question given, where there was a bee sting on a guy and the question asked was what is the antibody involved. The answer is IgE. Now my question is when there is bee sting for the first time, why do we called it an allergic reaction. I mean for an allergy...

How are IGE antibodies related to an increase of allergies in the world?

I read that t-cells have receptors on their surface which bind to antigens. Are these receptors antibodies or are antibodies molecules which float around freely and mark antigens that they happen to bind to so that t-cells can kill them?
