Good evening! As a Grade 12 student with a strong interest in immunology and biotechnology, I’m currently following Dr. Brianne Barker's Immunology Fall 2024 course on RUclips. I find your channel particularly valuable as I plan to pursue biotechnology and immunology in my studies, with the possibility of aiming for a PhD. Could you recommend any key books on immunology and biotechnology that would be beneficial at my level? ❤
Good evening. As a Grade 12 student, you may find some concepts challenging at first, but I encourage you to begin your journey with the following essential texts: for immunology, I highly recommend the "Kuby Immunology, 7th edition." For biotechnology, "The Cell: A Molecular Approach" by Bruce Alberts is an excellent foundation.
@@learnbiotechnologyandmicrobiol Thank you so much! I'll check out these books in our school library. I've been interested in immunology for the past five years and have been gradually gathering information and studying during that time to support my long-term goals. Thank you once again <3.

Es posible entender la diferencia entre los microarreglos de proteinas
Yes there are some differences between protein and DNA microarrays and I will soon make a video on DNA microarray. The basic difference is DNA microarray is an arrangement of DNA spots (in picomole) attached to a solid surface for the detection of DNA (gene) while in a protein microarray, collection of purified proteins, antibodies, affibodies etc are attached on a solid surface.

Nice video. Quick question: Did they centrifuge to be able to kill all the cells? If so, why did they homogenize again before adding the enzyme? Also, what did they use to homogenize the cells?
Thank you for the nice comment. Centrifugation served two main purposes in their experiments: 1. Initially, as the bacterial culture was grown in a liquid medium, they aimed to isolate the bacterial cells from the media. Centrifugation was employed to separate the denser bacterial cells, which formed a pellet, from the lighter media found in the supernatant. 2. After cell lysis, centrifugation played a crucial role in segregating cell debris and unbroken cells from the cellular components released during the lysis process. The answer to your second question is: After employing mechanical and enzymatic treatments, a homogenizer was used to further break down the cells. I hope this answers your questions. Feel free to contact if there is still any query
