Antibody based diagnosis refers to diagnostic methods that utilize antibodies to detect the presence of specific pathogens (such as viruses, bacteria, or fungi) or abnormal biomarkers (such as proteins or other molecules) in a patient’s biological samples (e.g., blood, urine, saliva, or tissue). These diagnostic techniques utilize the specific binding capabilities of antibodies to their … Read more
ELISA (Enzyme-Linked Immunosorbent Assay) is a powerful laboratory technique used to detect and quantify proteins, antibodies, and antigens. It is widely used for diagnosing infectious diseases caused by bacteria, viruses, and parasites. The method is favored for its sensitivity, specificity, and ability to process multiple samples simultaneously. Principle of ELISA ELISA involves the following basic … Read more
T cell receptors (TCRs) are critical components of the adaptive immune system. They are responsible for recognizing antigens, which are specific molecules or fragments from pathogens (like viruses and bacteria) that trigger an immune response. Understanding TCRs is essential for grasping how T cells function in immune surveillance and response. Imagine a battleground where microscopic … Read more
