A primary antibody can be very useful for the detection of biomarkers for diseases such as cancer, diabetes, Parkinson’s and Alzheimer’s disease and they are used for the study of absorption, distribution, metabolism, and excretion (ADME) and multi-drug resistance (MDR) of therapeutic agents. Visa mer Primary and secondary antibodies are two groups of antibodies that are classified based on whether they bind to antigens or proteins directly or target another (primary) antibody that, in turn, is bound to an antigen or protein. Visa mer Secondary antibodies provide signal detection and amplification along with extending the utility of an antibody through conjugation to … Visa mer WebbSince several secondary antibodies can bind different epitopes of the primary antibody, indirect method ensures an amplified signal and a higher sensitivity. In addition, it also allows higher flexibility as just few types of secondary antibodies can be used to detect a wide range of primary antibodies against the different antigens. shanna hatfield book list
