Please answer the following questions: Western-blotting: principles and application. Steps involved in western-blotting. Pay attention to following steps: sample treatment (why proteinase inhibitor is added), protein quantification (Bradford method); SDS electrophoresis (separation according to MW). Purpose of blocking? (to prevent non specific antibody binding to the membrane) What are primary antibody and secondary antibody? How to detect antibody-antigen complex? Principles and application of Elisa (disease diagnosis). Steps involved in Elisa. Which enzyme is usually linked? And what is the substrate...

1. Western blotting: After western blotting process, the antibody detected too many non-specific bands, discuss possible reasons and how to improve the specificity. 2.If there was not any band, discuss possible reasons and how to troubleshoot? 3. If cultured cells were overgrown (1:2 seeding ratio), how to perform subculture experiment differently? 4. Determine the confluence of each of seeding ratio by estimation (1:10 and 1:20 ratio) 5. Procedure in cell subculture?

2) A blotting method known as Western blotting can be used to detect proteins that are translated from a particular mRNA This techniques first separates proteins by size using electrophoresis then detects specific proteins through staining (antibody directed). Key is that you can visualize only the protein of interest on the gel. Suppose a researcher was interested in the effects of mutations on the expression of a gene that encodes protein X This protein is expressed in the skin and...

100 1. How western blot does works and explain some of its possible application? 2. While using the sample buffer (Leammli buffer), there was SDS (detergent). Why was the SDS necessary for running the gel? 3. Why was it necessary for the transfer to the nitrocellulose membrane? 4. The first stage of western blotting involves separating proteins using gel electrophoresis. On what basis does this technique separate proteins? 5. How can you test the efficiency of transfer of the protein...
