Explain why the antibodies allow scientists to target and identify specific disease agents. The antibodies are specific to the antigen they destroy. 2. Why is the secondary antibody used in the ELISA test conjugated with an enzyme? What happens when this enzyme meets up with its substrate? The enzyme catalyzes the oxidation of the substrate and turns the solution blue. 3. Disease samples from two patients are collected and subjected to serial dilutions before running an ELISA.What does it mean if a disease can be detected in samples from one person at a dilution of 1/5 and in another patient at a dilution of 1/100?

Discuss the limitations of using the antigen concentration to deduce the path of the infection. Be sure to refer to the workings of the human immune system. Overusing the antigen concentration can shut down your immune system and make your current state worse because of the virus. Your immune system may reject the antigen concentration and that won’t be good at all! 8. Using the information about how you completed this ELISA experiment, outline a procedure for testing for antibodies in the blood.Provide blood samples into separate wells. Inject a protein base into the wells. Add a primary antibody and provide a wash. Add the secondary antibody, then wash. Finally input an enzyme and extract observations whether it oxidizes. If it does, then the sample is positive for that antibody, linked to a specific disease. 9. Explain why in the sudden outbreaks, it may be better to test for disease antigens rather than for antibodies. Antigens are specific markers that initiate the antibodies. Therefore, antigens will have a higher initiative for marking the disease.

Nora And Hedda Essays - Ibsen Family, Nora, Hedda Gabler, Hedda Nora And Hedda Nora and Heddas Struggle for Independence In Isbens two plays, A Dolls House and Hedda Gabler, one character of each play breaks the stereotype or mold that is put on them.

She tries to help her husband and, according to the author, saves his life. Torvald is unaware of her sacrifice and is ashamed of Noras deceitful behavior. She is finally sick of being called a little skylark and a spendthrift and decides to leave Torvald, which is unheard during that time. The play ends with Nora slamming the door and Torvald mumbling to himself. Audiences react so violently to this ending because it shows a woman taking charge of her life and breaking the mold that stereotypes her. Hedda takes a different approach to changing the circumstances that stereotypes place her in. Being a woman, Hedda is seen as meek and mild by the men in Hedda Gabler. Her dream is to control and eventually ruin a human destiny, which means she must gain the trust of, or seduce, a human being. Her character of choice, and old flame, is Lvborg. Hedda doesnt escape her problems and run for cover like Nora did. Instead, Hedda takes her problems head on in hopes of changing them for her benefit. Her sarcastic tone and evil behavior make a dangerous combination. The reader experiences this mix when Hedda convinces Lvborg to kill himself. Eventually this head-on approach was too much for her and she takes her own life rather than be suppressed by a male. Nora and Hedda have two totally different personalities and character traits.
