Shortly after the recovery from COVID 19, the plasma of the convalescent has significant quantities of anti - SARS CoV - 2 antibodies. This plasma was suggested to be used as therapy for other COVID - 19 patients by transfusing the plasma from the recovered individuals (donor) to the other COVID 19 patients (recipient). Do you think the identification of the ABO group of the donor and recipient is important and why

Shortly after the recovery from COVID-19, the plasma of the convalescent has significant quantities of anti-SARS-CoV-2 antibodies. This plasma was suggested to be used as therapy for other COVID-19 patients by transfusing the plasma from the recovered individuals (donor) to the other COVID-19 patients (recipient). Do you think the identification of the ABO group of the donor and recipient is important and why? O a. No, this has nothing to do with blood grouping. It is only related to the virus and the antibodies against it. O b. Yes, but I really have no idea why. O c. No, not important because the antigens A, B or AB exist on the surface of red blood cells but not in the plasma and when they transfer, they do not transfer cells (only plasma) O d. Yes, because the donor plasma might contain anti-A or Anti-B or both which might induce an immune response if the recipient has A or B or AB group. Clear my choice

If antibody responses are not elicited by a Covid-19 vaccine, are there other types of immune response that could provide protection from the SARS-Co-V2 virus following vaccination? Explain why or why not.
COVID-19 is caused by infection with a novel corona virus, SARS-CoV-2. Testing someone for active infection involves examining samples taken from the nasal mucosa for fragments of the virus. Another type of testing involves examining blood for the presence of antibodies that can bind to SARS-CoV-2. Use what you've learned about the immune system. What are the suggested reasons why someone would possess antibodies to SARS-CoV-2.
Addition of immunoglobulin G (IgG) specific for hemoglobin to a solution of hemoglobin results in the formation of a red precipitate. In contrast, addition of the Fab fragments from this antibody to hemoglobin results in no such precipitate. What could explain this difference in results? Treatment with papain produces Fab fragments with different antigen specificity than the original IgG molecule. IgG can simultaneously bind two different antigens, whereas an Fab fragment can only bind one antigen at a time. The Fab fragments preferentially bind to other Fab fragments rather than to hemoglobin. The hemoglobin molecule antibody-binding sites can bind IgG molecules, but cannot bind Fab fragments.
A 6 month old pediatric patient is B-negative. She has received a unit of platelet pheresis that appeared to be bloody. the estimated blood volume in the unit of platelets is estimated to be 5 mLs. Please calculate the dose of RhLg (standard) to be injected to this patient to prevent stimulation of alloanti-D (HINT: It's estimated that 5mL of red blood cells are in the unit of platelets, so think of the 5 mL volume of red blood cells as being "packed cells" rather than whole blood) Need answer ASAP and in short .
Can S-layer proteins be detected by immunolabelling when a capsule is present? How do you know? I need help finding the answer in the article and explain in short answer link to article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC106848/
1) A drug called Bamlanivimab can be used to treat infections with SARS-CoV-2 (Covid-19).This drug was developed by isolating antibodies from the serum of a patient who recovered from Covid-19.What do you think is on the stationary phase in a column used to isolate antibodies to SARS-CoV-2? How are the antibodies eluted off the column to isolate them for drug development?
In terms of antigens and antibodies, explain why O- is considered a universal donor and why AB+ is considered a universal recipient. Even so, why can’t whole blood O- be donated to a person of type AB+ blood?
Serum from individuals with high levels of antibody to SARS-CoV2 has been used to treat patients with severe COVID-19. What is ONE way (there are several) that passive immunization with the antibody to the virus could help these patients? HINT: think about what opsonization with antibody could do for the innate immune response.
You just received the properly labeled blood bank specimen on patient Aran Stark. You decide to collect some background information about her known historical antibodies before beginning the work-up knowing that she has a history of anti-E, anti-K, anti-Jk^a, anti-Fy^a, anti-M and anti-Le^a. Which of these antibodies have been known to cause hemolytic transfusion reaction?
Given your current understanding of what we have learned about the SARS-CoV-2 virus and the disease it causes, CoVID-19, which of the following recommended practices make sense, based on the scientific knowledge you now have? Explain your answer for each: Remaining 6 feet away from other people, wearing non-medical masks, screening people for fevers before they can board planes or enter schools, not gathering in large groups.
