Why is storing the spleens on Dulbecco’s phosphate-buffered saline solution containing 3% fetal bovine serum and 1% antibiotic-antimycotic on ice done in splenocyte preparation?

Why does antibody titer rise after infection? Is ahigh antibody titer indicative of an ongoing infection?Explain

You are presented with the following clinical scenario: "A 12 month old male child presents with recurrent bacterial infections. Flow cytometry shows a complete lack of B- lymphocytes." Using your knowledge of immunology and flow cytometry, identify which dot plots represent the healthy control and patient samples in each scenario and come up with a clinical diagnosis. Note that you may need to use additional background sources to fully understand what is going on at the cellular level for each diagnosis. What is the clinical diagnosis O HIV/AIDS O COVID-19 O LAD type 1 U E CD4-FITC CD8-PE CD45-PE CD8-PE 70% 13% 52% 10% 82% 5% 27% 5% CD8-PE CD4-FITC CD20-FITC CD4-FITC 17% 38% 13% 68% Agammaglobulinaemia CD45-PE CD4-FITC CD45-PE CD45-PE 35% 3% 62% 8% 93% 22% CD15-FITC CD8-PE CD20-FITC CD15-FITC Select the flow cytometry dot plot that corresponds to the healthy control sample Select the flow cytometry dot plot that corresponds to the patient sample 62% 30% 0% 77%

Briefly Explain this statement "Immunomodulator Agents "-Please explain at your own words.

(Please answer all parts, thank you!) 1) Mature red blood cells contain hemoglobin for transporting oxygen but contain little else. They lack a nucleus and most organelles. Are red blood cells more or less likely to be infected by a virus? a) More likely  b) Less likely    2) How does SARS-COV-2 genetic material get replicated? a) Host cell DNA polymerase b) Host cell RNA polymerase c) RNA polymerase encoded for by viral genome and built in the host cell  d) RNA polymerase encoded for by viral genome and originated from the virus    3) How does SARS-COV-2 proteins get built? a) The host cell's ribosome b) Ribosome encoded for by viral genome and built in host cell

A pathogenesis function f(t)t(t-21)(t + 1) is used to model the development of the disease, where t is measured in days and f(t) represents the number of infected cells per mL of plasma. What is the peak infection time for this virus? (Round your answer to one decimal place.) t= Need Help? X days Read It

A Medical Technology staff in blood bank laboratory proceeds with weak D/Du typing in one of her blood donor who happened to be RH negative for anti-D typing.  She performed indirect antihuman globulin test (IAT) and her results revealed the presence of agglutination.Question 1: How will the MT staff reports the RH type of the donor? Support answer (with explanation). Question 2: Can a Du positive patient be classified as RH negative? Support answer (with explanation).
