- Which of the following primary sequence of an antibody has the greatest diversity? Question 13 options: All regions are similarly conserved. Fab region Complementarity-determining region (CDR) Fc region receptor binding domain (RBD)choose correct option from given option.Question 10 of 14 Which of the following are true about MHC class I and MHC class II peptide loading? Select all that apply. MHC class I peptide loading occurs in four steps. Peptide loading of class I molecules generated from intracellular proteins occurs in the endoplasmic reticulum. ⒸMHC class II molecules are loaded before they are part of a vesicle capable of fusing with a phagolysosome. Peptide loading of class II molecules occurs later in the secretory pathway than that of MHC class I molecules.

- Three (3) true positives (antigen is present and patient's sera reacted) and three (3) true negatives (antigen is not present and patient's sera did not react): Question 3 options: Is a tool that can be used to increase the probability that any alloantibodies identified is/are correct Is an AABB requirement in order to prove each alloantibody specificity Proves that the antibody procedure was performed correctly Gives a P value of 95%Which statement about antibodies is INCORRECT? Question 16 options: Antibodies can be both soluble and membrane-bound. Antibodies bind to antigens via induced fit. Antibodies never release antigens once they are bound together. More than 100 million different antibodies can be produced in humans. Antibodies typically bind to antigens more strongly than enzymes bind to substrates.I understand what autoantibodies are, but are ANAs the same thing as autoantibodies, or is there a difference between them. anti-nuclear antibodies (ANAs)
