Summary Introduction
Introduction:
Serology is a method which is used to analyze the blood for the presence of a specific antibody and antigens. There is wide-range of serological tests available to recognize the antigens or antibodies in the blood. Using tagged or labelled antibody to identify an antigen is an altered form of serological testing method, for example, fluorescent antibody tests.

An MLS has completed an antibody panel using PEG. She cannot exclude anti-Fya, or anti-E. Anti-Kpª and anti-Ja cannot be excluded either but they are low incidence antigens and the MLS is not concerned with those at this time. What would be the next logical step to aid in antibody identification?
a. Run the panel again using ficin treated cells
b. Run the panel again using 22% albumin for enhancement
c. Pay special attention to the strength of the agglutination reactions
d. Run the panel again but increase the 37 degree incubation time to one hour
Which of the following components can be used in
an ELISA?
I. Polyclonal antibodies
II. Monoclonal antibodies
III. Protein A immobilized on agarose beads
Select one:
A. II and III only
B. I only

A technologist failed to notice that the centrifuge had not properly centrifuged the test tubes prepared for antibody identification. The time of centrifugation was 15 seconds instead of 30 seconds. What would be the potential error in the interpretation of this test? can please any one provide me ans?

- Antibodies can be divided into monoclonal and polyclonal. State the main difference between them. Which type of antibodies is more preferable in routine bioanalysis? Explain your answer.arrow_forwardSuppose you were instructed to make two antiserum solutions: The first is identical to what you used in the lab exercise. The other is a 10:6 dilution of the antiserum. After incubation with the antigen, the full-strength antiserum produces a precipitous ring, but the diluted antiserum does not. Explain these results. Is this due to poor specificity or sensitivity of the test?arrow_forwardIf you were using the ELISA to look for the presence of antibodies and the sample gave a negative result, does this mean that there were no antibodies present? Explain.arrow_forward
