Serum Used as the Sample for Electrophoretic Analysis in Clinical

question 12

Multiple Choice

Serum used as the sample for electrophoretic analysis in clinical laboratories contains many groups of macromolecules.Examples include amino acids, serum proteins, lipoproteins, glycoproteins, and others.Suppose an analyst is interested in performing serum protein electrophoresis.How does the analyst prevent other groups of macromolecules from interfering with the analysis of serum proteins?

• A)by selecting a medium that will only allow the electrophoretic migration of serum proteins
• B)by selecting an electrophoresis voltage that will only cause migration of serum proteins
• C)by selecting an electrophoresis time that will allow all other macromolecules to migrate completely off the medium and leave only serum proteins
• D)by selecting a stain that will only visualize the desired serum proteins

Fifth Element

A reference to the component in various frameworks that is considered essential but is often intangible or abstract, such as spirit or culture in organizational contexts.

Quasi-experimental Designs

Research methodologies that resemble experimental strategies but lack random assignment of participants to groups.

Non-experimental Designs

Non-experimental designs refer to research methodologies that do not involve the manipulation of variables or random assignment of participants, often used to observe and analyze phenomena as they naturally occur.

Experimental Designs

Research methods used to test hypotheses and establish cause-effect relationships by manipulating variables and controlling conditions.
