Difficulty: Easy
Correct Answer: All of these
Explanation:
Introduction / Context:Human monoclonal antibodies can be produced through several laboratory strategies that avoid the immunogenicity issues of mouse antibodies. This question surveys recognized approaches used historically and in many teaching resources for generating fully human monoclonals.
Given Data / Assumptions:
Concept / Approach:EBV-based transformation yields lymphoblastoid lines; fusion with plasmacytoma creates stable hybridomas. Blending methods captures advantages of both: selective expansion of the right B cells and long-term secretion stability. Although modern platforms include transgenic mice and phage display, the options listed reflect classic human cell-derived strategies taught in immunotechnology.
Step-by-Step Solution:
Recognize each listed approach as a valid route to human mAbs.Note synergy when combining EBV transformation with fusion techniques.Choose the inclusive option encompassing all methods.Verification / Alternative check:Protocols and reviews in immunotechnology literature document these methods as workable paths to human monoclonals.
Why Other Options Are Wrong:
Single-method answers are incomplete; multiple approaches are valid.None of these is false given the historical context and established techniques.Common Pitfalls:Assuming only one “best” method exists; in practice, labs adopt different pipelines depending on resources and goals.
Final Answer:All of these.
