Question

What conditions, in terms of time and temperature, are necessary to inactivate native (endogenous) complement in the field of immunology or laboratory techniques?

A) Rapid freezing at -80°C for a short duration
B) Prolonged exposure to high temperatures (above 70°C)
C) Quick heating to 37°C for a brief period
D) Room temperature storage for an extended period

Answer 1

To inactivate native complement in immunology or laboratory techniques, prolonged exposure to high temperatures above 70°C is necessary.

Step-by-step explanation:

To inactivate native (endogenous) complement in the field of immunology or laboratory techniques, prolonged exposure to high temperatures (above 70°C) is typically necessary. Heating the serum at high temperatures destroys all of the complement. Rapid freezing at -80°C for a short duration or quick heating to 37°C for a brief period may not be sufficient to inactivate the complement.
