Sampling and Preparation of Mouse and Rat Serum

Area of Science:

• Immunology
• Animal Research

Background:

• Specific antibodies are crucial indicators of immune response after immunization.
• Serum is preferred over plasma for many clinical assays due to fewer interfering proteins.

Purpose of the Study:

• To describe methods for obtaining blood samples and preparing serum for antibody analysis.
• To outline safe blood collection volumes and frequencies in animal models.

Main Methods:

• Serum collection from clotted blood, excluding fibrinogen and clotting factors.
• Detailed procedures for blood sample acquisition and serum preparation.
• Guidelines for determining maximum blood withdrawal volumes and intervals.

Main Results:

• Serum provides a cleaner sample matrix compared to plasma for immunological assays.
• Established protocols ensure reliable serum preparation for antibody detection.
• Safe blood collection limits (7%-9% of blood volume or 1% body weight every 2-4 weeks) are defined.

Conclusions:

• Standardized methods for serum collection are vital for accurate antibody assessment.
• Adherence to safe blood collection practices is essential for animal welfare and experimental validity.
