Antibodies are crucial for the immune system and proper storage is important for research and development. Most methods emphasize keeping antibodies cold, with recommended temperatures ranging from 4°C to -80°C. Aliquoting and avoiding freeze-thaw cycles can also help maintain antibody integrity.
The study of antibodies can be an important area of biomedical research and development. In general, this is due to the valuable role that antibodies could play in helping the immune system function properly. Storing antibodies in laboratories can be a significant part of the research and development process, as proper storage methods can help ensure that antibodies remain intact.
Antibodies are types of proteins commonly found in blood. They are generally considered a crucial part of the immune system, which uses them to identify and fight bacteria and viruses. All antibodies normally have the same basic structure, but an area at the tip of the protein can vary widely. The differences in antibodies allow them to perform different functions for the immune system, such as assisting in the deactivation of any number of different types of bacteria and viruses.
There is no standard method for storing antibodies. This is generally due to the wide variety of antibodies that exist, combined with a lack of consensus in the scientific community on the best storage methods. However, since antibodies are proteins, most storage methods emphasize that antibodies should be kept cold. This usually means the antibodies need to be refrigerated, stored on ice, or frozen.
Many experts recommend storing antibodies at a temperature of 39 degrees Fahrenheit (4 degrees Celsius) at the beginning of the storage process. Approaches may differ on how long this temperature should be maintained. Some scientists believe this temperature should only be maintained for up to two weeks, after which the antibody should be properly frozen. Thereafter, a temperature of -2 degrees Fahrenheit (-20 degrees Celsius) is usually recommended, although some scientists will store antibodies at temperatures as low as -112 degrees Fahrenheit (-80 degrees Celsius).
The location of the antibody within the freezer is also an important difference in antibody storage methods. To avoid drastic temperature changes, some methods emphasize placing the antibody in the back of the freezer instead of the front. This is generally intended to reduce the susceptibility of the antibody to temperature fluctuations that can occur when the freezer door is continuously opened and closed.
Aliquoting is also a possible method of storing antibodies. The size of an aliquot can vary, however quantities are generally between 0.507 ounces and 0.675 ounces (15 to 20 milliliters). Aliquots can help minimize any damage to the antibody from freezing or thawing. It could also reduce the chances of any contamination that may occur in the process.
The avoidance of freeze-thaw cycles is usually emphasized in many antibody storage methods. This is because the temperature change can damage the antibody. Freezing and thawing can usually occur once in the storage process, but others may denature the antibody which, for example, may prevent the antibody from binding. Consequently, frost-free freezers are usually not recommended for storing antibodies, as these refrigeration devices can automatically switch between freezing and thawing.
