Why IS it necessary to wear gloves during the electrophoresis procedure?

Wearing gloves during the electrophoresis procedure is essential to prevent contamination of samples and reagents, which can lead to inaccurate results. Gloves also protect the user from exposure to potentially hazardous chemicals and biological materials involved in the process. Additionally, handling samples with gloves minimizes the risk of introducing foreign substances from skin oils or dirt that could affect the electrophoretic separation.
