The video tutorial discusses Hastings, a protein derivative from milk, and its role in stabilizing antibodies in assays. It compares lab-grade materials with basic experiments using milk powder. The tutorial explains how proteins help reduce background noise in assays, making it easier to count antibodies. It also touches on measuring antibody production, which varies among individuals based on their serum.

In what ways can background noise in an assay be reduced?

How does individual variation affect antibody production in assays?
