Fluorescent antibody sample

WebImmunofluorescence is a technique for fluorescently labeling a specific biological target within a sample using an antibody. An antibody is a Y-shaped high–molecular weight glycoprotein, also called an immunoglobulin, that binds specifically (but noncovalently) to another molecule (often called the antigen or epitope). Webprimary antibody. Since antibody’s Fc domain is constant within the same animal class, only one type of secondary antibody is required to bind to many types of primary antibodies. This reduces the cost by labeling only one type of secondary antibody, rather than labeling various types of primary antibodies. Figure 3. Structure of IgG Protein.
