The invention provides a preparation method for an anti-hepatitis B surface antigen antibody based on green fluorescent protein luminescence domain labeling, comprising: synthesizing a fusion gene GFP-F-Domain-anti-HBsAg as a first DNA sequence; performing amplification with the first DNA sequence as a template to obtain a second DNA sequence; connecting the second DNA sequence to an expression vector pET22b, inducing expression, and then performing disruption and purification to obtain the anti-hepatitis B surface antigen antibody.
