RESUMO
Objective To establish a rapid method for the detection of SMCY antigen. Methods To Use the technology of colloidal gold immunochromatography with double antibody sandwich assay, the gold labeled pad was coated with colloidal gold labeled SMCY rabbit polyclonal antibody, colloidal gold strip was made for detection of serum, which include 12 serum samples of pig, cattle, dog, chicken and mice and 50 serum samples of human. Results The colloidal gold test strips showed obvious specificity in human and common animal sera and could distinguish between male and female sera. Conclusion This method can be used to identify the serum of women and men, and has certain species specificity, which provides a direction for forensic science to rapidly identify gender of human samples.
