• Alpha‑Tec’s MarScreen® is a quick and simple assay for testing fresh semen samples. Using a combination of antiserum to human IgA, IgG, and bead-conjugated IgG antibodies, MarScreen® can test for the presence or absence of antisperm antibodies (ASA) on the surface of sperm within minutes, making it an ideal tool for screening for immune-mediated male infertility or unexplained infertility in couples. MarScreen® can be used with direct and indirect testing methods. For direct testing, fresh ejaculate is used. Indirect testing requires a patient blood sample or serum. Product packaging may differ from image.

  • Alpha‑Tec Serum Control Kits are used to establish controls during antisperm antibody assays. The Serum Control Kit’s positive serum contains IgA and IgG antibodies, whereas its negative serum contains no detectable antibodies against sperm. Using a positive control during direct sperm antibody testing can overcome the impracticality of using antibody-positive sperm specimens as positive controls. Using a negative control during testing is also recommended. Both Sperm Antibody Positive A/G Serum and Sperm Antibody Negative Serum have been tested and found to be negative for HIV antibodies and hepatitis B surface antigens, however negative results do not guarantee absence of these viruses. Product packaging may differ from image.
