What hormone indicates pregnancy in urine tests?
What hormone indicates pregnancy in urine tests?
Human chorionic gonadotrophin (hCG) indicates pregnancy.
What do mobile antibodies detect in pregnancy tests?
What do mobile antibodies detect in pregnancy tests?
They detect the hormone hCG in urine or blood.
What do stationary antibodies do in pregnancy tests?
What do stationary antibodies do in pregnancy tests?
They bind to hCG complexes, forming a blue line.
What triggers the blue line in a pregnancy test?
What triggers the blue line in a pregnancy test?
Bound hCG/antibody complexes with blue beads create it.
Why are monoclonal antibodies used in hormone testing?
Why are monoclonal antibodies used in hormone testing?
They specifically bind to target hormones like hCG.
What are two uses of monoclonal antibodies in medicine?
What are two uses of monoclonal antibodies in medicine?
They can treat diseases and deliver drugs to targeted cells.
What is one research application of monoclonal antibodies?
What is one research application of monoclonal antibodies?
They can be used to study disease mechanisms in labs.
What is the role of monoclonal antibodies in cancer therapy?
What is the role of monoclonal antibodies in cancer therapy?
They target cancer cells for destruction or mark them.
What must be present for a positive pregnancy test result?
What must be present for a positive pregnancy test result?
hCG must be present in the urine for a positive result.
What role do blue beads serve in pregnancy testing?
What role do blue beads serve in pregnancy testing?
They help visualize the binding of antibodies to hCG.
