Extracellular signals are transduced into cells through mitogen-activated protein kinases. The structural organization of these kinases into specific signaling domains is facilitated by scaffolding proteins involved in closely tethering different kinases so that successive phosphorylation events can occur.Sperm Associated Antigen 9 is a scaffolding protein that brings together mitogen-activated protein kinases and their transcription factor targets for the activation of specific signaling pathways. This gene which is abundantly expressed in testicular haploid germ cells encodes a protein that is recognized by sperm-agglutinating antibodies and implicated in infertility.Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Human Sperm associated antigen 9 antibody (SPAG9-Ab) ELISA Kit has been pre-coated with an antibody specific to SPAG9-Ab. Standards or samples are then added to the appropriate microtiter plate wells with a Horseradish Peroxidase (HRP)-conjugated SPAG9-Ab and incubated. The competitive inhibition reaction is launched between with HRP labeled SPAG9-Ab and unlabeled SPAG9-Ab with the antibody. A substrate solution is added to the wells and the color develops in opposite to the amount of SPAG9-Ab in the sample. The color development is stopped and the intensity of the color is measured.
