Used in biomedical research to quantify levels of Human Kinase Anchor Protein 4 (AKAP4) in biological samples, this ELISA kit is particularly valuable in reproductive health studies. It enables researchers to investigate AKAP4's role in sperm maturation and motility, as the protein is predominantly expressed in testicular tissue and sperm flagella. The kit supports studies on male infertility by helping identify abnormal AKAP4 expression levels, which have been linked to impaired sperm function. Additionally, it is used in cancer research, as AKAP4 has shown potential as a tumor-associated antigen in certain cancers, such as cervical and lung cancer, aiding in the development of diagnostic markers and immunotherapeutic targets.
