Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of human AKAP4 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

(From Uniprot)
Major structural component of sperm fibrous sheath. Plays a role in sperm motility.
Gene References into Functions
  1. High AKAP4 expression is associated with reduced sperm motility. PMID: 29581387
  2. A significant association was found between AKAP4 gene expression and metastasis (P-value: 0.045), expression of the CTAG1B (NY-ESO-1) gene was not observed in our cases. PMID: 29480665
  3. the physiological role of the negative crosstalk between the cAMP/PKA/AKAP4 and the PKC/ERK1/2 pathways is to regulate capacitation and acrosome reaction. PMID: 27901058
  4. AKAP4 role in the proliferation and metastasis of thyroid cancer.AKAP4 is highly expressed in thyroid cancer. PMID: 27983916
  5. AKAP4 appears to be a novel Colorectal cancer-associated antigen with a potential for developing as a new clinical therapeutic target PMID: 26590805
  6. AKAP4 is a highly accurate biomarker for the detection of early stage lung cancer. PMID: 26160834
  7. SP17/AKAP4/PTTG1 are expressed in both human NSCLC cell lines and primary tumors and can elicit an immunogenic response in lung cancer patients. PMID: 25739119
  8. The putative role of AKAP4 in early tumorigenesis is implicated as a biomarker and immunotherapeutic target for cervical cancer. PMID: 23478221
  9. Ablation of AKAP4 protein caused significant inhibition in cellular proliferation, colony-forming ability, migration and invasion ability of tumor cells. PMID: 23764900
  10. data suggests that AKAP4 may be used as serum based diagnostic test for an early detection and diagnosis of breast cancer and may be a potential target for immunotherapeutic use PMID: 23451156
  11. We demonstrate the aberrant expression of AKAP-4 in prostate cancer, which will potentially be developed as a biomarker in prostate cancer. PMID: 21520158
  12. AKAP4 is a novel target for protein S-nitrosylation in spermatozoa. PMID: 17683036
  13. Role of AKAP4 in sperm motility is unclear, vut absent or weak AKAP4-labelling is associated with absent or weak sperm. motility. PMID: 17712481
