Human FABP9 (Fatty Acid Binding Protein 9, Testis) ELISA Kit (HUFI03425)

Assay Genie's Human FABP9 ELISA Kit targets the testis-enriched fatty acid carrier protein encoded by the FABP9 gene, also known as T-FABP or TLBP. This 15 kDa intracellular lipid-binding chaperone is expressed predominantly in late spermatocytes and round spermatids, where it shuttles long-chain fatty acids during spermiogenesis and supports the membrane remodelling that shapes the developing sperm head. Researchers in andrology, reproductive biology, and male infertility biomarker discovery apply this assay to quantify FABP9 concentrations in serum, heparin plasma, and EDTA plasma, using a 100 uL sample volume per well on a precoated microplate. Each kit contains a biotinylated detection antibody, streptavidin-HRP conjugate, calibrated protein standards, TMB substrate, and wash buffer. Unopened kits are shipped at ambient temperature; components should be stored at -20 degrees C upon receipt, and reconstituted standard aliquots remain stable through multiple freeze-thaw cycles. The microplate is for single use, and the supplied protocol runs experimental samples in duplicate alongside the standard curve.
