Scientific Background
The SLC7A7 gene encodes the light subunit of a cationic amino acid transporter. Together with the heavy chain, 4F2hc (SLC3A2), the SLC7A7 protein forms a functional heterodimeric transporter on the basolateral cell membrane of epithelial cells that transfers lysine, arginine, and ornithine from the cell to the extracellular space The SLC7A7 gene encodes a deduced 511-residue protein with a molecular mass of 56 kD that contains 12 transmembrane domains. The protein sequence shows 81% homology to the opossum protein. Northern blot analysis identified a 2.4-kb mRNA transcript expressed in kidney,.
Assay Principle
This assay employs a two-site sandwich ELISA to quantitate SLC7A7 in samples. An antibody specific for SLC7A7 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySLC7A7 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SLC7A7 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SLC7A7 bound in the initial step. The color development is stopped and the intensity of the color is measured.

Safety & Regulatory
Handle reagents in accordance with institutional biosafety guidelines. Refer to the Safety Data Sheet (SDS) for complete hazard and handling information. Contains components that may require special disposal procedures per local regulations.
This kit is validated for use with serum, plasma, cell culture supernatant, tissue homogenate. For unlisted matrices (e.g., tissue lysate, urine), perform a spike-and-recovery experiment to confirm assay performance before generating reportable data. Sample dilution in the kit's provided diluent is recommended to minimize matrix interference.
The minimum detectable concentration (sensitivity) of this kit is 0.114 ng/mL. Values below this threshold should be reported as below the limit of detection (<LOD) and should not be extrapolated from the standard curve.
The total assay time from sample addition to absorbance reading is approximately 3.5–5 hours, including all incubation, wash, and substrate steps. Hands-on time is typically 1–2 hours; most steps involve passive plate incubation. Plan the assay as a single uninterrupted session for best results.
Standard components of this Sandwich ELISA Kit typically include: pre-coated microplate (96-well strip format), lyophilized or liquid recombinant SLC7A7 standard, detection antibody, streptavidin-HRP conjugate, TMB substrate, stop solution, wash buffer concentrate, and sample/standard diluent. Refer to the kit insert or datasheet for the exact component list and storage requirements.
This kit uses colorimetric (TMB/HRP) detection and requires a standard microplate absorbance reader capable of measuring at 450 nm. A reference wavelength of 570 nm or 630 nm is recommended to reduce background. No specialized fluorescence or luminescence reader is needed. Ensure the instrument is calibrated and the plate is clean and free of condensation before reading.
