Features & Benefits
Human Zinc transporter ZIP4 (SLC39A4) ELISA Kit has high sensitivity and excellent specificity for detection of Human SLC39A4. No significant cross-reactivity or interference between Human SLC39A4 and analogues was observed.
Background
SLC39A4 gene as a candidate intestinal zinc-specific transporter within the susceptibility locus for the zinc-deficiency type of acrodermatitis enteropathica (AEZ) on 8q24.3. The gene is expressed as an mRNA of 2.5 kb in only a few tissues, i.e., kidney, colon, duodenum and jejunum. The duodenum and jejunum are crucial sites of zinc absorption. These transcripts encode proteins of 647 and 622 amino acids sharing the same C-terminal 583 residues. Computational analysis predicted that the larger protein has a cytoplasmic membrane location and a secondary structure characteristic of a ZIP protein, consisting of 8 transmembrane domains organized in 2 blocks of 3 and 5, respectively. These 2 blocks are separated by a variable intracytoplasmic metal-binding site.
This Zinc transporter ZIP4 (SLC39A4) ELISA kit is validated for use with Cell culture supernatants, Serum, Plasma, Other biological fluids. Samples should be collected, processed, and stored correctly to preserve analyte integrity — avoid repeated freeze-thaw cycles and centrifuge to remove particulates before use. Dilute samples exceeding the kit's detection range using the supplied assay diluent. Hemolytic, icteric, or lipemic samples may affect assay performance and should be tested with caution.
This is a sandwich ELISA kit employing an HRP (horseradish peroxidase)-conjugated secondary antibody paired with a TMB (3,3′,5,5′-tetramethylbenzidine) colorimetric substrate. In the sandwich format, the target analyte Zinc transporter ZIP4 (SLC39A4) captured on the microplate surface is detected by the conjugated antibody, generating a colorimetric signal proportional to analyte concentration. The reaction is stopped and absorbance measured at 450 nm on a standard microplate reader.
The complete protocol, from sample addition to final plate reading, requires approximately 3–5 hours. This includes two incubation periods (analyte binding and detection antibody steps), intermediate wash cycles to remove unbound material, 15–30 minutes of TMB substrate development, and final stop-solution addition before absorbance reading. Exact timing will vary with experience level and the number of samples processed in parallel.
Required equipment: (1) a microplate spectrophotometer capable of reading absorbance at 450 nm (reference wavelength 540–570 nm recommended for background correction); (2) precision single-channel or multichannel pipettes; (3) a plate washer or multichannel aspirator; (4) a microcentrifuge for sample clarification; and (5) a 37°C incubator or stable room-temperature environment. No fluorescence or luminescence reader is required — standard colorimetric plate readers are fully compatible with this kit.
This ELISA kit is formally validated for Human. Cross-reactivity with species not listed in the specification has not been independently characterized. Variability in protein sequence homology across species means that performance in unlisted species cannot be guaranteed without additional validation. For cross-species detection requirements or non-standard sample matrices, please contact BioHippo support or refer to the manufacturer's technical team for guidance.
