Features & Benefits
Human Peroxidasin homolog (PXDN) ELISA Kit has high sensitivity and excellent specificity for detection of Human PXDN. No significant cross-reactivity or interference between Human PXDN and analogues was observed.
Background
Drosophila peroxidasin is an extracellular matrix-associated peroxidase. It is expressed exclusively in hemocytes derived from head mesoderm at a very early stage of differentiation. Peroxidasin exists as a homotrimer with a unique hybrid structure that combines an enzymatically functional peroxidase domain with motifs that are typically found in extracellular matrix-associated proteins.
It is a secreted protein that contains a secretory recognition sequence at its N terminus. Peroxidasin catalyzes hydrogen peroxide-driven radioiodination, oxidations, and the formation of dityrosine in vitro. It is also thought to function in extracellular matrix consolidation, phagocytosis, and defense.
This Peroxidasin homolog (PXDN) 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 Peroxidasin homolog (PXDN) 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.
