Features & Benefits
Human Protein S100-A7A (S100A7A) ELISA Kit has high sensitivity and excellent specificity for detection of Human S100A7A. No significant cross-reactivity or interference between Human S100A7A and analogues was observed.
Background
The human calcium-binding protein (hS100A15) was first identified in inflamed hyperplastic psoriatic skin, where the S100A15 gene is transcribed into two mRNA splice variants, hS100A15-S and hS100A15-L. In cultured keratinocytes, IL-1beta and Th1 cytokines significantly induced hS100A15-L compared with hS100A15-S. In contrast, Th2-derived cytokines had no influence on the expression of either hS100A15 splice variant. Differentiation of human keratinocytes induced by 1.2 mm calcium resulted in the upregulation of both hS100A15 mRNA isoforms. Overexpression of hS100A15 in chronic inflammatory skin diseases and regulation by inflammatory cytokines and calcium suggest that hS100A15 is involved in Th1-associated epithelial responses and epidermal maturation in normal and diseased human skin.
This Protein S100-A7A (S100A7A) 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 Protein S100-A7A (S100A7A) 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.
