Features & Benefits
Human Formylmethionine (fMET) ELISA Kit has high sensitivity and excellent specificity for detection of Human fMET. No significant cross-reactivity or interference between Human fMET and analogues was observed.
Background
fMet-Leu-Phe receptor is a protein encoded by the FPR1 gene.Ozcelik et al. mapped the FPR1 gene to human chromosome 19 by Southern analysis of rodent/human somatic cell hybrids and use of a cDNA probe. An FPR-like gene was also identified on chromosome 19 . An FPR-like gene that mapped to chromosome 2 was found in fact to represent an interleukin 8 receptor. Bao et al. mapped the gene encoding the receptor for the chemotactic ligand FMLP to chromosome 19, using a panel of somatic cell hybrids. They identified 2 structural homologs of FPR that similarly mapped to chromosome 19. The structural homologs did not recognize the ligand FMLP, but were thought to represent chemotactic receptors. Bao et al. referred to them as orphan receptors and symbolized the genes FPRH1 and FPRH2.
This Formylmethionine (fMET) 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 Formylmethionine (fMET) 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.
