Features & Benefits
Human PRELI domain-containing protein 1, mitochondrial (PRELID1) ELISA Kit has high sensitivity and excellent specificity for detection of Human PRELID1. No significant cross-reactivity or interference between Human PRELID1 and analogues was observed.
Background
The predicted 219-amino acid human protein is 85% identical to the avian protein. PX19 contains 2 alpha helices with amphipathic domains in opposite orientation, and the LEA motifs (A/TAEKAK) are clustered within this region.
Northern blot analysis detected 1.0- and 1.2-kb transcripts predominantly in fetal liver, with much lower levels in other fetal tissues. Expression was significantly reduced in adult liver, but was higher in other adult organs. Expression was low in bone marrow and thymus, but high in adult spleen, lymph node, and peripheral blood leukocytes. Further analysis of B-cell lines indicated that expression was higher in mature B cells, predominantly from germinal centers, and absent in progenitor and precursor B-cell lines.
This PRELI domain-containing protein 1, mitochondrial (PRELID1) 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 PRELI domain-containing protein 1, mitochondrial (PRELID1) 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.
