Features & Benefits
Human Thioredoxin-related transmembrane protein 1 (TMX1) ELISA Kit has high sensitivity and excellent specificity for detection of Human TMX1. No significant cross-reactivity or interference between Human TMX1 and analogues was observed.
Background
TXNDC1 is a thioredoxin (TXN)-related protein with disulfide reductase activity. The deduced 280-amino acid protein has a predicted molecular mass of 31.8 kD and contains an N-terminal signal sequence, a TRX-like domain with an active site sequence CPAC, and a transmembrane domain.
Northern blot analysis detected a 2.5-kb transcript in all tissues examined, with highest expression in kidney, liver, placenta, and lung. Confocal microscopy of intact HEK293 cells expressing TXNDC1 and Western analysis of subcellular fractions localized TXNDC1 primarily in the microsomal fraction in an endoplasmic reticulum (ER)-like staining pattern characterized by a diffuse network-like labeling of the cytoplasm and nuclear rim.
This Thioredoxin-related transmembrane protein 1 (TMX1) 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 Thioredoxin-related transmembrane protein 1 (TMX1) 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.
