Features & Benefits
Human Serine palmitoyltransferase 3 (SPTLC3) ELISA Kit has high sensitivity and excellent specificity for detection of Human SPTLC3. No significant cross-reactivity or interference between Human SPTLC3 and analogues was observed.
Background
SPTLC3 orthologs were found in rat, mouse, and dog. Quantitative real-time PCR of human tissues showed highest expression in placenta, followed by skin, adrenal gland, testis, uterus, salivary gland, prostate, and kidney, lower expression in all other tissues, and no expression in peripheral blood cells and bone marrow. SPTLC3 and SPTLC2 showed different expression patterns, possibly reflecting tissue-specific requirements of sphingolipid synthesis. Western blot analysis revealed SPTLC3 expression in human trophoblast cell lines. Overexpression of SPTLC3 in HEK293 cells, which have little endogenous SPTLC3, resulted in increased SPT activity by 2- to 3-fold. Expression of an SPTLC3-specific siRNA in HepG2 cells and human trophoblast cells significantly decreased SPT activity, indicating that SPTLC3 plays a role in SPT activity.
This Serine palmitoyltransferase 3 (SPTLC3) 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 Serine palmitoyltransferase 3 (SPTLC3) 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.
