Scientific Background
TOMM34 is involved in the import of precursor proteins into mitochondria. The encoded protein has a chaperone-like activity, binding the mature portion of unfolded proteins and aiding their import into mitochondria. This protein, which is found in the cytoplasm and sometimes associated with the outer mitochondrial membrane, has a weak ATPase activity and contains 6 TPR repeats. hTom34 is displayed on the surface of mitochondria and is resistant to extraction under alkaline conditions. Antibodies raised against hTom34 specifically inhibit in vitro import of the mitochondrial precursor protein p.
Assay Principle
This assay employs a two-site sandwich ELISA to quantitate TOMM34 in samples. An antibody specific for TOMM34 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTOMM34 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TOMM34 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TOMM34 bound in the initial step. The color development is stopped and the intensity of the color is measured.

Safety & Regulatory
Handle reagents in accordance with institutional biosafety guidelines. Refer to the Safety Data Sheet (SDS) for complete hazard and handling information. Contains components that may require special disposal procedures per local regulations.
This kit is validated for use with serum, plasma, cell culture supernatant, tissue homogenate. For unlisted matrices (e.g., tissue lysate, urine), perform a spike-and-recovery experiment to confirm assay performance before generating reportable data. Sample dilution in the kit's provided diluent is recommended to minimize matrix interference.
The minimum detectable concentration (sensitivity) of this kit is Request Information. Values below this threshold should be reported as below the limit of detection (<LOD) and should not be extrapolated from the standard curve.
The total assay time from sample addition to absorbance reading is approximately 3.5–5 hours, including all incubation, wash, and substrate steps. Hands-on time is typically 1–2 hours; most steps involve passive plate incubation. Plan the assay as a single uninterrupted session for best results.
Standard components of this Sandwich ELISA Kit typically include: pre-coated microplate (96-well strip format), lyophilized or liquid recombinant TOMM34 standard, detection antibody, streptavidin-HRP conjugate, TMB substrate, stop solution, wash buffer concentrate, and sample/standard diluent. Refer to the kit insert or datasheet for the exact component list and storage requirements.
This kit uses colorimetric (TMB/HRP) detection and requires a standard microplate absorbance reader capable of measuring at 450 nm. A reference wavelength of 570 nm or 630 nm is recommended to reduce background. No specialized fluorescence or luminescence reader is needed. Ensure the instrument is calibrated and the plate is clean and free of condensation before reading.
