Human Protein disulfide-isomerase TMX3 (TMX3) ELISA Kit

The TMX3 gene encodes a protein of 454 amino acid residues that contains a predicted N-terminal signal sequence, a single domain with sequence similarity to thioredoxin and a CGHC active site sequence, a potential transmembrane domain, and a C-terminal KKKD tetrapeptide sequence that matches the classical KKXX-type consensus sequence for ER retrieval of type I transmembrane proteins. Endogenous TMX3 contains endoglycosidase H-sensitive glycans, localizes to the ER by immunofluorescence microscopy, and is present in the membrane fraction after alkaline extraction of the ER luminal content. The TMX3 transcript is found in a variety of tissues and is not up-regulated by the unfolded protein response.

Human Protein disulfide-isomerase TMX3 (TMX3) ELISA Kit has high sensitivity and excellent specificity for detection of Human TMX3. No significant cross-reactivity or interference between Human TMX3 and analogues was observed.

This Human Protein disulfide-isomerase TMX3 (TMX3) ELISA Kit employs a two-site sandwich ELISA to quantitate TMX3 in samples. An antibody specific for TMX3 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTMX3 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TMX3 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 TMX3 bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.
