Description
Human G6PD (Glucose 6 Phosphate Dehydrogenase) ELISA Kit
The Human G6PD (Glucose-6-Phosphate Dehydrogenase) ELISA Kit is specifically designed for the accurate measurement of G6PD levels in human samples, including serum, plasma, and cell culture supernatants. With its high sensitivity and specificity, this kit ensures precise and consistent results, making it an invaluable tool for a variety of research applications.G6PD is a key enzyme involved in the pentose phosphate pathway and plays a crucial role in protecting cells from oxidative stress. Mutations in the G6PD gene are associated with G6PD deficiency, a common genetic disorder that can lead to hemolytic anemia in response to certain triggers such as infections or certain medications.
By detecting G6PD levels, researchers can gain insights into cellular metabolism, oxidative stress responses, and potential therapeutic targets for conditions such as G6PD deficiency and other related disorders. The Human G6PD ELISA Kit provides a reliable and efficient method for studying G6PD activity and its implications in various disease states.

This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human G6PD. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human G6PD and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human G6PD, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding Stop Solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human G6PD. The concentration of Human G6PD in samples can be calculated by comparing the OD of the samples to the standard curve.
| UniProt Protein Function: | G6PD: glucose-6-phosphate dehydrogenase. A cytosolic enzyme encoded by a housekeeping X-linked gene whose main function is to produce NADPH, a key electron donor in the defense against oxidizing agents and in reductive biosynthetic reactions. G6PD is remarkable for its genetic diversity. Many variants of G6PD, mostly produced from missense mutations, have been described with wide ranging levels of enzyme activity and associated clinical symptoms. G6PD deficiency may cause neonatal jaundice, acute hemolysis, or severe chronic non-spherocytic hemolytic anemia. Two splice variant isoforms have been described. The long isoform is found in lymphoblasts, granulocytes and sperm. |

| NCBI Summary: | This gene encodes glucose-6-phosphate dehydrogenase. This protein is a cytosolic enzyme encoded by a housekeeping X-linked gene whose main function is to produce NADPH, a key electron donor in the defense against oxidizing agents and in reductive biosynthetic reactions. G6PD is remarkable for its genetic diversity. Many variants of G6PD, mostly produced from missense mutations, have been described with wide ranging levels of enzyme activity and associated clinical symptoms. G6PD deficiency may cause neonatal jaundice, acute hemolysis, or severe chronic non-spherocytic hemolytic anemia. Two transcript variants encoding different isoforms have been found for this gene.

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e. g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

- Set standard, test sample and control (zero) wells on the pre-coated plate and record theirpositions. It is recommended to measure each standard and sample in duplicate. Note: addall solutions to the bottom of the plate wells while avoiding contact with the well walls. Ensuresolutions do not foam when adding to the wells.
- Aliquot 100µl of standard solutions into the standard wells.
- Add 100µl of Sample / Standard dilution buffer into the control (zero) well.
- Add 100µl of properly diluted sample (serum, plasma, tissue homogenates and otherbiological fluids) into test sample wells.
- Cover the plate with the sealer provided in the kit and incubate for 90 min at 37°C.
- Aspirate the liquid from each well, do not wash. Immediately add 100µL of BiotinylatedDetection Ab working solution to each well. Cover the plate with a plate seal and gently mix. Incubate for 1 hour at 37°C.
