Rat GLUT4 (Glucose Transporter 4)CLIA Kit

This kit uses Sandwich-CLIA as the method. The micro CLIA plate provided in this kit has been pre-coated with an antibody specific to Rat Glut4 . Standards or samples are added to the appropriate micro CLIA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat Glut4 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 Rat Glut4, biotinylated detection antibody and Avidin-HRP conjugate will appear fluorescence. The Relative light unit (RLU) value is measured spectrophotometrically by the Chemiluminescence immunoassay analyzer. The RLU value is positively associated with the concentration of Rat Glut4. The concentration of Rat Glut4 in the samples can be calculated by comparing the RLU of the samples to the standard curve.

This kit recognizes Rat GLUT4 in samples. No significant cross-reactivity or interference between Rat GLUT4 and analogues was observed.

Typical Data

As the RLU 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.

RLU Average Corrected


Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Rat GLUT4 were tested 20 times on one plate, respectively.

Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Rat GLUT4 were tested on 3 different plates, 20 replicates in each plate.

Rat GLUT4 (Glucose Transporter 4)CLIA Kit (RTES00246) Assay procedure

    1. 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.
    2. Aliquot 100µl of standard solutions into the standard wells.
    3. Add 100µl of Sample / Standard dilution buffer into the control (zero) well.
    4. Add 100µl of properly diluted sample (serum, plasma, tissue homogenates and otherbiological fluids.) into test sample wells.
    5. Cover the plate with the sealer provided in the kit and incubate for 90 min at 37°C.
    6. 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.
    7. Aspirate or decant the solution from the plate and add 350µL of wash buffer to each welland incubate for 1-2 minutes at room temperature. Aspirate the solution from each well andclap the plate on absorbent filter paper to dry. Repeat this process 3 times. Note: a microplatewasher can be used in this step and other wash steps.
    8. Add 100µL of HRP Conjugate working solution to each well. Cover with a plate seal andincubate for 30 min at 37°C.
    9. Aspirate or decant the solution from each well. Repeat the wash process for five times asconducted in step 7.
    10. Add 100µL of Substrate mixture solution to each well. Cover with a new plate seal andincubate for no more than 5 min at 37°C. Protect the plate from light.
    11. Determine the RLU value of each well immediately.

Rat GLUT4 (Glucose Transporter 4)CLIA Kit (RTES00246) Protein Information

UniProt Protein Function:GLUT4: an integral membrane facilitative glucose transporter. One of 13 members of the human equilibrative glucose transport protein family. Its surface expression is regulated by insulin. Has two internalization sequences, a dileucine repeat present in the C-terminus and a FxxY motif in the amino-terminal end. Associates with an intracellular tubulo-vesicular compartment under low plasma conditions. The binding of insulin to the insulin receptor (a typosine kinase) leads to the rapid translocation of GLUT4 to the cell surface, increasing cellular glucose transport activity. Its translocation to the plasma membrane is also stimulated by exercise, but independent from insulin signaling. This insulin-independent pathway may be regulated by AMPK.
