Human LIPC (Lipase, Hepatic) 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 Human LIPC . 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 Human LIPC 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 LIPC, 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 Human LIPC. The concentration of Human LIPC in the samples can be calculated by comparing the RLU of the samples to the standard curve.

This kit recognizes Human LIPC in samples. No significant cross-reactivity or interference between Human LIPC 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 Human LIPC were tested 20 times on one plate, respectively.

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

Human LIPC (Lipase, Hepatic) CLIA Kit (HUES00343) 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.

Human LIPC (Lipase, Hepatic) CLIA Kit (HUES00343) Protein Information

UniProt Protein Function:LIPC: Hepatic lipase has the capacity to catalyze hydrolysis of phospholipids, mono-, di-, and triglycerides, and acyl-CoA thioesters. It is an important enzyme in HDL metabolism. Hepatic lipase binds heparin. Defects in LIPC are the cause of hepatic lipase deficiency (HL deficiency). A disorder characterized by elevated levels of beta-migrating very low density lipoproteins, and abnormally triglyceride-rich low and high density lipoproteins. Belongs to the AB hydrolase superfamily. Lipase family.
