Human UCHL1(Ubiquitin carboxyl-terminal hydrolase isozyme L1) ELISA Kit
This kit is based on Double antibody-Sandwich ELISA detection method and takes 4h assay time. The microplate provided in this kit has been precoated with anti UCHL1 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with UCHL1 bound to precoated antibody. Wash unbound components and add HRP-Streptavidin Conjugate (SABC). Wash unbound components again and add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Calculate the concentration of UCHL1 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

What’s the plate size in FineTest® ELISA Kits?
The ELISA plate follows the standard size of microplate: 127.64 mm x 85.60 mm x 14.22 mm(L x W x H).
How about the shelf life and stability of FineTest® ELISA Kits?
Valid for 12 months since the production date. For the shelf life of specific batch number, please check the label printed on the kit. Before delivery, all FineTest® ELISA Kits have been subject to strict quality test.
Which cloned antibodies for FineTest® ELISA Kits are used?
These information is proprietary. Please contact us to learn more about clonality (polyclonality or monoclonality) and host species.
Can I mix reagents from different batches of FineTest® ELISA Kits?
Not suggested. ELISA reagents are optimized for specific batch.
Can FineTest® ELISA Kits be used partially?
Yes. The ELISA plate is dismounted. Enough component volumes are offered by 96T ELISA kit, supporting two groups of standard curve.
How long can the diluted lyophilized standard be stored for continual use?
Used up within 12h.
Can standard curve be extended to any direction?
FineTest® can't support validation of standard concentration outside of standard curve. Ranges of standard curve have been validated among many batches and experimenters, showing stable and accurate performance. The lowest standard concentration is the minimized range for reliable detection results. Adding higher or lower concentration of standard may cause inconsistent signal or false positive.
Why does detection for serum/plasma sample by FineTest® ELISA Kits require for 1/2 dilution?
Matrix components in serum/plasma can affect detection results. Blocking components in sample dilution buffer can decrease or remove the interference. The dilution can reduce the matrix difference between sample and standard to get better accuracy.
What’s the half-life of protein in serum/plasma/cell culture supernatant?
FineTest® can't determine the half-life of protein in the sample(e.g. serum, plasma or cell culture supernatant). Usually, it's suggested to detect prepared sample immediately or aliquot sample to refrigerate in a disposable container. Avoid freeze-thaw cycle to prevent protein degradation.
What's the expected concentration for particularly analyzing my sample?
Due to the specificity of each sample, it's hard to forecast and depend on sample preparation as well as analytical characteristics. Please contact us to get detection data for reference.
How many samples can FineTest® ELISA Kits detect?
It depends on whether duplicate assay for your sample is required. Such as, you can detect 80 samples without duplication or 40 samples.
Why is sample loading conducted after equilibrating all kits’ components and samples to room temperature?
Temperature is the important factor for ELISA binding reaction. The reaction of samples at a consistent temperature requires for equilibrating all reagents to room temperature before the assay, including tested samples. Avoid the inaccurate ELISA assay results caused by temperature differences.
Why is duplicate assay suggested for ELISA assay?
To get more accurate assay results, it's strongly suggested to conduct duplicate assay for the standard and sample. Duplicate assay can calculate average value to ensure more accurate assay results and solve drift caused by misoperation during the assay. Calculation of CV evaluates experimental operation and precision of the ELISA kit.
How to get the standard curve with excellent linearity?
Follow the suggested method in the manual to store the standard. Before dissolving the standard, transient centrifugation is required to completely collect the powder. Confirm the fully dissolution and mixing of the standard(about 10min). Then, conduct steps of series dilution. Ensure the fully mixing and accurate pipetting in each step. Properly stop the staining. Choose suitable fitting equation to plot the standard curve.
Can ELISA plates be stacked together for incubation?
To keep the consistent environmental condition of all plates, stacking is not suggested during incubation.
Why is polypropylene tube used for standard dilution in some analyses?
Some proteins or analytes can bind with glass or polystyrene. However, they are not easy to bind with polypropylene tube.
When to stop ELISA reaction?
ELISA assay finally requires for enzyme-catalyzed substrate to complete the staining reaction. Stopping the reaction at the best time is the important factor for successful ELISA assay. When the blue complex appears after adding TMB substrate for 12min, read the O.D. absorbance at 620nm. The staining can be stopped, when the OD value of the darkest color at 620nm is between 0.8 - 0.9. The relevant OD value at 450nm for stopping the staining is between 2.0 - 2.5. If the OD value at 620nm is lower than 0.8, the staining duration can be properly extended.
Why is dual wavelength selected for reading in a microplate reader? What's the purpose of wavelength correction?
Dual wavelength for reading in ELISA assay mainly aims to remove non-specific background interference, and improve accuracy and reliability of the detection. FineTest® usually suggests to set the corrected wavelength as 570nm or 630nm in a microplate reader. The OD value may be higher when directly reading at 450nm. However, the accuracy is lower.
Why is 4 - pl curve fitting is required for generating standard curve?
FineTest® recommends to use ELISA curve fitting software and validate ELISA kit with 4 - pl curve fitting. 4 - pl curve fitting mainly aims to accurately describe the nonlinear dynamic characteristics of antigen - antibody binding. Thus, the quantitative accuracy of low or high concentration of sample is improved. Experimental errors are decreased. The reliability and reproducibility of assay results are ensured.
If sample OD value is higher than OD value of the highest point on the standard curve, what's the suggested solution?
Dilute the sample with dilution buffer and conduct the detection again. Ensure the detected value of the sample falls in the range of standard curve.
