Product Details
Intended Use
This kit is a sandwich enzyme immunoassay for in vitro quantitative measurement of FGFR1 in mouse tissue homogenates and other biological fluids.
Test Principle
The microtiter plate provided in this kit has been pre-coated with an antibody specific to FGFR1. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to FGFR1. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain FGFR1, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 ± 10 nm. The concentration of FGFR1 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

- Eppendorf Tubes for diluting samples.
- Deionized or distilled water.
- Absorbent paper for blotting the microtiter plate.
- Container for Wash Solution.
Storage of the kits
- For unopened kits: All the reagents should be stored at -20°C upon receipt.
- For opened kits: Once the kit is opened, the remaining reagents still need to be stored according to the above storage conditions. In addition, return the unused wells to the foil pouch containing the desiccant pack, and reseal along entire edge of zip-seal.
- For the expiration date of the kit, please refer to the label on the kit box. All components are stable until this date.
- It is highly recommended to use the remaining reagents within 1 month of opening.
Sample Collection and Storage
- Tissue homogenates - The preparation of tissue homogenates will vary depending upon tissue type. For this assay, tissues should be rinsed in ice-cold PBS (0.01 mol/L, pH 7.0-7.2) to remove excess blood thoroughly and weighed before homogenization. Mince the tissues to small pieces and homogenize them in 5-10 mL of PBS with a glass homogenizer on ice (Micro Tissue Grinders also work). The resulting suspension should be sonicated with an ultrasonic cell disrupter or subjected to 2 freeze/thaw cycles to further break the cell membranes. Then, centrifuge the homogenates for 5 minutes at 5000 × g. Remove the supernatant and assay immediately or aliquot and store at ≤-20°C.
- Other biological fluids - Centrifuge samples for 20 minutes at 1000 × g. Remove particulates and assay immediately or store samples in aliquots at -20°C or -80°C. Avoid repeated freeze/thaw cycles.
- Samples to be used within 5 days may be stored at 4°C, otherwise samples must be stored at -20°C (≤1 month) or -80°C (≤2 months) to avoid loss of bioactivity and/or contamination.
- Noticeable hemolysis will affect antibody-antigen reactions. Samples with any sign of hemolysis are not acceptable for this assay.
- When performing the assay, bring samples to room temperature.
Reagent Preparation
- Bring all kit components and samples to room temperature (18-25°C) before use.
- Standard - Reconstitute the Standard with 1.0 mL of Standard Diluent, keep for 10 minutes at room temperature, shake gently (not to foam). The concentration of the standard in the stock solution is 10 ng/mL. Prepare 7 tubes containing 0.5 mL Standard Diluent and use the diluted standard to produce a double dilution series according to the picture shown below. Mix each tube thoroughly before the next transfer. Prepare a dilution series with 7 points; for example: 10 ng/mL, 5 ng/mL, 2.5 ng/mL, 1.25 ng/mL, 0.625 ng/mL, 0.312 ng/mL, 0.156 ng/mL, and the last EP tube with Standard Diluent is the blank at 0 ng/mL.
- Detection Solution A and Detection Solution B - Detection Solutions A and B are already at the correct concentrations and do not need to be diluted further.
- Wash Solution - Dilute 20 mL of Wash Solution concentrate (30×) with 580 mL of deionized or distilled water to prepare 600 mL of Wash Solution (1×).
- TMB substrate - Aspirate the needed dosage of the solution with sterilized tips. Do not dump the residual solution back into the vial.
- Do not perform a serial dilution directly in the wells.
- Prepare standard within 15 minutes of performing the assay.
- Carefully reconstitute Standards according to the instruction, avoid foaming and mix gently until the crystals are completely dissolved.
- The reconstituted Standards can be used only once.
- If crystals have formed in the Wash Solution concentrate (30×), warm to room temperature and mix gently until the crystals are completely dissolved.
- Any contaminated water or container used during reagent preparation will influence the detection result.
Assay Procedure Summary

- Add 100 µL standard or sample to each well. Incubate 90 minutes at 37°C.
- Aspirate and add 100 µL Detection Solution A. Incubate 45 minutes at 37°C.

- Add 100 µL Detection Solution B. Incubate 45 minutes at 37°C.
- Aspirate and wash 5 times.
- Add 90 µL Substrate Solution. Incubate 15-25 minutes at 37°C.
- Add 50 µL Stop Solution. Read at 450 nm immediately.
Calculation of Results
Average the duplicate readings for each standard, control and sample, then subtract the average zero standard optical density. Construct a standard curve by plotting the mean O.D. and concentration for each standard and draw a best fit curve through the points on the graph or create a standard curve on log-log graph paper with FGFR1 concentration on the y-axis and absorbance on the x-axis. Using plotting software, (for instance, curve expert 1.30), is also recommended. If samples have been diluted, the concentration read from the standard curve must be multiplied by the dilution factor.
Product Data
Sensitivity
- The minimum detectable dose of FGFR1 is typically less than 0.061 ng/mL.
- The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined by adding two standard deviations to the mean optical density value of twenty zero standard replicates and calculating the corresponding concentration.
Specificity
- This assay has high sensitivity and excellent specificity for detection of FGFR1.
- No significant cross-reactivity or interference between FGFR1 and analogues was observed.
- Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between FGFR1 and all analogues, therefore, cross reactivity may still exist.
Precision
- Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level FGFR1 were tested 20 times on one plate, respectively.
- Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level FGFR1 were tested on 3 different plates, 8 replicates in each plate.
- CV (%) = SD/mean × 100
- Intra-Assay: CV<10%
- Inter-Assay: CV<12%
Stability
- The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage conditions.
- To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity, and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
