Human hypoxia-inducible factor 1α （HIF-1α） ELISA Kit

instruction

Intended use

This HIF-1α ELISA kit is intended Laboratory for Research use only and is not for use in diagnostic or therapeutic procedures.The Stop Solution changes the color from blue to yellow and the intensity of the color is measured at 450 nm using a spectrophotometer. In order to measure the concentration of HIF-1α in the sample, this HIF-1α ELISA Kit includes a set of calibration standards. The calibration standards are assayed at the same time as the samples and allow the operator to produce a standard curve of Optical Density versus HIF-1α concentration. The concentration of HIF-1α in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Sample collection and storages

Serum - Use a serum separator tube and allow samples to clot for 30 minutes before centrifugation for 10 minutes at approximay 3000×g. Remove serum and assay immediay or aliquot and store samples at -20℃ or -80℃.Avoid repeated freeze-thaw cycles

Plasma - Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples for 30 minutes at 3000×g at 2-8℃ within 30 minutes of collection. Store samples at -20℃or -80℃. Avoid repeated freeze-thaw cycles.

Cell culture supernates and other biological fluids - Remove particulates by centrifugation and assay immediay or aliquot and store samples at -20℃or -80℃. Avoid repeated freeze-thaw cycles.

Note: The samples shoule be centrifugated dequay and no hemolysis or granule was allowed.

Reagent preparation

20×wash solution:Dilute with Distilled or deionized water 1:20.

Assay procedure

1. Prepa re all reagent s before starting ass ay procedure. It is recommended that all Standa rds and Sa mples be added in duplica te to the Micro elisa Stripp l a t e.

2. Add standard: Set Standard wells, testing sample wells. Add standard 50μl to standard well.

3. Add Sample: Add testing sample 10μl Then add sample diluent 40μl to testing sample well; Blank well doesn’t add anyting.

4. A dd 10 0μ l of HRP-conjugate reagent to each well, c over with a n adhesive strip and incuba te for 60 minutes at 37°C .

4. Aspirate each well and wash, repeating the process four times for a total of f ive washes. Wash by filling each well with Wash Solution （400 μ l ） using a squirt bottle, manifold dispenser or autowasher. Complete removal of liquid at each step is essential to goo d performance. After the last wash, remove any remaining Wash Solution by aspirating or decanting. Invert the plate and blot it against clean paper towels.

5. Add chromogen solution A 50μl and chromogen solution B 50μl to each well. Gently mix and incubate for 15 minutes at 37°C . Protect from light .

6. Add 50 μ l Stop Solution to each well. The color in the wells should change from blue to yellow. If the color in the wells is green or the color change does not

appear uniform, gently tap the plate to ensure thorough mixing .

7. R ead the Optical Density （ O.D.） at 450 nm using a m icrotiter pl a te reader within 15 m i nutes.

C alculation of results

1. This standard curve is used to determine the amount in an unknown sample. The standard curve is generated by plotting the average O.D. （450 nm） obtained for each of the six standard concentrations on the vertical （Y） axis versus the corresponding concentration on the horizontal （X） axis.

2. First, calculate the mean O.D. value for each standard and sample. All O.D. values, are subtracted by the mean value of the zero standard before result interpretation. Construct the standard curve using graph paper or statistical software.

3. To determine the amount in each sample, first locate the O.D. value on the Y-axis and extend a horizontal line to the standard curve. At the point of intersection, draw a vertical line to the X-axis and read the corresponding concentration.

4. Any variation in operator, pipetting and washing technique, incubation time or temperature, and kit age can cause variation in result. Each user should obtain their own standard curve.

5. The sensitivity by this assay is 1.0 pg/mL.

6. Standard curve

Storage ： 2 -8 ℃ .
