Human 8-iso-PGF2α ELISA Kit Instructions

Human 8-iso-PGF2α ELISA KitFor the quantitative in vitro determination of Human 8-iso -prostaglandin F2 alphaconcentrations inserum - plasma - celiac fluid - tissue homogenate - body fluidFOR LABORATORY RESEARCH USE ONLY.NOT FOR USE IN DIAGNOSTIC PROCEDURES.This package insert must ELISAENZYME LINKED IMMUNOSORBENT ASSAYINTENDED USE AND TEST PRINCIPLEThis 8-iso-PGF2α ELISA kit is intended Laboratory for Research use only and is not for use indiagnostic 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 8-iso-PGF2α in the sample, this 8-iso-PGF2α ELISA Kit includes a set of calibration standards. The calibration standards are assayed at The same time as the samples andallow the operator to produce a standard curve of Optical Density versus 8-iso-PGF2αconcentration. 8-iso-PGF2α in the samples is then determined by comparing the OD of the samples to the standard curve. SAMPLE COLLECTION AND STORAGESSerum - Use a serum separator tube and allow samples to clot for 2 hours at room temperatureor overnight at 4°C before centrifugation for 20 minutes at approximately 2000×g. Removeserum and assay immediately or aliquot and store samples at -20°C. Avoiding freezethawcyclesPlasma - Collect plasma using heparin as an anticoagulant. Centrifuge samples for 30 minutes at2000×g at 2-8°C within 30 minutes Avoid collectionfreeze-thaw cycles.Cell culture supernates, tissue homogenate and other biological fluids - Removeparticulates by centrifugation and assay immediately or aliquot and store samples at -20°C.Avoid repeated freeze-thaw cycles. Note: The samples shoule be centrifugated dequately and no hemolysis or granule wasallowed.MATERIALS REQUIRED BUT NOT SUPPLIED1. 37 °C incubator2.

If samples generate values ​​higher than the highest standard, please dilute thesamples with Sample Diluent and repeat the assay.PRECAUTIONS1. Do not substitute reagents from one kit lot to another. Standard, conjugate and microtiterplates are matched for optimal performance. Use only the reagents supplied by man Uffluent.2. Allow kit reagents and materials to reach room temperature (20-25°C) before use. Do not use water baths to thaw samples or reagents.3. Do not use kit components beyond their expiration date.4. Use only deionized Do not remove microtiter plate from the storage bag until needed. Unused strips should be2stored at 2-8°C in their pouch with the desiccant provided.6. Use fresh disposable pipette tips for each transfer to Disposeable must have handled as potentially hazardous and capable of transmitting disease. Disposable gloves must be worn during the assay procedure, since no known test methodcan offer complete assurance that products Evided from Rat blood will not transmit infectiousagents., all blood derivatives should be considered potentially infectious and goodlaboratory practices should be followed.9. All samples should be disposed of in a The waste should be allowed to stand for a minimum of 30 minutes to inactivate the viruses before disposal.11. Substrate Solution is easily contaminated. If Abstrate B contain 20% acetone, keep this reagent away from sources of heat or flame.13. Remove all kit reagents from refrigerator and allow them to reach room temperature ( 20-25°C ).REAGENT PREPARATION AND STORAGEWash Solution (1X) - Dilute 1 volume of Wash solution (20X) with 19 volumes of deionized ordistilled water. Wash Solution is stable for 1 month at 2-8°C.ASSAY PROCEDURE1. Prepare all reagents before starting Iso recommended that all Standards andSamples be added in duplicate to the Microelisa Stripplate.2. Add 50μl of Standard or Sample to the appropriate wells. Blank well doesn't add anyting.3. Add 100μl of HRP-conjugate reagent to Standard wells and sa Mple wells except the blank well,cover with an adhesive strip and incubate for 60 minutes at 37°C.4. Wash the Microtiter Plate 4 times.Manual Washing - Remove incubation mixture by aspirating contents of the plate into a sink orproper waste container. Using a squirt bottle, fill each well completely with Wash Solution (1X), 3then aspirate contents of the plate into a sink or proper waste container. Repeat this procedure for a total of four times. After final wash, invert plate, and blot dry by Note: Hold the sides of the plate frame firmwhen washing the plate to assure that all strips remain securely in frame.Automated Washing - Aspirate all wells, then wash plates four times using Wash Buffer (1X).Always adjust your brush to aspirate as much liquid as possible and set fill volume at 350μL/well/wash. After final wash, invert plate, and blot dry by hitting plate. Isture appears.5. Add chromogen solution A 50μl and chromogen solution B 50μl to each well. Gently mix andincubate for 15 minutes at 37°C. Protect from light.6. Add 50μl 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 plateto ensure thorough mixing. 7. Read the Optical Density (OD) at 450 nm using a microtiter plate reader within 15 The standard curve is used to determine the amount in an unknown sample. The standard curve is generated by plotting the average OD (450 nm) obtained for each of the six standard concentrations on the vertical (X) axis versus the corresponding Concentrate on the horizontal(Y) axis.2. First, calculate the mean OD value for each standard and sample. All OD Values ​​aresubtracted by the mean value of the balnk well before result interpretation. Construct the standardcurve using graph paper or sta To determine the amount in each sample, first locate the OD value on the Y-axis and extenda horizontal line to the standard curve. At the point of intersection, draw a vertical line to the Xaxis 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. Intra-assay CV(%) and Inter-assay CV( %)are less than 15%.6. Assay range: 6.25 pg/mL – 200 pg/mL.47. Sensitivity: The minimum detectable dose of Human 8-iso-PGF2αis typically less than 1.0pg/mL.8. No. Significant cross-reactivity or interference was observed. 9. Storage: 2-8 ° C (Use frequently); six months (-20 ° C). 10.
