PROCEDURAL NOTES/LAB.QUALITY CONTROL
When not in use, kit components should be stored refrigerated or frozen as indicated on vials or bottles. All reagents should be warmed to room temperature before use. Lyophilized standards should be discarded after use.
Once the desired number of strips has been removed, immediately reseal the bag to protect the remaining strips from edterioration.
Cover or cap all reagents when not in use.
Do not mis or interchange reagents between different lots.
Do not use reagents beyond the expiration date of the kit .
Use a clean disposable plastic pipette tip for each reagent, standard, or specimen addition in order to avoid cross-contamination, for the dispensing of H2SO4 and substrate solution, avoid pipettes with metal parts.
Use a clean plastic container to prepare the washing solution.
Thoroughly mix the reagents and samples before use by agitation or swirling.
All residual washing liquid must be drained from the wells by efficient aspiration or by decantation followed by tapping the plate forcefully on absorbent paper. Never insert absorbent paper directly into the wells.
The TMB solution is light sensitive. Avoid prolonged exposure to light, also, avoid contact of the TMB solution with metal to prevent colour development. Warning TMB is toxic avoid direct contact with hands. Dispose off properly. If a dark blue colour develops within a few minutes after preparation, this indicates that the TMB solution has been contaminated and must be discarede. Read absorbances within 1 hour after completion of the assay.
When pipetting reagents, maintain a consistent order of addition from well-to-well. This will ensure equal incubation times for all wells.
Respect incubation times described in the assay procedure.
SPECIMEN COLLECTION\ PROCESSING AND STORAGE
Serum---Avoid any inintentional stimulation of the cells by the procedure. Use pyrogen\endotoxin free collecting tubes. Serum should be removed rapidly and carefully from the red cells after clothing. For that, after clothing, centrifuge at approximately 1000×g for 10 min and remove serum.
Plasma---EDTA\ citrate and heparin plasma can be assayed. Spin samples at 1000×g for 30 min remove particulates. Harvest plasma.
Cell culture supernatants---Remove particulates and aggregates by spinning at approximately 1000×g for 10 min.
Storage---If not analyzed shortly after collection, samples should be aliquoted(250-500ul) to avoid freeze-thaw cycles and stored frozen at -70℃. Avoid multiple freeze-thaw cycles of frozen specimens. When possible, avoid use of badly hemolyzed or lipemic sera. If large amounts of particles are present, this should be removed prior to assay by centrifugation or filtration.
Recommendation---Do not thaw by heating at 37℃ or 56℃. Thaw at room temperature and make sure that sample is completely thawed and homogenous before assaying.
PREPARATION OF REAGENTS
Standards: Standard have to be reconstituled with the volume of standard buffer diluent indicated on the vial. This reconstitution produces a stock solution of 800IU/L COX-1. Allow standard to stand for 5
minutes with gentle swirling prior to making dilutions. Serial dilutions of standard must be made before each assys and cannot be stored.
800 IU/L （6 Standard） Original density 50ul。
400 IU/L （5 Standard） 100ul 6 Standard +100ul diludent
200 IU/L （4 Standard） 100ul 5 Standard +100ul diludent
100 IU/L （3 Standard） 100ul 4 Standard +100ul diludent
50 IU/L （2 Standard） 100ul 3 Standard +100ul diludent
25 IU/L （1 Standard） 100ul 2 Standard +100ul diludent
0 IU/L Blank Control 50ul。
Washing buffer 50×concentrate: Dilute 50 times in distilled water.
Before use, mix all reagents thoroughly without making foam.
Determine the number of microwell strips required to test the desired number of samples,plus appropriate number of wells needed for running blanks standards. Each sample, standard and blank should be assayed in duplicate. Remove sufficient microwell strips from the pouch.
Add 50ul of standard diluent to standard wells B1,B2, C1,C2, D1,D2, E1, E2, F1,F2. Reconstitute standard vial with the appropriate volume as described in the chapter reagents preparation. Preparation. Pipet 100ul of standard into wells A1 and A2 (see plate scheme below). Transfer 50ul from A1 and A2 to B1 and B2 wells. Mix the contents by repeated aspirations and ejections. Take care not to scratch the inner surface of microwells. Repat this procedure from the wells B1,B2 to wells C1,C2 and from wells C1,C2 to D1,D2 and so on creating two parallel rows of COX-1 standard dilutions ranging，Add 50ul of standard diluent to the bland wells.
Dilute samples 1:1 distribing 50ul of sample into 50ul of dilluent ,Add 50ul of diluted sample to wells..
Add 50ul of diluted biotinylated anti-COX-1 to all wells.
Cover with a plate vover and incubate for 1 hour at 37℃.
Remove the cover and wash the plate as follows: ⑴ aspirate the liquid from each well, ⑵ dispensse 0.3ml of washing solution into each well. ⑶ Aspirate again the contet of each well after 0.5 minute. ⑷ Repeat steps ⑵ and ⑶ three times.
Distribute 80ul of streptavidin-HRP solution to all wells, including blank wells.
Cover and incubate 30 min at 37℃.
Remove the cover and empty wells, Wash microwell strips according to step, Proceed immediately to the next step.
Add 50ul Substrate A and Substrate B to each well。Incubate for 10 min at 37℃。
The enzyme-substrate reaction is stopped by quickly pipetting 50ul of H2SO4. stop reagent into each well, including the blank wells, to completely and uniformly inactivate the enzyme. Results must be red immediately after the addition of H2SO4.
Read absorbance of each well on a spectrophotometer using 450nm as the primary wavelength and optionally 620nm (610nm to 650nm is acceptable ) as the reference wavelength.
