11. Luminex Instrument
A. A maximum of 25 m l per well of serum or plasma can be used. Tissue culture or other media may also be used.
B. Preparation of Tissue Culture Supernatant:
Centrifuge the sample to remove cell debris and run the assays immediately or aliquot and store samples at £ -20ºC. Avoid multiple (>2) freeze/thaw cycles. Tissue culture supernatant may require a dilution with the appropriate control medium prior to assay.
C. Preparation of Mouse Serum or Plasma Samples:
Allow the blood to clot for at least 30 minutes before centrifugation for 10 minutes at 1000 xg. Remove serum and assay immediately or aliquot and store samples at £ -20ºC. Avoid multiple (>2) freeze/thaw cycles. It is recommended to centrifuge samples prior to assay setup. If serum or plasma samples need to be diluted, the Serum Matrix should be used as the sample diluent. Additional Serum Matrix is available from LINCO Research.
D. All samples must be stored in polypropylene tubes. DO NOT STORE SAMPLES IN GLASS.
To obtain reliable and reproducible results, the operator should carefully read this entire manual and fully understand all aspects of each assay step before attempting to run the assay. The following notes should be reviewed and understood before the assay is set-up.
A. The Antibody-Immobilized Beads are light sensitive and must be covered with aluminum foil at all times. Cover the assay plate containing beads with aluminum foil during all incubation steps.
B. It is critical to allow all reagents to warm to room temperature (20-25° C) before use in the assay.
C. The bottom of the Microtiter Filter Plate should not be in direct contact with any absorbent material during assay set-up or incubation times. The plate can be set on the non-flat side of the plate cover or any other plate holder to raise the plate from the surface.
D. After the wash steps, keep the bottom of the Microtiter Filter Plate clean by blotting on paper towels or absorbent pads to prevent any leakage during assay set-up and incubation steps due to capillary action.
E. Keep the vacuum suction on the plate as low as possible. It is recommended to have a vacuum setting that will remove 200 ml of buffer in > 5 seconds (equivalent to < 100 mmHg).
After hydration, all standards and controls must be transferred to polypropylene tubes.
G. The standards prepared by serial dilution must be used within 1 hour of preparation. Discard any unused standards except the 10 ng/ml stock standard which may be stored at £ -20° C for 1 month and at £ -80° C for greater than one month.
H. During the preparation of the standard curve, make certain to vortex the higher concentration well before making the next dilution. Use a fresh tip with each dilution.
I. The plate should be read immediately after the assay is finished. Delay in reading the plate may result in decreased signals and sensitivities for some cytokines.
J. The titre plate shaker should be set at a speed to provide maximum agitation without splashing of liquid outside the wells. For the recommended plate shaker, this would be a setting of 5-7 which is approximately 500-800 rpm.
K. Ensure the needle probe is clean. This may be achieved by sonication and/or Alcohol Flushes. Adjust probe height to the Lincoplex filter plate prior toe reading an assay.
L. For cell culture supernatants or tissue extraction, use the culture or extraction medium as matrix in blank, standard curve and controls. If samples are diluted in Assay Buffer, use the Assay Buffer as matrix.
A. Preparation of Antibody-Immobilized Beads
Antibody-Immobilized Beads are premixed. Sonicate and/or vortex before use.
B. Preparation of Mouse Cytokine Standard Cocktail
1.) Before use, reconstitute the Mouse Cytokine Standard Cocktail with 250 ml Deionized Water to give a 10,000 pg/ml concentration of standard. Invert the vial several times to mix. Vortex the vial for 10 seconds. Allow the vial to set for 5-10 minutes, and then transfer the standard to an appropriately labeled polypropylene microfuge tube. This will be used as the 10,000 pg/ml standard; the un-used portions may be stored at £ -20° for up to one month.
2). Preparation of Working Standards
Label five polypropylene microfuge tubes 2000, 400, 80, 16, and 3.2 pg/ml. Add 200 ml of Assay Buffer to each of the five tubes. Prepare serial dilutions by adding 50 ml of the 10,000 pg/ml reconstituted standard to the 2000 pg/ml tube, mix well and transfer 50 ml of the 2000 standard to the 400 pg/ml tube, mix well and transfer 50 ml of the 400 standard to the 80 pg/ml tube, mix well and transfer 50 ml of the 80 standard to 16 pg/ml tube, mix well and transfer 50 ml of the 16 pg/ml standard to the 3.2 pg/ml tube and mix well. The 0 pg/ml standard (Background) will be Assay Buffer.

C. Preparation of Controls
Before use, reconstitute each Mouse Cytokine Control I and Mouse Cytokine Control II with 250 ml deionized water. Invert the vials several times to mix and vortex. Allow the vials to set for 5-10 minutes and then transfer the controls to appropriately labeled polypropylene microfuge tubes. Unused portions may be stored at £ -20° for up to one month.
D. Preparation of Wash Buffer
Bring the 10X Wash Buffer to room temperature and mix to bring all salts into solution. Dilute 30 ml of 10X Wash Buffer with 270 ml deionized water. Store unused portions at 2-8° C for up to one month.
E. Preparation of Serum Matrix
This step is required for serum or plasma samples only.
Add 1.0 mL of deionized water to the vial containing the lyophilized Serum Matrix, gently swirl the bottle and then place the bottle on bench for 5 to 10 min.
Prior to beginning this assay, it is imperative to read this protocol completely and to thoroughly understand the Technical Guidelines outlined in Section VII.
Allow all reagents to warm to room temperature (20-25° C) before use in the assay.
1. Diagram placement of Standards, 0 (Background), 3.2, 16, 80, 400, 2000, and 10,000 pg/ml, Controls I and II, and samples on Well Map Worksheet in a vertical configuration. (Note: the instrument will only read the 96-well plate vertically). It is recommended to run the assay in duplicate.
2. Block the filter plate by pipetting 200 µL of Assay Buffer into each well of the microtiter plate. Seal and mix on a plate shaker for 10 minutes at room temperature (20-25° C).
3. Remove Assay Buffer by vacuum. (NOTE: DO NOT INVERT PLATE). Remove any excess Assay Buffer from the bottom of the plate by blotting on an absorbent pad or paper towels.
4. Add 25 µL of Assay Buffer to the 0 Standard (Background).
5. Add 25 µL of Assay Buffer to the Sample wells.
6. Add 25 µL of each Standard or Control into the appropriate wells.
7. Add 25 µL of an appropriate matrix solution to the Background, Standards, and Control wells. When assaying serum or plasma samples, use the Serum Matrix provided in the kit as the matrix solution and sample diluent. When assaying non-blood samples (tissue or cell culture medium, tissue extracts), use the same matrix as the samples for the Background, Standards, and Control wells and as the sample diluent. (For example, use control tissue culture medium for tissue culture samples; use extract buffer for tissue extract samples.)
8. Add 25 µL of sample into the appropriate wells.
9. Vortex and/or sonicate Bead Bottle for approximately 30 – 60 seconds and add 25 µL of Mixed Beads to each well. (Note: during addition of Mixed Beads, shake bead mix intermittently to avoid settling.)
10. Seal, cover with aluminum foil, and incubate with agitation on a plate shaker for 2 hours at room temperature (20-25° C) or overnight (16-18 hours) at 2-8° C for serum-free samples. For serum or serum-containing samples, it is recommended to increase incubation time to 16-18 hours at 2-8° C for better sensitivity.
11. Gently remove fluid by vacuum filtration.
12. Wash plate 2 times with 200 µL/well of Wash Buffer, removing Wash Buffer by vacuum filtration between each wash. Remove any excess Wash Buffer from the bottom of the plate using an absorbent pad or paper towels.
13. Add 25 µL of Detection Antibody Cocktail into each well. (Note: allow the Detection Antibody to warm to room temperature, 20-25° C, prior to addition.)
14. Seal, cover with aluminum foil, and incubate with vigorous agitation on a plate shaker at room temperature (20-25° C) for 60 minutes. DO NOT VACUUM AFTER INCUBATION.
15. Add 25 µL Streptavidin-Phycoerythrin to each well containing the 25 µL of Detection Antibody Cocktail.
16. Seal, cover with aluminum foil, and incubate with agitation on a plate shaker for 30 minutes at room temperature (20-25° C).
17. Gently remove all contents by vacuum.
18. Wash plate 3 times with 200 µL/well Wash Buffer, removing Wash Buffer by vacuum filtration between each wash. Wipe any excess buffer on the bottom of plate with a paper towel or tissue.
19. Add 100 µL of Sheath Fluid to all wells. Cover with aluminum foil and resuspend the beads by shaking on a plate shaker for 5 minutes.
20. Run plate on Luminex Instrument. Read 50 beads per bead set in 50 µL sample size.
21. Save the data and evaluate the median fluorescence units using appropriate curve-fitting software. A 5 or 4-parameter logistic method or cubic spline method is recommended.
