VI. SPECIMEN COLLECTION, PREPARATION AND STORAGE
A. 10 m l per well diluted serum, plasma or cell culture supernatant or extract can be used. The sample dilution of fat tissue/cell extracts and culture media may vary. 1:5000 dilution in Assay Buffer is recommended for serum or plasma.
Recommended Dilution Method (1:5000)
1. Add 5 m l serum or plasma to 495 m l Assay Buffer for a 1:100 dilution.
2. Add 5 m l of 1:100 diluted sample to 245 m l Assay Buffer for a final dilution of 1:5000.
B. Preparation of Tissue Culture Supernatant:
Centrifuge the sample to remove debris and assay immediately or aliquot and store samples at £ -20șC. Avoid multiple (>2) freeze/thaw cycles. Tissue Culture Supernatant may require a dilution with the appropriate medium prior to assay.
C. Preparation of Serum Samples:
After collecting blood 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 £ -20șC. Avoid multiple (>2) freeze/thaw cycles. Use Assay Buffer to dilute serum samples prior to assay. (See Section VI, A)
D. Preparation of Plasma Samples:
Plasma collection using EDTA as an anticoagulant is recommended. After collecting blood samples, invert tube several times to mix. Centrifuge for 10 minutes at 1000 xg within 30 minutes of blood collection. Remove plasma and assay immediately or aliquot and store samples at £ -20șC. Avoid multiple (>2) freeze/thaw cycles. Use Assay Buffer to dilute plasma samples prior to assay. It is recommended to centrifuge samples again at 3000 xg for five minutes prior to assay setup. (See Section VI, A)
E. Avoid using samples with gross hemolysis or lipemia.
F. Care must be taken when using heparin as an anticoagulant, since an excess will provide falsely high values.
Use no more than 10 IU heparin per ml of blood collected.
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.
A. The Antibody-Immobilized Beads are light sensitive, so the assay plate containing beads must be covered with aluminum foil during all incubation steps.
B. The bottom of the Microtiter Filter Plate should not be in contact with any absorbent material during assay set-up or incubation times. Set the plate on a plate cover or any other plate holder to raise the plate from the surface.
C. After the wash steps, dry the bottom of the Microtiter Filter Plate by using paper towels or absorbent pads to prevent any leakage due to capillary action.
D. 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).
E. The standards prepared by serial dilution must be used within 1 hour of preparation. Discard any unused standards except the 50 ng/ml stock standard which may be stored at £ -20° C for 1 month and at £ -80° C for greater than one month.
F. Any unused mixed Antibody-Immobilized Beads may be stored in the bead mix bottle at 2-8° C for up to one month.
G. 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.
H. If the plate cannot be read on the same day as the assay was finished, do the final bead suspension in 100 ml Sheath Fluid, seal the plate, cover with aluminum foil, and store at 2-8° C for up to 24 hours. Prior to reading, agitate the plate on the plate shaker at room temperature for 10 minutes.
I. The titer 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 in a 0.3 cm orbit.
J. 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 to reading an assay.
K. 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.
VIII. PREPARATION OF REAGENTS FOR IMMUNOASSAY
A. Preparation of Mouse Adipokine Standard Cocktail
Open lyophilized Standard vial carefully. Reconstitute the Mouse Adipokine Standard Cocktail with 250 μl deionized water into the glass vial to give a 50,000 pg/ml concentration of Standard stock. Invert the vial a few times and let it sit for 5 minutes. Transfer the standard to a microfuge tube labeled with 50,000 pg/ml Standard. After votexing, perform 4 times serial dilution as follows:
Label six polypropylene microfuge tubes 12,500, 3,125, 781.3, 195.3, 48.8, 12.2. Add 150 ul of Assay Buffer to each of the six tubes. Add 50 ml of the 50,000 (pg/ml) standard to the "12,500" tube, mix well and transfer 50 ml of the "12,500" standard to the "3,125" tube, mix well and transfer 50 ml of the "3,125" standard to the "781.3" tube, mix well and transfer 50 μl of the 781.3" standard to "195.3" tube, mix well and transfer 50 ml of the "195.3" pg/mlstandard to the "48.8" tube, mix well and transfer 50 ml of the "48.8" pg/mlstandard to the "12.2" tube. The 0 standard (Background) will be Assay Buffer.
