Recommended storage for kit components is 2 - 8°C. See individual vials for long-term storage recommendations.

Once the standards and controls have been reconstituted, transfer contents into polypropylene vials. DO NOT STORE RECONSTITUTED STANDARDS OR CONTROLS IN GLASS VIALS. For long-term storage, freeze reconstituted standards and controls at £ -20°C. Avoid multiple (>2) freeze/thaw cycles.

DO NOT FREEZE Antibody-Immobilized Beads, Bead Diluent, Detection Antibody, and Streptavidin-Phycoerythrin.


Sodium Azide has been added to some reagents as a preservative. Although the concentrations are low, sodium azide may react with lead and copper plumbing to form highly explosive metal azides. On disposal, flush with a large volume of water to prevent azide build up.

A. A 25 m l per well of 1:400 diluted serum or plasma samples can be used. Calculated sample values should be multiplied by 400 as final sample concentration.

B. Preparation of Serum Samples:

After collecting blood samples, invert tube several times to mix. 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 £ -20şC. Avoid multiple (>2) freeze/thaw cycles. Use Assay Buffer to dilute serum samples prior to assay.

C. Preparation of Plasma Samples:

Plasma collection using EDTA as an anticoagulant is recommended. 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 £ -20şC. Avoid multiple (>2) freeze/thaw cycles. It is recommended to centrifuge plasma samples again at 3000 xg for five minutes prior to assay set up. Use Assay Buffer to dilute plasma samples prior to assay.

D. Avoid using samples with gross hemolysis or lipemia.

E. 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 ≥ 5seconds (equivalent to < 100 mmHg).

E. The standards prepared by serial dilution must be used within 1 hour of preparation. Use a fresh tip with each dilution. Discard any unused standards except the highest standard (standard 7) 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.

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.


A. Preparation of Human Adipokine Standard Cocktail

Reconsititute the Human Adipokine Standard Cocktail with 250 μl deionized water and allow the vial to set for about 5 minutes, invert the vial several times to mix gently. Votex and mix well. Transfer the standards to a microfuge tube labeled “Standard 7”. Label six polypropylene microfuge tubes “Standard 6”, “Standard 5”, “Standard 4”, "Standard 3", "Standard 2", and "Standard 1". Add 200 ml of Assay Buffer to each of the six tubes. Perform 5 times serial dilutions by adding 50 ml of the "Standard 7" to the "Standard 6" tube, mix well and transfer 50 ml of the "Standard 6" to the "Standard 5" tube, mix well and transfer 50 ml of the "Standard 5" to "Standard 4" tube, mix well and transfer 50 ml of the "Standard 4" pg/mlto the "Standard 3", mix well and transfer 50 ml of the "Standard 3"pg/mlto the "Standard 2" tube, mix well and transfer 50 ml of the "Standard 2" pg/mlto the "Standard 1". The 0 standard (Background) will be Assay Buffer.
