Dart Lab’s Millipore Luminex Record Sheet For the Millipore protocol go to www.millipore.com. Type in your kit number and go to the protocol page. Analytes: Custom 10-plex IL-1ra, IL-1a, IL-6, IL-8, IL-10, MCP-1, MIP-1a, MIP-1b, Rantes, TNFa Supplier: Millipore Principal Investigator: 1 Plate Type of Samples: Plate: 1 of 1 Date: # sample wells on Plate 1: 63 Total # wells on Plate 1: 96. Standards=18; Samples= 63; Blanks=3; Controls=12 Standards Plate 1: Use ______ as medium Samples this plate: Kit Used: Medium: Calibration: Broad Standard Cat #: Detection Antibody Catalog #: Expiration: Expiration: Millipore Quality Control 1 Lot #: Millipore Quality Control 2 Lot #: Preparation of Plate Prewet the filter plate by pipetting 200 l of Wash Buffer into each well of the Luminex Plate. Seal and shake on a plate shaker for 10 minutes at room temperature. Preparation of Beads Sonicate the antibody bead vial for 30 sec; vortex for 1 min. Volume to be added to wells: 25 l For this 10-plex, there are 10vials/kit = 10 vials. Take 60 l from each vial. 0.060 ml x 10vials = 0.6 ml beads. Bring this up to 3ml (for 1 plate) by adding 2.4 ml Bead Diluent for Hu kit, Assay Buffer for Mo kit. # wells 96 Beads 0.6 ml Diluent 2.4 ml Total Bead Volume 3.0 ml Bead count: Bead Count per 400 small squares: Side 1: ______ Side 2: ______ Mean: ______ Use the following formula to calculate if there are sufficient beads for the assay: Mean of duplicate bead count x 1000 (mm3 to cc3 conversion factor) x volume beads added per well (l) 1 sq. mm (400 small squares) x 0.1 mm (depth) x Number of Cytokines i.e. Mean of duplicate bead count x volume beads added per well (l) 0.1 x number of cytokines = beads/cytokine/well Example: if doing a 4-plex, have counted 56 and 52 beads in 400 small squares, and added 25 l beads per well: Mean = 54 54 x 25 = 3375 beads/cytokine/well 0.1 x 4 Calculation: ______ x 25 = beads/cytokine/well 0.1 x 10 QA/QC: Beads/cytokine/well must be greater than 2000 to continue.

Kathy Smith Page 1 Dart Lab’s Millipore Luminex Record Sheet Preparation of Standard Curve Diluent used: Deionized water Dilution factor: 1:5 This is the most important part of the procedure. Be really accurate with volumes, i.e., no bubbles in tip. Reconstitute lyophilised standard 1 with 250 l deionized water resulting in 10,000 pg/ml for all 10 analytes. Invert vial 2-3x to ensure complete reconstitution. Vortex the vial for 10 seconds. Allow the vial to sit for 5 10 min. Transfer the standard to an appropriately-labeled microfuge tube. Vortex gently. This master mix will serve as 10,000 pg/ml Standard I in the Low PMT setting standard curve. Standard 1 = 250 l of reconstituted lyophilised standard Standard 2 = 50 l of standard 1 + 200 l of Assay Buffer Standard 3 = 50 l of standard 2 + 200 l of Assay Buffer Standard 4 = 50 l of standard 3 + 200 l of Assay Buffer Standard 5 = 50 l of standard 4 + 200 l of Assay Buffer Standard 6 = 50 l of standard 5 + 200 l of Assay Buffer Vol of Blank to add to wells: 25 l; Time: ____ Blank = 25 l of Assay Buffer in 3 wells. Preparation of Controls Use Quality Control 1 and 2 provided in kit as Controls, as well as Dart Lab Control at Neat and 1:100. Make enough for 3 wells on 1 plate: To make a 1/100 dilution and add 25 l to 3 wells: Diluent: Assay Buffer. 1/100: Of the approved hu DC exp’t aliquot, take 10 l spike + 990 l Assay Buffer = 1.0 ml 1/100 spike. Aliquot 25 l in 3 wells on 1 plate. Dilutions: Neat X Low 1/100 X. Preparation of Samples Vol of Samples to add to wells: 25 l of samples Are any samples diluted? No. Indicate on BioPlex software protocol.
