Bead count:
Bead Count per 400 small squares:
Side 1: ______ Side 2: ______
Total Volume (60ul)
5.75 ml
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 (ul)
1 sq. mm (400 small squares) x 0.1 mm (depth) x Number of Cytokines x
1000
i.e. Mean of duplicate bead count x volume beads added per well (ul)
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 50 ul beads per well:
Mean = 54
Calculation:
54 x 50
= 6750 beads/cytokine/well
0.1 x 4
______ x _50___
=
beads/cytokine/well
0.1 x 6
QA/QC: Beads/cytokine/well must be greater than 2000 to continue.
Preparation of Standard Curve
Made 1 set of standards.
Diluent used: ________
This is the most important part of the procedure. Be really accurate with volumes, i.e., no
bubbles in tip.
1. Lyophilised standard 1 Gp I reconstituted with _500_ ul _(diluent)_______, resulting in
22147 pg/ml IL-2.
Vortex gently 1-3 sec and incubate on ice for 30 min. Equilibrate 20 min. at RT.
Vortex gently. This master mix will serve as Standard 1 in the Broad PMT setting standard
curve.
Standard 1 = _256_ l of stock
+ ____ __144____ of diluent.
Time: ___________
Equilibrate:_______
Standard 2 = _100_ l of standard 1 + _____300____ of diluent. Start dilutions: ____
Standard 3 = _100_
l of standard 2
+ _____300____ of diluent.
Standard 4 = 100_
l of standard 3
+ _____ 300____ of diluent.
Standard 5 = _100_
l of standard 4
+ _____300____ of diluent.
Standard 6 = _100_
l of standard 5
+ _____300____ of diluent.
Standard 7 = _100_
l of standard 6
+ _____300____ of diluent.
Standard 8 = _100_ l of standard 7 + _____300____ of diluent.
Vol of Standard to add to wells: __50ul__
I ran 1 set of Blanks: 3 wells @ 50 l/well of_____.
Preparation of Controls (Spikes) Add 50 ul to each well. Diluent: Assay Buffer.
QA/QC: A high and low spike should be also be added to each plate as an internal Quality Control. As of 20 Apr
06 Dart Lab has used pooled supernants from Human DC experiments as Biological Controls.

Make enough Control for 1 plate: To make a 1/3 and 1/400 dilution and add 50ul to 6 wells:
Diluent: Assay Buffer.
1/3: Of the approved Hu DC/PBMC exp’t aliquot, take 100 ul + 200 ul Assay Buffer = 300ul
1/3 spike. Plate 50ul in triplicate. Use 10ul for 1/400 spike.
1/400: 1/3 x 1/133: Take 10 ul 1/3 spike + 1.32 ul Assay Buffer = 1.33 ul 1/400 spike. Plate 50
