BM057-0 8-4-09 T Reg Studies (Day 3)

  • Divided cell culture wells
    • Mixed cells in each well by pipetting up and down several times.
    • Transferred 250 uL of cells in medium to 3 new wells labeled for each condition; this leaves 250 uL of cells in medium in the original wells.
    • Added 750 uL of AIM-V to each well to bring the total volume per well to 1 mL.

Placed back in the incubator.

BM058-0 8-3-09 48 Hour Culture (Day 2)

  • Cells from the 48 hour culture were harvested, processed as per the CD25 Selection and RNA Extraction protocol and stored in cluster tubes at -80.
    • One sample per stimulant condition:
      • Stimulant 1: caseins
      • Stimulant 2: medium alone
      • Stimulant 3: beads
      • Stimulant 4: egg white


  • Supernatants from the 48 hour culture were saved in cluster tubes and stored at -80.
    • One sample per stimulant condition:
      • Stimulant 1: caseins
      • Stimulant 2: medium alone
      • Stimulant 3: beads
      • Stimulant 4: egg white


BM059-0 8-5-09 Basophil Activation / 48h Hour Culture / T Reg Studies (Day 0)

BM060-0 8-5-09 Basophil Activation / 48h Hour Culture / T Reg Studies (Day 0)

(Specimens processed with Alyssa Chase)

BM059-0: 2 green tops obtained containing approximately 9mL each for a total volume of 18mL of whole blood. BM060-0: 2 green tops obtained containing approximately 9mL each for a total volume of 18mL of whole blood.

  • Set aside 3 mL of whole blood for Basophil Activation assay.
    • Performed basophil activation as per protocol with the following deviation described by Alyssa for BM059-0: Tube A (RPMI + blood) initially contained staining buffer. To correct, I took all remaining blood and added RPMI to dilute 1:1. The total volume was about 1/2 of that called for in the protocol
    • Stored basophils in 5mL polypropylene tubes at 4C until the following day for flow.


  • Ficoll-separated remaining PBMCs:
    • BM059-0: 3.6 x 10^7 PBMCs (automated counter) --> 36 x 10^6 PBMCs.
    • BM060-0: 3.9 x 10^7 PBMCs (automated counter) --> 39 x 10^6 PBMCs.


  • Set aside 10 x 10^6 PBMCs for 48 hour culture.
    • Did not CFSE-label these cells.
    • Plated 2 x 10^6 CD25+ PBMCs in each of the following four conditions: AIM-V (medium alone, +CD3/CD28 beads, +caseins [alpha, beta, kappa], + egg white).


  • Set aside 10 x 10^6 PBMCs for 7 day culture.
    • CFSE-labeled these cells.
    • Resuspended cells in AIM-V at 4 x 10^6 cells/mL for the 7 day culture.
    • Plated 2 x 10^6 CD25+ PBMCs in each of the following four conditions: AIM-V + IL-2 (medium alone, +CD3/CD28 beads, +caseins [alpha, beta, kappa], + egg white).


  • Both cultures placed in incubator.
    • 48 hour culture will be removed on 8-7-09.
    • 7 day culture will be removed and harvested on 8-12-09.

BM058-0: 2 green tops obtained containing approximately 9mL each for a total volume of 18mL of whole blood.

(Specimen processed with Alyssa Chase)

  • Set aside 3 mL of whole blood for Basophil Activation assay.
    • Basophil activation performed as per protocol, with the following deviation described by Alyssa: Error during preparation of Ab cocktail: 110 uL of Ab alone were initially added to test tubes B-G (rather than Ab:Staining buffer). We then added enough staining buffer to these tubes to maintain the protocol's ratio of Ab:Staining buffer. The normal protocol was followed for tubes I-K.
    • Stored basophils in 5mL polypropylene tubes at 4C until the following day for flow.


  • Ficoll-separated remaining PBMCs:
