Apply Adhesive Plate Sealer

To maximize the use of plates, an adhesive plate-sealing sheet is including in each kit. Using fingers and thumb, adhere firmly to plate. Use a razor to cut sheet and expose wells to be used in assay.

Balance & Spin Vials for PBMC Isolation

Carefully balance the weight of the tubes in centrifuge buckets and spin at 800g for 30 minutes.

Collect Mononuclear Cells

Collect mononuclear cells after density gradient centrifugation.

Create Humidified Chamber

After coating the plate with Capture Solution, incubate plate at 4°C overnight in humidified chamber.

Streamline research with our extensive library of cryopreserved PBMC with >90% post-thaw viability and functionality comparable to fresh. Available either uncharacterized, characterized, HLA-typed, immunotyped, genotyped, and NK reactivity.

Plating Cells & Tapping the Plate

Plate PBMC 100ɥl/well using large orifice tips. After adding cells & antigens, cover plate & gently tap each side.

Prewetting the Plate: ImmunoSpot Assay

Prewetting a 96-well plate for an ImmunoSpot® Enzymatic or FluoroSpot ELISPOT Assay, plus how to fix your plate if it's leaking. Make sure all solutions are freshly-prepared.

Rinse Plate & Remove Underdrain

Stop reaction by rinsing plate under tap water and decanting 3 times;remove protective underdrain and rinse again. Place face down in running hood for 2 hours or on paper towels for 24 hours on bench top.

Storing Medium

Store prepared Anti-aggregate Wash Medium in a 37°C CO2 incubator with cap loosened for 20 minutes. This help reset the pH and temperature.

Storing the Cells

After PBMC isolation, cells can be stored for 24 hours in a 37°C incubator with the cap loosened.

Thawing Cryopreserved PBMC
