Application Details

Application Notes: It is recommended for use in flow cytometry. This reagent is effective for direct immunofluorescence staining of human tissue for flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is less or equal to 1.0 µgper million cells in 100 µL volume.

Comment:

Allophycocyanin (APC), Abs/Em: 651/662 nm.

Reagent Preparation:

1. Transfer the sample of blood to a 12 x 75 mm polystyrene test tube (10^6 cells). 2. Add CD25 APC and mix gently with a vortex mixer. The optimal volume should be determined by the individual laboratory. 3. The recommended negative control is a non-reactive APC-conjugated antibody of the same isotype. 4. Incubate in the dark at room temperature at 4°C for 30 minutes or at room temperature (20-25 °C) for 15 minutes. 5. Add 1,5 mL of Lysing Solution to each sample and mix gently with a vortex mixer. Incubate for 10 minutes at room temperature in the dark. 6. Centrifuge at 1000 x g for 5 minutes. Gently aspirate the supernatant and discard it leaving approximately 50 µl of fluid. 7. Add 2 mL 0.01 mol/L PBS (It betters that it containing 2% bovine serum albumin) and resuspend the cells by using a vortex mixer. 8. Centrifuge at 1000 x g for 5 minutes. Gently aspirate the supernatant and discard it leaving approximately 50 µl of fluid. 9. Resuspend pellet in an appropriate fluid for flow cytometry, e.g. 0.3 mL PBS. The PBS should contain 1% paraformaldehyde (fixative) if samples are not analysed the same day. 10. Analyse on a flow cytometer or store at 2-8 °C in the dark until analysis. Samples can be run up to 24 hours after lysis.

Restrictions: For Research Use only

Handling

Format: Liquid

Buffer: The conjugate is provided in liquid form in buffer containing PBS, 1% BSA and 0.09 % Sodium azide, pH 7,4.

Preservative: Sodium azide

Precaution of Use: 1. The device is not intended for clinical use including diagnosis, prognosis, and monitoring of a disease state, and it must not be used in conjunction with patient records or treatment. 2. This product contains Sodium azide (NaN3), a chemical highly toxic in pure form. At product concentrations, though not classified as hazardous, Sodium azide may react with lead and copper plumbing to form highly explosive build-ups of metal azides. Upon disposal, flush with large volumes of water to prevent metal azide build-up in plumbing. 3. As with any product derived from biological sources, proper handling procedures should be used.

Storage: 4 °C

Background: CD25 is a 55 kDa glycoprotein, also known as the low affinity IL-2Ralpha, Ly-43, p55, or Tac. It is expressed on activated T and B cells, thymocyte subset, pre-B cells, and T regulatory cells. association with CD122 (IL-2Rbeta) and CD132 (common gamma chain), CD25 forms the high affinity signaling IL-2 receptor. The PC61 antibody is able to block IL-12 binding to its receptor and inhibit IL-2 stimulated cell growth.

Pathways: JAK-STAT Signaling, Growth Factor Binding, Activated T Cell Proliferation
