Description | Protein tyrosine phosphatase, receptor type C (CD45), also known as PTPRC is a member of the protein tyrosine phosphatase (PTP) family which is known for its function to serve as signaling molecules and to regulate a variety of cellular processes such as cell proliferation, differentiation, mitotic cycle and oncogenic transformation. CD45 is found to be expressed specifically in hemotopietic cells. CD45 consists of an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains. It serves as an essential regulator of T-cell and B-cell antigen receptor signaling through either direct interaction with components of the antigen receptor complexs or by activating various Src family kinases required for the antigen receptor signaling and it also can suppress JAK kinases. |

LWB Cell Preparation | 1. For each patient sample, label three tubes A, B, and C. Also label each tube with the sample identification number. 2. Place 50 µL PBS reagent into Tube A, Mouse IgG2a FITC Control reagent into Tube B, and of the 1ug CD45-FITC reagent into Tube C. 3. For each sample tube, use a fresh micropipettor tip and carefully add 50 µL of human Peripheral blood into the bottom of each of the three labeled tubes. All tubes refill to 100ul. 4. Vortex thoroughly at low speed for 3 seconds and incubate for 15minutes at room temperature (20°C–25°C). Repeat this step again. NOTE Protect samples from direct light during this incubation procedure and exercise care to prevent blood from running down the side of the tube. If whole blood remains on the side of the tube, it will not be stained with the reagent. 5. Add 250uL of room temperature (20°C–25°C) lysing solution to each tube. Immediately vortex thoroughly at low speed for 3 seconds and incubate for 10– 12 minutes at room temperature (20°C–25°C) in the dark. Do not exceed 12 minutes. 6. Immediately after incubation, add 1 mL of PBS with 1% FBS to each tube. Centrifuge tubes at 1500rpm for 5 minutes at room temperature (20°C–25°C). 7. Aspirate the supernatant leaving approximately 50 µL of residual fluid in the tube to avoid disturbing the pellet. 8. Repeat 6,7steps again. 9. Vortex thoroughly at low speed to resuspend the cell pellet in the residual fluid and then add 0.3 mL of PBS to each tube. Vortex thoroughly at low speed for 3 seconds. Make sure the cells are well mixed with the fixing solution. 10. The cells are now ready to be analyzed on the flow cytometer. Cap or cover the prepared tubes and store at 2°C– 8°C in the dark until flow cytometric analysis. NOTE Analyze the fixed cells within 2 hours after staining.Over 2 hours add 0.3 mLof PBS with 1% paraformaldehyde to each tube. |
