Catalog No. ABIN2144249

Product Details anti-CD3 Antibody (Biotin)

Target: CD3

Reactivity: Human

Host: Mouse

Conjugate: This CD3 antibody is conjugated to Biotin

Application: Flow Cytometry (FACS), Immunohistochemistry (IHC), Functional Studies (Func), Immunofluorescence (IF), Western Blotting (WB), Immunocytochemistry (ICC)

Characteristics: 4AOKT3 reacts with CD3, a 20-26 kDa molecule, which is expressed on all mature T lymphocytes (approximately 60-80 % of normal human peripheral blood lymphocytes), NK-T cells and some thymocytes.

Clone: 4AOKT3

Isotype: IgG2a

Application Details

Application Notes: Optimal working dilution should be determined by the investigator.

Assay Procedure:

• Take 100 μL peripheral blood anticoagulated by EDTA and add to the bottom of 5 mLtube,
• Add appropriate amount of antibody to the bottom of flow tube mixing with the whole blood, incubate for 30 minutes at room temperature,
• Add 2 ml1×RBC lysis buffer, incubate for 10 minutes after mixing, dissolve red blood cells (recommended: RBC lysing Solution 10×,Cat.: FXP001),
• Sample tube is set to 1000 rpm centrifugation for 5 minutes, discard the supernatant,
• Add 2 mLPBS wash buffer to resuspend the cells, then 1000 rpm centrifugation for 5 minutes, discard the supernatant,
• Add appropriate amount of fluorescent-labeled Streptavidin and incubate for 20 minutes away from light at room temperature.
• Repeat step 5.
• Add 0.5 mLPBS wash buffer to resuspend the cells and detect by flow cytometry (sample should be determined on the day on the machine and can also be added fixation overnight at 4 °C then measured).
• [PBS wash buffer: PBS +1 % FBS +0.1 % NaN3, Cat.: FXP005]
• [Cell fixation: 2 % formaldehyde solution]

Target Details for CD3

Target: CD3

Alternative Name: CD3 (CD3 Products)

Background: CD3 associated with the T-cell receptor a/b or g/d dimer also plays a role in T-cell activation and signal transduction during antigen recognition.* CD3 mAb is used to count mature T cells in blood.

Pathways: TCR Signaling, Ubiquitin Proteasome Pathway
