Description :CD3, also known as T3, is a member of the Ig superfamily and primarily expressed on T cells,NK-T cells, and at different levels on thymocytes during T cell differentiation. CD3 is composedof CD3ε, δ, γ and ζ chains. It forms a TCR complex by associating with TCR α/β or γ/δ chains.CD3 plays a critical role in TCR signal transduction, T cell activation, and antigen recognitionby binding the peptide/MHC antigen complex
Verified Reactivity :Mouse
Antibody Type :Monoclonal
Host Species :Rat
Immunogen :γδTCR-positive T-T hybridoma D1
Formulation :Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide
Preparation :The antibody was purified by affinity chromatography and conjugated with PE/Fire™ 640 underoptimal conditions.
Concentration :0.2 mg/mL
Storage & Handling :The antibody solution should be stored undiluted between 2°C and 8°C, and protected fromprolonged exposure to light. Do not freeze.
Recommended Usage :Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometricanalysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per million cellsin 100 µL volume.

抗体二抗上连接有荧光染料。直接标记染色背景低,实验程序少尽量减少实验工序和过程,以保证实验的真实和准确性。因此在条件允许的范围内,建议尽量用直接标记的抗体进行实验。 3、流式抗体荧光标记的选择: 如果实验中检测单一指标:不同荧光标记在不同的仪器上强度不同。以某仪器为例:PE >APC >PE-Cy5 >PerCP >FITC >PerCP-Cy5.5,通常来说,PE最强,适用于弱表达抗原。FITC强度较弱,适用于强表达抗原,使用范围比较广。用户需根据检测的目标蛋白进行具体选择。 如果同时检测多个
