BD Pharmingen- Purified NA-LE Mouse Anti-Human CD3_BD Pharmingen
产品信息
抗原名称
CD3
宿主
Mouse BALB/c IgG1, κ
免疫原
Human infant thymocytes and peripheral blood lymphocytes from a Sézary Syndrome donor
简单描述
The UCHT1 monoclonal antibody specifically binds to the human CD3ε-chain, a 20-kDa subunit of the CD3/T cell antigen receptor complex. CD3ε is expressed on 70-80% of normal human peripheral blood lymphocytes and 60-85% of thymocytes. Studies from the HLDA Workshop show that this antibody is mitogenic for CD3ε-positive cells when used in conjunction with costimulatory agents such as pokeweed mitogen or anti-CD28 antibody. CD3 plays a central role in signal transduction during antigen recognition. The UCHT1 antibody stains both surface and intracellular CD3ε unlike the other CD3 clone, HIT3a, that stains only extracellular CD3ε.

产品详情
NA/LE
NA/LE refers to the culture and purification methods and buffer used to produce purified antibodies with no azide and low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.NA/LE are perfectly suited to be used in culture or in vivo (for nonhuman studies) for functional assays — blocking, neutralizing, activation or depletion — where the presence of azide may damage cells or exogenous endotoxin may signal or activate cells.

Flow cytometric analysis of CD3 expression on human peripheral blood lymphocytes. Human whole blood was stained with either Purified NA/LE Mouse IgG1 κ Isotype Control (Cat. No. 554721; dashed line histogram) or Purified NA/LE Mouse Anti-Human CD3 antibody (Cat. No. 555329/562280/562310; solid line histogram). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). The cells were washed and then stained with FITC Goat Anti-Mouse IgG/IgM (Cat. No. 562292; dashed line histogram). The erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). The fluorescence histograms were derived from events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometry was performed using a BD™ LSR II Flow Cytometer System.
