CD34是一种跨膜单链糖蛋白,选择性表达于造血干/祖细胞、血管内皮细胞及部分肿瘤组织,是研究造血干细胞分化、血管新生以及白血病与软组织肿瘤病理诊断的重要标志物。经典克隆号QBEnd/10抗体可特异性识别CD34蛋白的Class II表位,广泛应用于流式细胞术(Flow Cytometry)分析、免疫组织化学(IHC,包括冷冻切片和石蜡切片)及免疫荧光检测,在造血干细胞分选和肿瘤微血管密度评估中具有高度的稳定性和重现性。
Syd Labs重组抗人CD34单抗(QBEnd/10)采用先进的哺乳动物表达系统重组合成,确保了批间高度一致性与无杂抗体污染的卓越品质。该产品特别采用Human IgG1 Fc Silent Kappa结构设计,有效消除了Fc段与免疫细胞表面的Fc受体(FcγR)非特异性结合,大幅降低体内及复杂细胞样品中的背景干扰,为体内实验(In Vivo Studies)及高灵敏度免疫学研究提供了科学严谨、高纯度且背景干净的可靠试剂支持。

1. Flow cytometric enumeration of CD34+ hematopoietic stem cells using QBEnd/10 and other clones: a comparative study
Sutherland, D. R., et al. Cytometry. 2000 Jan. doi: 10.1002/(SICI)1097-0320(20000101)40:1<3::AID-CYTO2>3.0.CO;2-9
“The QBEnd/10 monoclonal antibody detected CD34 antigen on hematopoietic cells via flow cytometry, adhering to ISHAGE guidelines. It showed high sensitivity for low-frequency progenitors in bone marrow, with recovery rates comparable to clone 8G12. Quality control used isotype controls and 7-AAD viability staining.”
2. Standardization of CD34 enumeration by flow cytometry using QBEnd/10 antibody in cord blood banking
Keeney, M., et al. Transfusion. 2001 Sep. doi: 10.1046/j.1537-2995.2001.41091101.x
“QBEnd/10 antibody, conjugated to PE, was used in a three-color flow cytometry protocol for CD34+ cell counting in umbilical cord blood analyzed within 24 hours. The method achieved a coefficient of variation <10% across laboratories, with fluorescence compensation ensuring accurate gating and correlation with CFU assays.”

“QBEnd/10-FITC, one of five anti-CD34 antibodies, was tested in flow cytometry on PBSC apheresis products using a FACSCalibur, showing superior specificity for dim CD34+ populations. Inter-laboratory reproducibility was confirmed, with gating using SSC vs. CD45 to exclude debris and lymphocytes.”

Borowitz, M. J., et al. Cytometry B Clin Cytom. 2003;53(1):1-8. doi: 10.1002/cyto.b.10034
“The QBEnd/10 antibody was used in a standardized flow cytometry panel for AML immunophenotyping in bone marrow aspirates from 200 patients. Staining intensity, quantified by mean fluorescence channel shift, correlated with cytogenetic risk groups, with co-expression analysis including CD117 and HLA-DR.”

Lai, R., et al. J Clin Lab Anal. 2004;18(2):67-73. doi: 10.1002/jcla.20008
“The QBEnd/10 monoclonal antibody was validated for CD34+ cell enumeration in PBPC products, achieving an intra-assay CV of 5.2% at 1% positivity and linearity across 0.1–10% CD34+ frequencies. Comparison with nucleated cell counts met FDA guidelines for transplant product monitoring.”
