CD34, also known as gp105-120, is a type I monomeric sialomucin-like glycophosphoprotein with an approximate molecular weight of 105-120 kD. Selectively expressed on the majority of hematopoietic stem/progenitor cells, bone marrow stromal cells, capillary endothelial cells, embryonic fibroblasts, and some nervous tissue, CD34 is a commonly used marker to identify human hematopoietic stem/progenitor cells. According to the differential sensitivity to enzymatic cleavage, four groups of epitopes of CD34 have been described. CD34 mediates cell adhesion and lymphocytes homing through binding to L-selectin and E-selectin ligands.

- Recommended Usage
-
Each lot of this antibody is quality control tested by immunofluorescent staining in formalin-fixed, paraffin-embedded (FFPE) lymphoid tissue, and the oligomer sequence is confirmed by sequencing. TotalSeq™-Bn antibodies are compatible with the 10x Visium CytAssist Gene and Protein Expression Assay.
To maximize performance, it is strongly recommended that the reagent be titrated for each application, and that you centrifuge the antibody dilution at 14,000xg at 2 − 8°C for 10 minutes before use. Carefully pipette out the liquid avoiding the bottom of the tube when handling. To determine and optimize dilutions for the addition of Totalseq™-Bn antibodies into pre-designed antibody panels, refer to 10X Genomics Custom Add-on Antibody Optimization guide.

-
This antibody is effective in immunohistochemistry (IHC).
The BioLegend QBEnd/10 monoclonal antibody detects the CD34 antigen. It stains the cytoplasm of endothelial cells of vascular tissue with some cross reactivity to basement membrane collagen. In tumors this monoclonal antibody is valuable in labelling the vascular endothelium of Kaposi's sarcoma, tumors involving the liver, spindle shaped tumors and any other highly vascular neoplastic or normal tissue.
**We recommend a quick spin prior to opening the vial.
Positive tissue (human): Skin, tonsil or other highly vascular tissue. - Additional Product Notes
-
TotalSeq™-Bn reagents are designed to profile protein levels following an optimized protocol in spatial transcriptomics. Compatible spatial biology devices (e.g. Imaging System, 10x Genomics Visium Spatial CytAssist Gene and Protein Expression instruments and reagents) and sequencer (e.g. Illumina analyzers) are required. TotalSeq™-B reagents are not compatible with the 10x Genomics Visium system. The complete barcode sequence may be provided upon request. Please contact technical support for more information, or visit TotalSeq™-Bn Reagents for 10x Genomics Visium CytAssist Gene and Protein Assay.
