Cd34 pe ram34

Manufactured by BD

CD34 PE (RAM34) is a laboratory reagent used for the detection and identification of CD34-positive cells in biological samples. It contains a phycoerythrin (PE)-conjugated monoclonal antibody that specifically binds to the CD34 antigen expressed on the surface of certain cell types, such as hematopoietic stem and progenitor cells. This reagent can be used in flow cytometry applications to enumerate and characterize CD34-positive cells within a sample.

For analysis of AGM-HSC populations, cells were stained with either (i) cKit APC (2B8, DB Pharmingen) and CD34-PE (RAM34, BD Pharmingen), (ii) VE-Cadherin (clone 11D4.1, BD Pharmingen) followed by anti-rat Tricolour (PeCy5) antibody and CD45-PE (30-F11, eBioscience) (Invitrogen) or (iii) CD45-PE, VE-Cad:PeCy5, cKit-APC, CD34 staining the rat antimouse CD34 biotin (BD Pharmingen) followed by incubation with the secondary antibody anti-streptavidin PeCy7 (BD Pharmingen). Fetal liver cells were stained for lineage markers using purified rat antimouse antibodies the Lin-(Ter119, Gr1, CD4, CD8, B220) followed by anti-rat Tricolour (Pe-Cy5) secondary antibody. For cKit and Sca-1 staining, cKit-APC and anti-Sca-1-PE were used. . Lastly CD34 biotinylated antibody (BD Pharmingen) combined with the streptavidin PeCy7 was used for CD34 staining. For immunophenotyping of bone marrow, cells were stained for lineage analysis with purified anti mouse Ter119 (erythroid), Gr1 and Mac-1 (granulo-monocytic), B220 (B cells), CD3, CD8 and CD4 (T cell) followed by anti-rat Tricolour (PeCy5) antibody and ckit APC, Sca-1 PE and CD34 FITC. + Kit + Sca. For LT/ST HSC compartment analysis, cells were stained as before for KLS, and CD34. Cells were analysed for HSC and progenitor compartments by flow cytometry using the Cyan ADP flow cytometry platform (Beckman Coulter, High Wycombe, UK).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
