    C57BL/6 mouse frozen spleen section was fixed with 4% paraformaldehyde (PFA) for 10 minutes at room temperature and blocked with 5% FBS for 30 minutes at room temperature. Then the section was stained with 10 µg/ml of anti-mouse CD34 (clone MEC14.7) Biotin, anti-mouse CD3 (clone 17A2) Alexa Fluor® 647 (green) and anti-mouse B220 (clone RA3-6B2) Alexa Fluor® 488 (blue) overnight at 4°C, followed by 2.5 µg/mL of Alexa Fluor® 594 Streptavidin (red) for two hours at room temperature. The image was captured by 10X objective.

Description

CD34 is a highly glycosylated hematopoietic progenitor antigen. Two isoforms of CD34 have been reported to be generated by alternative splicing. This antigen is expressed on hematopoietic progenitors as well as on endothelial cells, brain, and testis. CD34 is thought to function as an adhesion molecule for early hematopoietic progenitors mediating the attachment of stem cells to extracellular matrix or stromal cells. CD34 is phosphorylated on serine residues by PKC.

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤1.0 µg per million cells in 100 µl volume. For immunohistochemistry, a concentration range of 5.0 - 10 µg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

The MEC14.7 antibody does not stain bone marrow cells like some other mouse CD34 antibodies, probably because the antibody recognizes a different epitope from other mAbs. Additional reported applications (for the relevant formats) include: immunoprecipitation, Western blotting6, and immunohistochemistry of acetone-fixed frozen sections and paraffin-embedded sections2,4,5,6.
