Biolegend, 123143, Purified anti-mouse F4/80 (Maxpar® Ready) Antibody, 100μg

F4/80, also known as EMR1 or Ly71, is a 160 kD glycoprotein of the epidermal growth factor (EGF)-transmembrane 7 (TM7) family. F4/80 has been widely used as a murine macrophage marker. It is expressed on a majority of tissue macrophages, including macrophages in the lung, gut, peritoneal cavity, thymus, and red pulp of the spleen, Kupffer cells, Langerhans cells, microglia, and certain dendritic cells. It is not expressed on macrophages located in the T cell areas of the spleen, lymph node, or Peyer's patch. The biological ligand of F4/80 has not been identified, but it has been reported that F4/80 is required for the induction of CD8 + T cells-mediated peripheral tolerance.

Q: Can I obtain CyTOF data related to your Maxpar® Ready antibody clones?
A: We do not test our antibodies by mass cytometry or on a CyTOF machine in-house. The data displayed on our website is provided by Fluidigm®. Please contact Fluidigm® directly for additional data and further details.

Q: Can I use Maxpar® Ready format clones for flow cytometry staining?
A: We have not tested the Maxpar® Ready antibodies formulated in solution containing EDTA for flow cytometry staining. While it is likely that this will work in majority of the situations, it is best to use the non-EDTA formulated version of the same clone for flow cytometry testing. The presence of EDTA in some situations might negatively affect staining.
Q: I am having difficulty observing a signal after conjugating a metal tag to your Maxpar® antibody. Please help troubleshoot.
A: We only supply the antibody and not test that in house. Please contact Fluidigm® directly for troubleshooting advice: http://techsupport.fluidigm.com/
Q: Is there a difference between buffer formulations related to Maxpar® Ready and purified format antibodies?
A: The Maxpar® Ready format antibody clones are formulated in Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and EDTA. The regular purified format clones are formulated in solution that does not contain any EDTA. Both formulations are however without any extra carrier proteins.
