Biolegend, 115547, Purified anti-mouse CD19 (Maxpar® Ready) Antibody, 100μg

CD19 is a 95 kD glycoprotein also known as B4. It is a member of the Ig superfamily, expressed on all pro-B to mature B cells (during development) and follicular dendritic cells. Plasma cells do not express CD19. CD19, in association with CD21 and CD81, forms a molecular complex integral to B cell activation.

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.
